Thanks a lot. UFEI and boot failures are just scary especially when you don't have absolutely everything backed up. You're such a great resource and your explanations are so good and straightforward. I just got a new 7945HX laptop and I've heard that you should not update the BIOS when asked; so I need to sort that but just love this processor (CB=34800!). Thanks for all you do! It is nice to have someone that has your back when you are in PC-Hell...
in my experience all windows systems are faulty and conflicts in software and problems with registry (by too much install deleting and then installing again the same software). theres always some f... issue and the fastest solution is re-installing Windows instead of searching for a needle in a haystack. I loose more time trying to find a solution unless the solution is obvious! so many hours wasted no thanks new install keep the old files no need to back up because theyr always on an another partition. 😊
@@jDurMC Windows 10 installation media has an option to reinstall Windows without losing your files or settings, but I honestly don't trust it to actually work as advertised. Once I have a full backup of the drive I almost lost which brought me to this video I might screw around and see if I do genuinely keep all my work programs, games, and personal files, but not until I have that backup.
So I definately was in a state where I could not boot into windows and man am I thankful for you taking one for the team and making this tutorial. You both taught me something new and walked me through a process I thought I was gonna be stuck in forever. I am am seriously so thankful. Will be watching more videos to see what else I can learn since I have a new PC I plan to build this year.
SO GLAD that I've found this video instead of those crappy tutorials on google that just are adverts for shady boot programs for USB drives. It actually helped me and let me understand what was the problem in the first place. Giga props
I’ve been building and working on windows pc’s for years! I cannot tell you how many times I’ve had to fix peoples systems who have ruined their boot files. Every time I painfully followed a tutorial, hoping it would be the last time I’ll tell you this after watching this I got it down pat and I’ve even tested it!!!Thank you so much.!
Outstanding content and delivery. As an old DJ, I want to compliment you on your voice, tone and delivery. I really enjoyed the video and would enjoy one on MBR restore as well. Thanks
The reason LIST VOL showed the USB drive is because VOL is independant from the selected disk, and shows all volumes on the system. You did not do it wrong, however it was not necessary to select the disk when you are using the volumes as a reference. If you do select the disk, LIST PART is more accurate as it will show the partitions on the selected disk. Both will give you the same results, but just wanted to let you know that you do not need to select the disk if you are going to select the volume rather than the partition.
@@CyberCPU Just got the repair loop issue, when in advanced options on each the options it asks for password but does not recognise it, is there so many try`s limit on it ? and is there a workaround ? ... really stuck as it`s my main use laptop....
@CyberCPU sent email to you. Please please reply can't help you if you can't. At least I will know you actually seen the email. thx so much...email is from rkral
THANK YOU THANK YOU THANK YOU for making this video!!!!!! WE fixed the bootloader after my 10 year old Daughter corrupt it by accident. I was a little bit upset at first, however I told her we are going to fix it together. After looking around on youtube, I came accross your video showing how to fix the bootloader UEFI Partition. After watching the video together many many times we started the process of executing the dos commands. Once all of the commands where done setup by step and the computer was turned off. I let my Daughter have the honnor of pressing the poweron button on the computer as we held our breath, windows booted up :) thanks again for making your videos for all of us to learn and enjoy them :)
With a few slight modifications to what you did because my situation was a little different I was able to get Windows back up and running, I really appreciate this video!
Man! i was stuck for eight hours trying to fix this. The ONLY thing you missed was you has to also map your windows partition drive letter and use it in the line to recreate the UFI.... You are a Genius!!!!
Dude YATB!!!! You are incredible, my desktop would not boot up from my m.2 drive. I thought I was toast, but thanks to your video I am now back in business. This will sound made up, but I literally spent 2 days and countless hours trying to clone my M.2 drive to an SSD because I did not think my motherboard supported an m.2 boot. I am embarrassed to say I went out and bought a new motherboard, new memory, new cooler, etc. and rebuilt my PC, still did not work. I worked on this since 2am and could not get it to work, went to bed and woke up and started another Clone software. it was running from the am until 7:30 pm with 23% complete before I found your video. Thank you, thank you, thank you!
I'm pretty much exactly where you were! so many new parts, so much time, so sad and frustrating! Had micro-center build a $3,600 computer for my son. For 3 months it worked well, for the last 3 months it's consumed more time and another $650-$700. If this doesn't fix it my head will explode. . . 🤞
Thank you so much for this video. I stupidly deleted the bootloader using the AOMEI partition tool without understanding. After restart saw a black screen with "reboot and select proper boot device or insert boot media in selected boot device and press a key issue". Frantically was looking for an online solution (which also included clean installed that failed) for hours and came across your video. Just with faith, tried your guide and it fixed the corrupted boot. Didn't lose any personal data as it was a new machine I was tinker.
I would have been completely lost without your video! Thank you so much for this. I appreciate you explaining the steps instead of just moving through them. I work with subject matter experts every day and you're a really great educator on top of knowing your stuff. Those two things don't often go hand in hand. kudos
What was the problem you were facing Was it that when you choose a boot device it brings you back to the UEFI menu ? I'm facing this problem and I want to be sure before trying
An interesting thing to know is that you can create a virtual drive (VHD) and boot from this in the bcdboot database. This is a great way to 'dual boot' if you want two copies of Windows (one being a sandbox) or to tinker on a system without affecting the main system.
you seem like you know what your doing so i would like to ask for your help in the middle of the video when i did V: /fs:fat32 it started installing something thats not what happend to the guy who made the video however do you know how to help me in that case?
A month ago after a Windows update on my Dell XPS, the computer went into a constant cycle of restarting once the Dell logo appeared. I researched the issue, tried different solutions offered on forums to include repairing and resetting the computer, and nothing worked. The other day I spent an hour on the phone with Dell support in India who I could barely understand, and none of their solutions worked. They sent an email suggesting to reset the PC, which I'd already tried and which failed due to problems with boot files, and that didn't work. Although they said to reply with any issues and they said they were there to help, they ignored me after I responded. Frustrated, I watched your 20 minute video and voila, my PC works again - and it works without me having lost any of my data! Thanks a lot!
You are genuinely a life saver. I had to take a few extra steps because my boot drive wasn’t appearing on diskpart, so if anyone is also having that problem: 1) Download some Intel RST drivers and load them onto that USB drive 2) Instead of selecting repair, select install windows to go to the drive selection screen (won’t actually be reinstalling it) 3) Load the drivers. The boot drive should now show up both in the drive selection screen and on diskpart. 4) hit shift + f10 to bring up the cmd prompt and go from there
Congratulations for this vídeo! I had tried several others ways to fix the "Windows dont boot after SSD upgrade" issue and it was the only one that solved it!
Thanks a lot! Para la gente que hable en español: Este es el mejor tutorial que he encontrado, funciona correctamente, lo pueden seguir casi al pie de la letra sin entender inglés, salvo en la parte en la que tienen que elegir la partición de UEFI, pero ahí lo único que deben tener en cuenta es que es la participación de 100 megas
Lifesaver! I was meshing around with another Windows installation and suddenly my main bootloader was screwed. This video helped a lot to get it back. Thanks man!
LIFESAVER!!! Mission critical system, with failure after a SSD drive upgrade via clone. Would not boot afterwards, was about to panic until I found your video. I followed your instructions, which did EXACTLY what you said it would, thus saving time and money, avoided downtime, and probably saved my job!
I needed this video so much bro!! My other laptop is just resting on my bed for more than a month... I agree i was lazy to fix it but you just made the video on the exact same problem im facing. Love your content keep it up
Besides the benefit of hands on learning and a working windows 11 system, I walked away wanting more. I'm going to use your videos as a classroom. You really know how to teach a class. The info is clear, concise, logical and presentation simple and to the point. The video is very interesting. Thanks.
THANK YOU!!! This was an absolute life saver. After 10+ hours of googleing and attempting other fixes on youtube, this FINALLY did the trick. I had my reservations as i was unable to back my machine up. I was able to manually back up my user files using cmd, but that was about as "backed up" as i could get, so had no choice but to take the risk in the formatting. I had few slight differences, but for the most part, everything worked the same. Only thing i couldnt then work out was at the very end when you mentioned using the USB stick again and upgrading the pc. Thank you again, cant express my gratitude enough.
Great video. I actually tried a few years ago to fix a system under w7 that had a corrupted boot/os and was never able to. The problem there was that when windows was updating or fixing an issue there was a power failure just during the boot screen, and it messed everything; it only loaded an error screen and not even boot options. Can't remember if it had a MBR or what, but I am glad to know that there are easyier methods to fix this for w10 or w11.
Hello my friend, can you please help me? My laptop just died during startup because it had very low battery. Now it keeps going to bios screen and Windows doesn't load. Would this video help me?
Hey I have the same issue but it's windows 10, whenever I want to open anything like reset or startup fix it crashes with error session 1 initialization failed, how did you fix it? Should I do the video? Don't wanna mess it up even more.
Your a straight savage for that one man. Been following several other videos trying to fix the damn loop "windows cannot repair automatically" and none of these guys made it so simple as to just rebuild the whole boot partition manually... derrrrr. You are the man. Wish I found your video first. Would have saved me half a days wasted time. Thanks again. "Someone get the man a beer!" Wooohooooo! Life saver...
Replaced my older ssd with a m.2 nvme ssd went through all the dir of my c drive really couldnt find users and windows install. so I did a fresh install just disconnected my other drives so i dont wipe em. Now im trying to figure out how i can get the data from my old ssd like apps, photos, and important files
Very much appreciate this content. I was just about to give up and abandon the data on my unbootable drive. Your walk-through was the right amount of simple, patient, and thorough. And I especially like it because it worked. 😂
fantastic! I had both bitlock on and windows could not figure out how to fix it. But removing the Bitlocker in the CMD and then deleting the UEFI bootloader and setting it up again as you did was perfect 🙌🙌
I am going to try this on my laptop. I am so grateful for videos like yours that helps us who can't afford to pay someone to fix it for us. I love learning new things. Thank you so much for sharing your video.
This video is just about how to fix a non booting BCD. However it does not show how to restore or recreate the recovery console (installed in its own partition, usually at end of disk just after the normal windows partition). In some cases Windows image updates will not run if: - (1) the ESP/EFI partition is full, i.e. too small to fit the bootloader, the "BCD" file, and various admin tools that have been placed there, or alternate bootloaders if you have installed "dualboot" for loading a Linux, which installs its own EFI tools there (like a Linux "Grub" boot loader), or other tools (like some offline backup system solutions, or offline antivirus, or offline defragmenters, or offlien hardware diagnostic tools specific to your machine). - (2) the updated recovery console cannot fit in the existing recovery partition: Windows will then try reducing the Windwos partition at end, to make space for a newer version, but will leave the existing windows recovery partition there (the Windows recovery console partition is a standard NTFS partition, it is just formatted with a flag that "hides" it during normal boot, and avoids mounting it with a drive letter, but you can perfectly mount it using diskpart and see its content: it may be corrupted in which case the recovery console will crash or will not load) Recreating the recovery partition is still possible; and you can also delete it using "diskpart" and delete superflous old recovery partitions that sometimes cumulate uselessly on disk. But it requires having a copy of it: you have to know how to manage partitions and recreate it with a sufficient size (usually about 655MB, its actual sizes changes a bit when it is updated when installing or updating windows, so in doubt you can give it a little more space such as 700MB). Just make sure you place this recovery partition immediately after the windows partition (which can be reduced using "diskpart" to leave a sufficient free space after it, just before creating a NTFS partition of 700MB, then assigning it the type GUID "de94bba4-06d1-4d40-a16a-bfd50179d6ac", and the GPT attributes "0X8000000000000001" But creatign that partition is not enough, you need tor restore its content, and for that you must first mount it and assign a temporary driver letter for it (e.g. you can use diskpart, select the 650MB..700MB NTFS volume you created for it, and then "ASSIGN LETTER=R" before exiting diskparty Then you need a directory named "\Recovery"; if the "R:" is the drive letter you chose to mount, the normal file attributes for the Recovery partition is "ATTRIB /D R:\Recovery +s +h +i",you can see its effective attributes with "R:" to select the drive, CD "\" to go the root folder, then "ATTRIB /D" to list all files and directories in that root folder, you should see this line SH I R:\Recovery in addition to another line for the hidden "System Volume Information" directory, whose content does not matter, but that Windows creates to store some diagnostic logs (e.g for CHKDSK) or some additional copies of critical data (e.g. Bitlocker account access tokens and signatures, Azure account keys, encryption keys...) The content needed of this Recovery folder is just another hidden directory named "WindowsRE", which has the same "+S +H +I" file attributes. Inside it there are just 3 files: "boot.sdi", "ReAgent.xml" and "winre.wim" (they also have the same "+S +H +I" file attributes, to hide by default in Windows Explorer), with sizes about 3MB and 555MB respectively. The "ReAgent.xml" file is very small, but cannot be copied from one PC to another, as it is specific to the partition layout on our disk: it is created using a command line tool name "Reagentc", which checks its validity with the BCD entries that you can control it and the EFI BIOS will use to boot in that recovery console, after checking that it is not corrupted and matches the digital signatures stored in the BCD for the "boot.sdi" file, which then load the "reagent.xml" to check it, and locate the "winre.wim" and check also its security signature: "winre.wim" contains a windows image with the signed Windows PE kernel, a few signed critical drivers, the recovery environment with some .EXE, .DLL for a few command tools you can use in the console and the default Wnidwos diagnostic tools and restore tools). So you need a safe copy of "boot.sdi" and "winre.wim" (they are unfortunately not visible in the Windows ISO image: either you can use a copy from another Windows 10 or Windows 11 installation with the same x86, AMD64 or ARM64 architecture;, or you need to extract them from the windows image in the mounted ISO, by using DISM tool to mount the windows image in a temporary folder; there are some tools that allow to inspect what is in .wim or .esd windows images that are found in Windows ISO files). Once you have restore the 2 files in "R:Recovery\WindowsRE", you must use BCDEDIT to cleanup old nonworking BCD entries, and REAGENTC to restore the BCD entry allowing to boot the WinRE console. Note that when booting from a bootable Windows setup DVD or flash drive, there's no tools proposed to do all this easily: the setup program just proposes you to reinstall windows, there's still no option to just reinstall the recovery partition and restore its working entry in the BCD; the only tool proposed does not even help restoring a working BCD if windows is not booting; that is stupid from Microsoft! But some non-Microsoft emergency disks exist that can do that for you (including from various antivitus/antirootkit third party solutions, or from third backup tools) without having to understand the tricky commands to correctly create and identify partitions in "DISKPART", "BCDEDIT" and "REAGENTC", plus other security attributes you need to check and make all this in the correct order... If all is done correctly, there's a final step to check that the recovery console is now correctly setup: "REAGENTC /INFO" will show if is correctly installed and enabled. As long as this command does not show enabled, there's a problem: there are missing or incorrect files in the recovery console setup, or incorrect data in the BCD entry shown with "BCDEDIT /enum all", where you need to look at an entry with a long GUID matching what REAGENTC shows (but not the REAGENTC shows the GUID without surrounding them in "{braces}", whereas BCDEDIT needs this braces! How Microsoft can be so incoherent in the syntax of its command line tools!)
Note however that even if you don't have a reconvert partition, nothing forbids you from using an external recovery, such as a bootable windows installer on a flash USB drive, which includes the recovery tool.
This actually helps a bunch. Thank you! It was a great learning experience to follow what you did here! Actually got my PC back and running but did end up losing game files but there is more to just gaming in life so it's fine 👍
I had a dual boot setup with Linux on one disk and Windows on another. I cloned my windows drive to a larger drive, but it turned out my UEFI bootloader was on the linux disk. I just couldn't boot into Windows with the larger drive plugged in. I cloned the EFI partition from the linux drive onto the larger drive, then cloned the Windows partition onto the remaining space. Your video provided just what I needed to rebuild the bootloader so I could boot into Windows again. Thanks a million.
Thx for this video that I followed carefuly after a bad W10 update. Unfortunately I've got a new blue screen claiming : "Your PC device needs to be repaired. The boot configuration data file doesn't contain valid information for an operating system. File \BCD Error code 0xc0000098 You'll need to use recovery tool ...etc." After a new PC start up I've got another blue screen claiming this time ;* "The operating system couldn't be loaded because the system registry file is missing or contains errors File \windows\system32\config\system Error code: 0xc000014c" Anyway I learned a bit more on Windows, and continue investigating...Thx again ! Cheers
Rich, this tutorial has literally saved my ass TWICE now on two different systems! So glad I bookmarked it a couple of months back so I could go through it again today. This thing with the Windows bootloader getting messed up/corrupted is getting pretty tiresome. Maybe it's just time I bought a Mac!
@@CyberCPUwell my life sucks lol I did everything did not boot just has that blue screen an now the V: drive can't be found fuk🎉 I did not even have that specific blue screen till I tried this method
@@CyberCPUmy drives are all good and health on all scans. I tried using the same format partition the fat32 efi partition and created the boot files just like you showed. Now when my computer rebooted it stated hard drive can’t be found fo3 error. I found the c drive has now become raw and I didn’t format this drive but the v drive as you had shown 😂. Anyways I ran a chkdsk command it fixed the c drive and I can see my c dir with everything ( don’t know what it has fixed as it wasn’t able to do log of it as message stated this. Anyways please tell me how can I get my system back. I have seen all videos and this has happened after a windows update that made my system get blue screen of death 💀. How can I install my windows ? 😔 as I don’t know the keys to this windows. Big mistake on my part 😢
Would be way cool for a step by step video on dual booting, and how to witch operating systems from WITHIN each OS. So you choose the OS to be launched at the next boot from WITHIN whatever the current OS is (win/linux). Why? So you can do it remotely of course, without having to connect to the console directly or via remote KVM. And thanks for this one.
the only tutorial that worked! 1 year later. Thank you so much. I had issues with a power outage that occured on a hackintosh which totally ruined opencore and I wasn't able to boot into windows! Thank you so so so so much, subbed + liked
Yes, it's working, thank you. I was looking for a fix for 8 hours, nothing worked. I created Windows To Go with Rufus, and somehow that broke my bootloader. Nothing i've tried didn't seemed to work. Startup Repair could't repair it, both built in and from Windows Installation Media. Also Safe Mode option was missing, so i could't boot into Safe Mode. Your method totally worked. I have also used V: for the UEFI partition, but in my case C: partition was not assigned also, there was C: partition, but it was my secondary D: drive. So i have assigned my Windows partition as P:, followed your instructions and voila, Windows booted. To be honest, i didn't think it would work, i have tried bunch of stuff in cmd, none of them worked. You're the best, saved my ass. :D
A dual booting video would be appreciated. I added a drive from a previous system and didn't realize it had it's own efi partion. Windows is installed on one Linux the other and I'd like to clean things up.
In the same predicament, I want to remove the Linux drive and go back to single boot setup but then Windows doesn't boot when I remove the Linuix drive.
@@madtza you might be able to use gparted to carve out a 100MB partition on the end of your windows drive and use grub2 to put a new bootloader on that drive. I know grub2 will look for other operating system when it first configures. Hopefully we get a video on how to do it from windows.
The computer has an all black screen with the company logo, that says, preparing automatic repair. But, it's been this way now for 2 days. Going into the BIO and changing the setting to allow the USB, Windows 11 Installation Media drive won't work. The computer won't accept/ find the USB.
Your video just made my day! I mistakingly deleted the bootloader for Windows when moving between my MacOS drive on my custom build. I thought I was going to have to reformat but your video saved the day! I'm back in Windows and I am definitely cloning / backing up my bootloader from now on. Thanks!
@@CyberCPU I'm not sure if this is the right place but I do have a general question. Windows 10 is booting on my main M.2. drive. I have a second M.2. drive for MacOS. Currently in MacOS I have to leave the flash drive plugged in to boot into Mac. Any idea how to have my system recognize the second drive with MacOS as a bootable drive rather than having to boot from the flash drive? Thanks again!
Excellent video. This worked for me, thank god. Something to add, if you're a Lenovo IdeaPad user and this issue occurs after cloning your SSD to a bigger drive: If you try to follow these steps, you'll see that your C drive is MISSING in diskpart. Don't panic. Boot into UEFI BIOS, and disable "Intel Controller VMD"; save and exit, then boot from Windows bootable drive. NOW, if you follow CyberCPU's steps, you should see your C drive as Disk 0, and you can proceed. IMPORTANT: after you're done with these steps, you might get a different blue screen with the ;( face. Just restart into BIOS again and re-enable Intel Controller VMD, save and exit. Voila.
I'm subscribing to a channel for the first time in 5 years because this video saved me from having a mental breakdown from a failed NVMe clone upgrade. My NVMe booted initially after the clone, then decided to break after I wiped the old NVMe and installed Pop_OS on it. Spent 5 hours total troubleshooting and trying different routes (the bootrec commands, regular windows boot recovery in the gui, macrium reflect rescue tool, etc) and all I had to do was format the UEFI partition and run a command to rebuild it THANK YOU SO MUCH FOR THIS VIDEO YOU SAVED MY SANITY
No help for me here. I installed the latest windows update on my ASUS GL512 last week. I rebooted after the update was complete. Getting ready for a trip of a few months very soon. Gotta get everything working & updated you know. Anyways the computer rebooted, rebooted etc. Strornvme Failed. I tried everything. Going thru all the steps and then some. End result I do a dir on the drive, No Files Listed, nadda, zip. Just nothing there. I take out the SSD and put it into one of those thingee's where you can plug it into another computer, it comes up as F: drive, I see all the files are there. Don't dare to try anything to this drive at this point with this computer because it is beyond my know-how as to what to manipulate on the drive to fix it. Anyhow, stuck it back in the laptop. But when I do the diskpart, list disk, only Disk 1 which is 19gb-0-free & nothing for Dyn & GPT. However when entering sel disk 0, there it is 1825gb status , healthy. i got up to the part where your going to delete the BCD. I switch to drive C & do a DIR, Volume in drive C is OS, and the serial number. Directory of C:\ File Not Found.
Thanks a lot for this very clear demonstration. It's very easy to understand you due to your attentive comments. I finally can boot windows 11 on my new SSD 🎉 And it was so exciting to use the command line that wake me app to learn it's functionality further! Thanks for all your attentive help ❤
If only i could donate to you my good sir! You saved my phd... The very fact that most people who come here are in a state of panic and you manage to confort them even before they fixed the problem with tour confident tone tell a lot about you. Thank you
Speaking from personal experience, I've run into Kernel-Power 41 issues in the past. The main issue is that there isn't just one solid reason this can happen. One PC that I worked on had a single faulty RAM chip, another one had a faulty GPU, both of which with the same code. Kernel-Power 41 is a very ambiguous error code, I'd look into the hardware to see what may be causing it, with programs like MemTest86 or OCCT just to name two, both of which have helped me narrow things down in the past.
That's going to be typically a hardware issue. It essentially just means that the computer shut down unexpectedly. I would start with how your computer is getting power. Make sure you're not using an ancient power strip or a UPS with a bad battery. If you're using a UPS you can test it by unplugging it from the wall and if it keeps the system running it should be fine. However if the system immediately shuts down when you unplug it then you probably need a new UPS or to replace the battery in your old one. Most of the time though this problem is going to come from a bad power supply.
@@CyberCPU I got my laptop about 2 years ago (it's a Lenovo ideapad3) so it's probably not using any ancient stuff. Also instead of shutting down or anything, it just freezes and sometimes even restarts on its own. And when it doesn't, I'm still able to close it by the power button. This means that some drivers ARE able to run even after this. And this mostly happens when I open it after I put it to sleep mode or hibernation. EDIT: There's actually some problems with the RAM recently (can use only 3GB out of 8), although it appeared way later the Kernel-Power issue occured. Could it be related?
Almost every how to on the internet is outdated with methods that don't work anymore. It's really frustrating. Now that mines out there, hopefully it will save people some time.
Because the operating system for a cell phone is custom built for that one piece of hardware. An operating system for a notebook is created for millions of different hardware configurations.
Perfectly? 😂 You probably mean better. Even system that build for only 1 hardware configuration (apple, playstation, x box) manage to have constant bugs. Maybe bugs are usually not critical, but definitely not perfectly.
no electronic works perfectly w no problems lol. A cell phone IS a pc. It’s just alot weaker of a pc that’s built for a custom os as somebody else said.
thank you for this! installed two os in two hdds and one does not want to boot up when the other hdd is disconnected. just followed your video and now it works!
This video is exceptional and provides the only clear explanation for rebuilding a UEFI partition. Many partition management tools do not offer this information, even at a premium price. Thank you for your invaluable assistance-you may have saved not just my day, but potentially future generations!
i followed most of the steps and i got stuck half way when i did format v: fs:fat32 it started installing something however thats not what happend in your computer i would like you to help me finish this off please it would be a waste off time since i got lost half way
After I type /fs:fat32 and Y it says “cannot format. This volume is write protected. Format failed” On a Samsung 970 evo ssd and msi Z590 Wi-Fi CEC motherboard. Can anyone help?
Hey I'm facing some problem with my PC it does not want boot at all and it keeps on taking me to the blue screen and telling me that automatic fixing is not done or something so could you make a video explaining and showing causes and solutions to it so it might help because I want to fix my PC with out deleting all my PC and starting fresh again
I get to the point of formatting the v drive which was created, but then I get an error message "Cannot Format. This volume is write protected. Format failed. How do I get around this?? thanks for your help, it's greatly appreciated!
Thank you so much! You're a life saver. I accidentally deleted my boot partition by reformatting my old drive after cloning. Your direct and simple steps helped me recover my boot partition. Thanks again!
I've just upgraded my disk from MBR to GPT and it kept telling me that a specific bootloader file was corrupt. This method really made wonders. Thanks a lot man!
Thank you so much! I botched an ubuntu uninstall, and this saved me SO much time!! Honestly thought I was gonna have to fresh install windows, but you saved the day!
You really saved my ass today and I can't thank you enough for that. There are no words to describe the sense of relief I felt seeing my PC finally boot to Windows.
I’ve watched like 25 videos on this topic, I have error 0xc000000e after migrating C drive to new larger SSD. I was over confident because it was booting up just fine until I completely cleared the original C drive I copied from. This video is amazing, I’m sure there has been a bunch of people finding themselves in this same situation. Thank you sir.
LIFESAVER!!! Is an understatement! You just saved me weeks of pain and agony trying to fix my windows boot manager disappearing after installing Ubuntu, and I wasn't able to boot into Windows. Thank you! thank you! You are a star!!!
I thought I was going to have to format my pc and lose a bunch of files. Normally boot problems I’ve had in the past were solved by the simple one click boot repair on the windows USB but this time you saved my pc, thanks man!
it did not work for me because on the last step ( I am referirng to the step where I am in V:\EFI\Microsoft\Boot\>bcdedit ) I get this message " The boot configuration data store could not be opened. The system can not find the file specified." Every other step looked exactly like your , just the last step does not work for me. I also have to mention I got into this problem after a failed BIOS update.
Thanks a ton. Without this tutorial i would have gone mad. I just cloned my SSD and my pc was not booting up and I was loosing hope of getting it booted. Amazing
Can this only be done through USB? I still have the ability to get to windows repair. Can I do it without going through a USB drive? Reason I ask when I get to the point of formatting the v: drive I created it says it is write protected and can’t be formatted?
Dear Bro, I have watched many videos on this subject but most of them gave only the commands to be executed and get the booting process ok, but you are the only person who have unpacked each and evey single step explaining what we are doing and then rebuilding the process to the original position. Thank u and May Jesus bless u abundantly.
I was struggling with a BIOS that supposedly could boot either MBR or UEFI, but really only booted reliably with a UEFI installation. This made me want to learn more about the bootloader. I really like the practice of making a backup of these kind of files, before there's a problem. I also like to enable Regback (as I learned from you), for the same reason. And here I am getting schooled. Knowledge really is power.
After hours and hours of trying myself and reading dozens of manuals which did not work, I finally discovered your video which solved my problem within minutes! Thank you so much for posting this!
Hi! I've just viewed your video on repairing the UEFI. Thanks!!! Bookmarking it in case I ever need it. However, I do have one question... At the point where you've recreated the UEFI partition (in your example, v:), and the system starts using the generic bcd file, why did you NOT import the bcd.bk file that you previously created? Wouldn't that have been easier than running a Windows Upgrade as you suggested? Am I missing some crucial point? Thanks again for all your great videos! Clem
You just saved me a lot of headache booting my Dell after I messed up backed up image upload through AOMEI when something went wrong, got my new install up and running, but!, I had 2 boot loader options at startup, one fresh and second corrupted. Great video! Liked & Subscribed
saved my day!! thanks alot! I should you have checked this video first. Spent 4 hrs wasting time on articles but none worked. Finally checked your video at around 1 AM midnight and it fixed in 5 min. Thanks a ton!!!
I followed your windows drive Clone guide, and had an MBR error when the coming was finished! Trying to boot the new drive, it wouldn't boot, so I followed this guide, and recreated UEFI Boot and now it's working :)
This really helped me. This problem occurred after I installed ubuntu on a second hard drive, then windows stopped booting from first hard drive. In my case bcdedit command was not working. Nonetheless I followed all the steps. I had the Ubuntu and Boot in the EFI directory. Instead of wiping the UEFI partition, I used the bcdboot command as mentioned in video. This recreated the Microsoft in the EFI directory. I am now able to dual boot into windows and ubuntu. I just have to reorder the boot sequence of the drive at startup. Thank you.
hey man, I've been having this problem since 2 days and I couldn't use my pc as I wanted. I've searched hours long for forums and other videos, but sincerely your 19 minute video helped me out to fix it completely!!!!
This solved it for me! Accidentally overwrote uefi partition when I forgot to disconnect the C drive before installing windows to a new drive. Searched a lot for a solution but it was all mostly unrelated. This was a simple and easy solution. Earn a sub and I'll definetly search your videos next time I have a problem.
Can't even express how many times your videos have helped me when im messing around with computers and corrupting or messing up windows files haha thanks man!
I'm so glad you speak English.
Sounds like you’ve been all over RUclips searching this topic as well. lol
😂 💯!!
Apparently Windows problems are way more common in India.
I have been working to fix this problem for 6 months! As you said, other online solutions did not solve it. Thank you.
Did you lose data?
Did you find the solution
@@YuvrajSingh-zq6cv yea, i tried to restore then it worked. Data didn't got deleted
6 months with corrupt boot loader? Are you ok? 😂
I got 5 month I'm going to try this guide
Thanks a lot. UFEI and boot failures are just scary especially when you don't have absolutely everything backed up.
You're such a great resource and your explanations are so good and straightforward.
I just got a new 7945HX laptop and I've heard that you should not update the BIOS when asked; so I need to sort that but just love this processor (CB=34800!).
Thanks for all you do! It is nice to have someone that has your back when you are in PC-Hell...
in my experience all windows systems are faulty and conflicts in software and problems with registry (by too much install deleting and then installing again the same software). theres always some f... issue and the fastest solution is re-installing Windows instead of searching for a needle in a haystack. I loose more time trying to find a solution unless the solution is obvious! so many hours wasted no thanks new install keep the old files no need to back up because theyr always on an another partition. 😊
@@omerdama1713wait how do you keep your data?
@@jDurMC Windows 10 installation media has an option to reinstall Windows without losing your files or settings, but I honestly don't trust it to actually work as advertised. Once I have a full backup of the drive I almost lost which brought me to this video I might screw around and see if I do genuinely keep all my work programs, games, and personal files, but not until I have that backup.
So I definately was in a state where I could not boot into windows and man am I thankful for you taking one for the team and making this tutorial. You both taught me something new and walked me through a process I thought I was gonna be stuck in forever. I am am seriously so thankful. Will be watching more videos to see what else I can learn since I have a new PC I plan to build this year.
SO GLAD that I've found this video instead of those crappy tutorials on google that just are adverts for shady boot programs for USB drives. It actually helped me and let me understand what was the problem in the first place. Giga props
Wish I had seen this first, Google is useless.
feel the same way, this guy is genious. Thank you
I’ve been building and working on windows pc’s for years! I cannot tell you how many times I’ve had to fix peoples systems who have ruined their boot files. Every time I painfully followed a tutorial, hoping it would be the last time I’ll tell you this after watching this I got it down pat and I’ve even tested it!!!Thank you so much.!
Outstanding content and delivery. As an old DJ, I want to compliment you on your voice, tone and delivery. I really enjoyed the video and would enjoy one on MBR restore as well. Thanks
The reason LIST VOL showed the USB drive is because VOL is independant from the selected disk, and shows all volumes on the system. You did not do it wrong, however it was not necessary to select the disk when you are using the volumes as a reference. If you do select the disk, LIST PART is more accurate as it will show the partitions on the selected disk. Both will give you the same results, but just wanted to let you know that you do not need to select the disk if you are going to select the volume rather than the partition.
Thanks for the comment.

THIS IS WHAT I'M FUCKING SAYING
THANK YOU THANK YOU THANK YOU for making this video!!!!!! WE fixed the bootloader after my 10 year old Daughter corrupt it by accident. I was a little bit upset at first, however I told her we are going to fix it together. After looking around on youtube, I came accross your video showing how to fix the bootloader UEFI Partition. After watching the video together many many times we started the process of executing the dos commands. Once all of the commands where done setup by step and the computer was turned off. I let my Daughter have the honnor of pressing the poweron button on the computer as we held our breath, windows booted up :) thanks again for making your videos for all of us to learn and enjoy them :)
With a few slight modifications to what you did because my situation was a little different I was able to get Windows back up and running, I really appreciate this video!
Man! i was stuck for eight hours trying to fix this. The ONLY thing you missed was you has to also map your windows partition drive letter and use it in the line to recreate the UFI.... You are a Genius!!!!
How do we map the windows partition drive letter?
@@fjose8712 It is one of the commands. You just have to pick an unused drive letter I believe.
A definite as answer? When type bcdedit says can't open requests system cannot be found
Dude YATB!!!! You are incredible, my desktop would not boot up from my m.2 drive. I thought I was toast, but thanks to your video I am now back in business. This will sound made up, but I literally spent 2 days and countless hours trying to clone my M.2 drive to an SSD because I did not think my motherboard supported an m.2 boot. I am embarrassed to say I went out and bought a new motherboard, new memory, new cooler, etc. and rebuilt my PC, still did not work. I worked on this since 2am and could not get it to work, went to bed and woke up and started another Clone software. it was running from the am until 7:30 pm with 23% complete before I found your video. Thank you, thank you, thank you!
I'm pretty much exactly where you were! so many new parts, so much time, so sad and frustrating! Had micro-center build a $3,600 computer for my son. For 3 months it worked well, for the last 3 months it's consumed more time and another $650-$700.
If this doesn't fix it my head will explode. . . 🤞
So refreshing to get decent instruction on EFI, boot, and navigating to a fix! You've saved me hours - thanks!
Glad it helped!
Thank you so much for this video. I stupidly deleted the bootloader using the AOMEI partition tool without understanding. After restart saw a black screen with "reboot and select proper boot device or insert boot media in selected boot device and press a key issue". Frantically was looking for an online solution (which also included clean installed that failed) for hours and came across your video. Just with faith, tried your guide and it fixed the corrupted boot. Didn't lose any personal data as it was a new machine I was tinker.
I would have been completely lost without your video! Thank you so much for this. I appreciate you explaining the steps instead of just moving through them. I work with subject matter experts every day and you're a really great educator on top of knowing your stuff. Those two things don't often go hand in hand. kudos
What was the problem you were facing
Was it that when you choose a boot device it brings you back to the UEFI menu ?

Excellent tutorial. I would appreciate seeing a tutorial for MBR partitions. Thanks again.
Read my comment above (5/14/23) for a possible fix for you.
Just reformat the drive and re install.
An interesting thing to know is that you can create a virtual drive (VHD) and boot from this in the bcdboot database. This is a great way to 'dual boot' if you want two copies of Windows (one being a sandbox) or to tinker on a system without affecting the main system.
you seem like you know what your doing so i would like to ask for your help
in the middle of the video when i did V: /fs:fat32 it started installing something thats not what happend to the guy who made the video however do you know how to help me in that case?
@@dragn7198same here
A month ago after a Windows update on my Dell XPS, the computer went into a constant cycle of restarting once the Dell logo appeared. I researched the issue, tried different solutions offered on forums to include repairing and resetting the computer, and nothing worked. The other day I spent an hour on the phone with Dell support in India who I could barely understand, and none of their solutions worked. They sent an email suggesting to reset the PC, which I'd already tried and which failed due to problems with boot files, and that didn't work. Although they said to reply with any issues and they said they were there to help, they ignored me after I responded. Frustrated, I watched your 20 minute video and voila, my PC works again - and it works without me having lost any of my data!
Thanks a lot!
You are genuinely a life saver. I had to take a few extra steps because my boot drive wasn’t appearing on diskpart, so if anyone is also having that problem:
1) Download some Intel RST drivers and load them onto that USB drive
2) Instead of selecting repair, select install windows to go to the drive selection screen (won’t actually be reinstalling it)
3) Load the drivers. The boot drive should now show up both in the drive selection screen and on diskpart.
4) hit shift + f10 to bring up the cmd prompt and go from there
Congratulations for this vídeo! I had tried several others ways to fix the "Windows dont boot after SSD upgrade" issue and it was the only one that solved it!
Thanks a lot! Para la gente que hable en español: Este es el mejor tutorial que he encontrado, funciona correctamente, lo pueden seguir casi al pie de la letra sin entender inglés, salvo en la parte en la que tienen que elegir la partición de UEFI, pero ahí lo único que deben tener en cuenta es que es la participación de 100 megas
Lifesaver! I was meshing around with another Windows installation and suddenly my main bootloader was screwed. This video helped a lot to get it back. Thanks man!
same here, i hope this works for me !!
LIFESAVER!!! Mission critical system, with failure after a SSD drive upgrade via clone. Would not boot afterwards, was about to panic until I found your video. I followed your instructions, which did EXACTLY what you said it would, thus saving time and money, avoided downtime, and probably saved my job!
Props to you, if only more guides were done with the same level of quality, we might actually fix our issues faster!

There are many videos for Legacy boot. Few people know about UEFI. Thank you, you helped me a lot! I am grateful to you
At last, someone who actually managed to explain this procedure correctly (fixing a broken ESP), and didn't omit any important steps.
THANK YOU!!! This was an absolute life saver. After 10+ hours of googleing and attempting other fixes on youtube, this FINALLY did the trick. I had my reservations as i was unable to back my machine up. I was able to manually back up my user files using cmd, but that was about as "backed up" as i could get, so had no choice but to take the risk in the formatting. I had few slight differences, but for the most part, everything worked the same. Only thing i couldnt then work out was at the very end when you mentioned using the USB stick again and upgrading the pc. Thank you again, cant express my gratitude enough.
You don't use the USB stick again. You run the Media creation tool and select "Upgrade" instead of creating a recovery USB.
Great video. I actually tried a few years ago to fix a system under w7 that had a corrupted boot/os and was never able to. The problem there was that when windows was updating or fixing an issue there was a power failure just during the boot screen, and it messed everything; it only loaded an error screen and not even boot options. Can't remember if it had a MBR or what, but I am glad to know that there are easyier methods to fix this for w10 or w11.
Windows 7 would have been MBR. UEFI was supported in Windows 7 but it was very rare to see a system using it.
Hello my friend, can you please help me? My laptop just died during startup because it had very low battery. Now it keeps going to bios screen and Windows doesn't load. Would this video help me?

This video is just about how to fix a non booting BCD. However it does not show how to restore or recreate the recovery console (installed in its own partition, usually at end of disk just after the normal windows partition). In some cases Windows image updates will not run if:
- (1) the ESP/EFI partition is full, i.e. too small to fit the bootloader, the "BCD" file, and various admin tools that have been placed there, or alternate bootloaders if you have installed "dualboot" for loading a Linux, which installs its own EFI tools there (like a Linux "Grub" boot loader), or other tools (like some offline backup system solutions, or offline antivirus, or offline defragmenters, or offlien hardware diagnostic tools specific to your machine).
- (2) the updated recovery console cannot fit in the existing recovery partition: Windows will then try reducing the Windwos partition at end, to make space for a newer version, but will leave the existing windows recovery partition there (the Windows recovery console partition is a standard NTFS partition, it is just formatted with a flag that "hides" it during normal boot, and avoids mounting it with a drive letter, but you can perfectly mount it using diskpart and see its content: it may be corrupted in which case the recovery console will crash or will not load)
Recreating the recovery partition is still possible; and you can also delete it using "diskpart" and delete superflous old recovery partitions that sometimes cumulate uselessly on disk. But it requires having a copy of it: you have to know how to manage partitions and recreate it with a sufficient size (usually about 655MB, its actual sizes changes a bit when it is updated when installing or updating windows, so in doubt you can give it a little more space such as 700MB). Just make sure you place this recovery partition immediately after the windows partition (which can be reduced using "diskpart" to leave a sufficient free space after it, just before creating a NTFS partition of 700MB, then assigning it the type GUID "de94bba4-06d1-4d40-a16a-bfd50179d6ac", and the GPT attributes "0X8000000000000001"
But creatign that partition is not enough, you need tor restore its content, and for that you must first mount it and assign a temporary driver letter for it (e.g. you can use diskpart, select the 650MB..700MB NTFS volume you created for it, and then "ASSIGN LETTER=R" before exiting diskparty Then you need a directory named "\Recovery"; if the "R:" is the drive letter you chose to mount, the normal file attributes for the Recovery partition is "ATTRIB /D R:\Recovery +s +h +i",you can see its effective attributes with "R:" to select the drive, CD "\" to go the root folder, then "ATTRIB /D" to list all files and directories in that root folder, you should see this line
SH I R:\Recovery
in addition to another line for the hidden "System Volume Information" directory, whose content does not matter, but that Windows creates to store some diagnostic logs (e.g for CHKDSK) or some additional copies of critical data (e.g. Bitlocker account access tokens and signatures, Azure account keys, encryption keys...)
The content needed of this Recovery folder is just another hidden directory named "WindowsRE", which has the same "+S +H +I" file attributes. Inside it there are just 3 files: "boot.sdi", "ReAgent.xml" and "winre.wim" (they also have the same "+S +H +I" file attributes, to hide by default in Windows Explorer), with sizes about 3MB and 555MB respectively. The "ReAgent.xml" file is very small, but cannot be copied from one PC to another, as it is specific to the partition layout on our disk: it is created using a command line tool name "Reagentc", which checks its validity with the BCD entries that you can control it and the EFI BIOS will use to boot in that recovery console, after checking that it is not corrupted and matches the digital signatures stored in the BCD for the "boot.sdi" file, which then load the "reagent.xml" to check it, and locate the "winre.wim" and check also its security signature: "winre.wim" contains a windows image with the signed Windows PE kernel, a few signed critical drivers, the recovery environment with some .EXE, .DLL for a few command tools you can use in the console and the default Wnidwos diagnostic tools and restore tools).
So you need a safe copy of "boot.sdi" and "winre.wim" (they are unfortunately not visible in the Windows ISO image: either you can use a copy from another Windows 10 or Windows 11 installation with the same x86, AMD64 or ARM64 architecture;, or you need to extract them from the windows image in the mounted ISO, by using DISM tool to mount the windows image in a temporary folder; there are some tools that allow to inspect what is in .wim or .esd windows images that are found in Windows ISO files).
Once you have restore the 2 files in "R:Recovery\WindowsRE", you must use BCDEDIT to cleanup old nonworking BCD entries, and REAGENTC to restore the BCD entry allowing to boot the WinRE console. Note that when booting from a bootable Windows setup DVD or flash drive, there's no tools proposed to do all this easily: the setup program just proposes you to reinstall windows, there's still no option to just reinstall the recovery partition and restore its working entry in the BCD; the only tool proposed does not even help restoring a working BCD if windows is not booting; that is stupid from Microsoft! But some non-Microsoft emergency disks exist that can do that for you (including from various antivitus/antirootkit third party solutions, or from third backup tools) without having to understand the tricky commands to correctly create and identify partitions in "DISKPART", "BCDEDIT" and "REAGENTC", plus other security attributes you need to check and make all this in the correct order...
If all is done correctly, there's a final step to check that the recovery console is now correctly setup: "REAGENTC /INFO" will show if is correctly installed and enabled. As long as this command does not show enabled, there's a problem: there are missing or incorrect files in the recovery console setup, or incorrect data in the BCD entry shown with "BCDEDIT /enum all", where you need to look at an entry with a long GUID matching what REAGENTC shows (but not the REAGENTC shows the GUID without surrounding them in "{braces}", whereas BCDEDIT needs this braces! How Microsoft can be so incoherent in the syntax of its command line tools!)
Note however that even if you don't have a reconvert partition, nothing forbids you from using an external recovery, such as a bootable windows installer on a flash USB drive, which includes the recovery tool.

I had a dual boot setup with Linux on one disk and Windows on another. I cloned my windows drive to a larger drive, but it turned out my UEFI bootloader was on the linux disk. I just couldn't boot into Windows with the larger drive plugged in. I cloned the EFI partition from the linux drive onto the larger drive, then cloned the Windows partition onto the remaining space. Your video provided just what I needed to rebuild the bootloader so I could boot into Windows again. Thanks a million.
Thx for this video that I followed carefuly after a bad W10 update. Unfortunately I've got a new blue screen claiming :
"Your PC device needs to be repaired. The boot configuration data file doesn't contain valid information for an operating system.

"The operating system couldn't be loaded because the system registry file is missing or contains errors

Yes, please do an MBR repair video. I always encounter SOME systems with MBR.
Would be way cool for a step by step video on dual booting, and how to witch operating systems from WITHIN each OS. So you choose the OS to be launched at the next boot from WITHIN whatever the current OS is (win/linux). Why? So you can do it remotely of course, without having to connect to the console directly or via remote KVM. And thanks for this one.

Startup Repair could't repair it, both built in and from Windows Installation Media. Also Safe Mode option was missing, so i could't boot into Safe Mode. Your method totally worked. I have also used V: for the UEFI partition, but in my case C: partition was not assigned also, there was C: partition, but it was my secondary D: drive. So i have assigned my Windows partition as P:, followed your instructions and voila, Windows booted. To be honest, i didn't think it would work, i have tried bunch of stuff in cmd, none of them worked. You're the best, saved my ass. :D
Yes, I would like to See how to convert from MBR to UEFI. Thanks for the great Video
Already did that one.

@@CyberCPUhey i have a problem it says i have no volumes and also dont have the disk that you specified either
A dual booting video would be appreciated. I added a drive from a previous system and didn't realize it had it's own efi partion. Windows is installed on one Linux the other and I'd like to clean things up.
In the same predicament, I want to remove the Linux drive and go back to single boot setup but then Windows doesn't boot when I remove the Linuix drive.
@@madtza you might be able to use gparted to carve out a 100MB partition on the end of your windows drive and use grub2 to put a new bootloader on that drive. I know grub2 will look for other operating system when it first configures. Hopefully we get a video on how to do it from windows.
The computer has an all black screen with the company logo, that says, preparing automatic repair. But, it's been this way now for 2 days. Going into the BIO and changing the setting to allow the USB, Windows 11 Installation Media drive won't work. The computer won't accept/ find the USB.
Your video just made my day! I mistakingly deleted the bootloader for Windows when moving between my MacOS drive on my custom build. I thought I was going to have to reformat but your video saved the day! I'm back in Windows and I am definitely cloning / backing up my bootloader from now on. Thanks!
Glad it helped.
@@CyberCPU I'm not sure if this is the right place but I do have a general question. Windows 10 is booting on my main M.2. drive. I have a second M.2. drive for MacOS. Currently in MacOS I have to leave the flash drive plugged in to boot into Mac. Any idea how to have my system recognize the second drive with MacOS as a bootable drive rather than having to boot from the flash drive?
Thanks again!
Thanks for the great video. This brought back a laptop from the edge of a complete rebuild. Great demo of the process, and explanation along the way.
Is this for when bios opens instead of windows?
Thank you for the great UEFI lesson and for pointing out the downsides
Thank you, thank you, thank you for saving my bacon!
Excellent video. This worked for me, thank god.
Something to add, if you're a Lenovo IdeaPad user and this issue occurs after cloning your SSD to a bigger drive:
If you try to follow these steps, you'll see that your C drive is MISSING in diskpart. Don't panic. Boot into UEFI BIOS, and disable "Intel Controller VMD"; save and exit, then boot from Windows bootable drive. NOW, if you follow CyberCPU's steps, you should see your C drive as Disk 0, and you can proceed. IMPORTANT: after you're done with these steps, you might get a different blue screen with the ;( face. Just restart into BIOS again and re-enable Intel Controller VMD, save and exit. Voila.
I'm subscribing to a channel for the first time in 5 years because this video saved me from having a mental breakdown from a failed NVMe clone upgrade.
My NVMe booted initially after the clone, then decided to break after I wiped the old NVMe and installed Pop_OS on it.
Spent 5 hours total troubleshooting and trying different routes (the bootrec commands, regular windows boot recovery in the gui, macrium reflect rescue tool, etc)
and all I had to do was format the UEFI partition and run a command to rebuild it
THANK YOU SO MUCH FOR THIS VIDEO YOU SAVED MY SANITY
No help for me here. I installed the latest windows update on my ASUS GL512 last week. I rebooted after the update was complete. Getting ready for a trip of a few months very soon. Gotta get everything working & updated you know. Anyways the computer rebooted, rebooted etc. Strornvme Failed. I tried everything. Going thru all the steps and then some. End result I do a dir on the drive, No Files Listed, nadda, zip. Just nothing there. I take out the SSD and put it into one of those thingee's where you can plug it into another computer, it comes up as F: drive, I see all the files are there. Don't dare to try anything to this drive at this point with this computer because it is beyond my know-how as to what to manipulate on the drive to fix it. Anyhow, stuck it back in the laptop. But when I do the diskpart, list disk, only Disk 1 which is 19gb-0-free & nothing for Dyn & GPT. However when entering sel disk 0, there it is 1825gb status , healthy. i got up to the part where your going to delete the BCD. I switch to drive C & do a DIR, Volume in drive C is OS, and the serial number. Directory of C:\ File Not Found.
Same with my Asus. Any possible fix?
Thanks a lot for this very clear demonstration. It's very easy to understand you due to your attentive comments. I finally can boot windows 11 on my new SSD 🎉 And it was so exciting to use the command line that wake me app to learn it's functionality further! Thanks for all your attentive help ❤
Yes, I do have a dual boot computer (Windows 10 and 11) so this could be useful.
@mda5003 If you already have dual boot win10/11, why would it be useful? In other words are you not happy with the outcome?
Can't believe this worked, I have tried so many other tutorials that rarely worked! Thank you !:)
If only i could donate to you my good sir! You saved my phd... The very fact that most people who come here are in a state of panic and you manage to confort them even before they fixed the problem with tour confident tone tell a lot about you. Thank you
Can you make a video on how to fix crashes and freezes due to an error referenced as "Kernel-Power 41" without a clean install?
Speaking from personal experience, I've run into Kernel-Power 41 issues in the past. The main issue is that there isn't just one solid reason this can happen. One PC that I worked on had a single faulty RAM chip, another one had a faulty GPU, both of which with the same code. Kernel-Power 41 is a very ambiguous error code, I'd look into the hardware to see what may be causing it, with programs like MemTest86 or OCCT just to name two, both of which have helped me narrow things down in the past.
That's going to be typically a hardware issue. It essentially just means that the computer shut down unexpectedly.
I would start with how your computer is getting power. Make sure you're not using an ancient power strip or a UPS with a bad battery.
If you're using a UPS you can test it by unplugging it from the wall and if it keeps the system running it should be fine. However if the system immediately shuts down when you unplug it then you probably need a new UPS or to replace the battery in your old one.
Most of the time though this problem is going to come from a bad power supply.
@@CyberCPU I got my laptop about 2 years ago (it's a Lenovo ideapad3) so it's probably not using any ancient stuff. Also instead of shutting down or anything, it just freezes and sometimes even restarts on its own. And when it doesn't, I'm still able to close it by the power button. This means that some drivers ARE able to run even after this. And this mostly happens when I open it after I put it to sleep mode or hibernation.
EDIT: There's actually some problems with the RAM recently (can use only 3GB out of 8), although it appeared way later the Kernel-Power issue occured. Could it be related?
This could had saved me a couple of hours 1 year ago
I had to search a lot to fix that
Almost every how to on the internet is outdated with methods that don't work anymore. It's really frustrating. Now that mines out there, hopefully it will save people some time.
I'm just wondering why IT peeps still can't make laptops perfectly working like smartphones do.
Because the operating system for a cell phone is custom built for that one piece of hardware. An operating system for a notebook is created for millions of different hardware configurations.
Perfectly?
😂
You probably mean better.
Even system that build for only 1 hardware configuration (apple, playstation, x box) manage to have constant bugs.
Maybe bugs are usually not critical, but definitely not perfectly.
no electronic works perfectly w no problems lol. A cell phone IS a pc. It’s just alot weaker of a pc that’s built for a custom os as somebody else said.
@@myprogramming5500 yes, sorry. What I mean is they work better than a laptop, just like my Lenovo Yoga 7 that keeps having a problem booting. 🤦🏻♂️
@@BlazeSh0t yes, sorry. What I mean is they work better than a laptop, just like my Lenovo Yoga 7 that keeps having a problem booting. 🤦🏻♂️
thank you for this! installed two os in two hdds and one does not want to boot up when the other hdd is disconnected. just followed your video and now it works!
This video is exceptional and provides the only clear explanation for rebuilding a UEFI partition. Many partition management tools do not offer this information, even at a premium price. Thank you for your invaluable assistance-you may have saved not just my day, but potentially future generations!
Thanks, I use this guide all the time myself. It's definitely helpful.
i followed most of the steps and i got stuck half way when i did format v: fs:fat32 it started installing something however thats not what happend in your computer i would like you to help me finish this off please it would be a waste off time since i got lost half way
@@BrinsleyMorrisonfor some reason my disk isn’t showing up, can you help?
After I type /fs:fat32 and Y it says “cannot format. This volume is write protected. Format failed”
On a Samsung 970 evo ssd and msi Z590 Wi-Fi CEC motherboard. Can anyone help?
@@wooltrouserslover777 I’m using the same drive it wont let me format
@@BrinsleyMorrison still doesn’t work it says drive is protected can’t write on it
Hey I'm facing some problem with my PC it does not want boot at all and it keeps on taking me to the blue screen and telling me that automatic fixing is not done or something so could you make a video explaining and showing causes and solutions to it so it might help because I want to fix my PC with out deleting all my PC and starting fresh again
MBR partition video please and thank you sir.
Thanks for the input.
I LOVE YOU
Well thank you.
@CyberCPU Areeee yiuuu geyyyy?????
I get to the point of formatting the v drive which was created, but then I get an error message "Cannot Format. This volume is write protected. Format failed. How do I get around this?? thanks for your help, it's greatly appreciated!
Same problem.. How did you solve it?
do you solve the write protected problem?
Thank you so much! You're a life saver. I accidentally deleted my boot partition by reformatting my old drive after cloning. Your direct and simple steps helped me recover my boot partition. Thanks again!
I've just upgraded my disk from MBR to GPT and it kept telling me that a specific bootloader file was corrupt. This method really made wonders. Thanks a lot man!
Thank you so much! I botched an ubuntu uninstall, and this saved me SO much time!! Honestly thought I was gonna have to fresh install windows, but you saved the day!
You really saved my ass today and I can't thank you enough for that. There are no words to describe the sense of relief I felt seeing my PC finally boot to Windows.
I’ve watched like 25 videos on this topic, I have error 0xc000000e after migrating C drive to new larger SSD. I was over confident because it was booting up just fine until I completely cleared the original C drive I copied from. This video is amazing, I’m sure there has been a bunch of people finding themselves in this same situation. Thank you sir.
LIFESAVER!!! Is an understatement! You just saved me weeks of pain and agony trying to fix my windows boot manager disappearing after installing Ubuntu, and I wasn't able to boot into Windows. Thank you! thank you! You are a star!!!
I thought I was going to have to format my pc and lose a bunch of files. Normally boot problems I’ve had in the past were solved by the simple one click boot repair on the windows USB but this time you saved my pc, thanks man!
it did not work for me because on the last step ( I am referirng to the step where I am in V:\EFI\Microsoft\Boot\>bcdedit ) I get this message " The boot configuration data store could not be opened. The system can not find the file specified." Every other step looked exactly like your , just the last step does not work for me. I also have to mention I got into this problem after a failed BIOS update.
same
Thanks a ton. Without this tutorial i would have gone mad. I just cloned my SSD and my pc was not booting up and I was loosing hope of getting it booted. Amazing
Can this only be done through USB? I still have the ability to get to windows repair. Can I do it without going through a USB drive? Reason I ask when I get to the point of formatting the v: drive I created it says it is write protected and can’t be formatted?
Same problem.. How did you solve it?
Dear Bro, I have watched many videos on this subject but most of them gave only the commands to be executed and get the booting process ok, but you are the only person who have unpacked each and evey single step explaining what we are doing and then rebuilding the process to the original position. Thank u and May Jesus bless u abundantly.
I don’t really know what I did, but I follow your instructions step by step, and it worked. Thanks so much!
I was struggling with a BIOS that supposedly could boot either MBR or UEFI, but really only booted reliably with a UEFI installation. This made me want to learn more about the bootloader.
I really like the practice of making a backup of these kind of files, before there's a problem. I also like to enable Regback (as I learned from you), for the same reason.
And here I am getting schooled. Knowledge really is power.
After hours and hours of trying myself and reading dozens of manuals which did not work, I finally discovered your video which solved my problem within minutes! Thank you so much for posting this!
Hi! I've just viewed your video on repairing the UEFI. Thanks!!! Bookmarking it in case I ever need it. However, I do have one question... At the point where you've recreated the UEFI partition (in your example, v:), and the system starts using the generic bcd file, why did you NOT import the bcd.bk file that you previously created? Wouldn't that have been easier than running a Windows Upgrade as you suggested? Am I missing some crucial point?
Thanks again for all your great videos!
Clem
I just saved a HP Envy (owned by my friend's mom) that borked the BCD after an attempted update. You just earned a sub.
You just saved me a lot of headache booting my Dell after I messed up backed up image upload through AOMEI when something went wrong, got my new install up and running, but!, I had 2 boot loader options at startup, one fresh and second corrupted. Great video! Liked & Subscribed
saved my day!! thanks alot! I should you have checked this video first. Spent 4 hrs wasting time on articles but none worked. Finally checked your video at around 1 AM midnight and it fixed in 5 min. Thanks a ton!!!
I am soo happy that it actually works , Anyone reading this .. Go for it with patience it actually works well
I followed your windows drive Clone guide, and had an MBR error when the coming was finished! Trying to boot the new drive, it wouldn't boot, so I followed this guide, and recreated UEFI Boot and now it's working :)
This really helped me.
This problem occurred after I installed ubuntu on a second hard drive, then windows stopped booting from first hard drive.
In my case bcdedit command was not working.
Nonetheless I followed all the steps.
I had the Ubuntu and Boot in the EFI directory.
Instead of wiping the UEFI partition, I used the bcdboot command as mentioned in video.
This recreated the Microsoft in the EFI directory.
I am now able to dual boot into windows and ubuntu. I just have to reorder the boot sequence of the drive at startup.
Thank you.
hey man, I've been having this problem since 2 days and I couldn't use my pc as I wanted.
I've searched hours long for forums and other videos, but sincerely your 19 minute video helped me out to fix it completely!!!!
Thank you, this helped me a bunch. Accidently formatted my UEFI partition and had to use the media tool to get my startup working.
This solved it for me!
Accidentally overwrote uefi partition when I forgot to disconnect the C drive before installing windows to a new drive.
Searched a lot for a solution but it was all mostly unrelated. This was a simple and easy solution. Earn a sub and I'll definetly search your videos next time I have a problem.
Can't even express how many times your videos have helped me when im messing around with computers and corrupting or messing up windows files haha thanks man!
Glad my videos help.
What does it mean when the volume you want to format is write protected?
Same problem.. How did you solve it?
I ran DDU to reinstall a corrupt graphics driver and it corrupted my BCD. Your vid helped me fix it in less than 30 mins! Thank you.
