In my all my years using Windows, the Windows Recovery Partition has NEVER helped or worked right.
Same, only windows 7 worked for me but never anything else
I remember breaking my windows installation (windows 11) on my laptop and using the recovery partition but it didn't work :/
I had to reinstall via tiny 11
Hi, used your video from 2 years ago. How to repair startup (something like that). Worked great on Win 11. You were right, that the first instructions you gave are usually left out. Other guides did not work because of it. Great work.
I'll check this out, to be sure everything is set correctly.
Hey Chris, another great video tutorial, clear and highly educational, I am following Your work for more than two Yrs :)
This helped fix the dreaded win 10 update in jan 2024 for me! Thanks so much, was looking for a while and your video not only solved it, it covered enough edge case scenarios that when things went astray I was able to continue. I also learnt a lot along the way. Much appreciated :)
I tried to do it today…. Somehow my system deleted the windows RE image and cannot reenable or find the reagentc.exe.
Thanks Chris, I had to reconfigure this for a user yesterday due to a bad Windows update. I used a guide but have watched this video after for a better understanding.
Thank you for this info. I had found a bunch of other videos with people just doing the process and not explaining anything and i was getting pretty frustrated. but thanks to you i got it working!
Very well explained Chris, thanks!
Thank you a lot Chris , for this vidéo, U are a very good teacher 👌 A Frenchman, who loves your job! 🤙
Thanks. This finally solved all my issues arround WindowsRE. All infos in one video, great.
Very good guide, recently I have been looking into the GPT disk structures with a view to understand how to reconstruct the EFI,MSR & WinRE partitions from scratch on a fresh disk after restoring only the windows partition without 3rd party tools, DISM truly is a wonderful tool :) as long as you track the version of dism used to create the image, some times newer versions wont unpack older ones
which source can you recommend? My pc says: "is write protected" and I can't move forward
Can someone tells me if this procedure can help to tell windows 8.1 to choose A DIFFERENT RECOVERY PARTITION from an external USB hard drive ?? I made a recovery backup recovery point but in an external USB hard drive... I can see that the recovery point files are there (external USB drive) but no matter how hard I try windows does NOT want to recognize that recovery backup, and I mean I tried everysingle option in the recovery blue boot menu when you restart with SHIFT+RESTART , i wonder if this procedure can help me to enforce windows to recognize that USB recovery drive a the DEFAULT RECOVERY PARTITION, so it may see the recovery points in it (I can see files are there and many gigas), someone has any idea how to do it ??? Thanks in advance
@@abdoolsilva6398 try using the version that was in circulation when you created the backup.
Thank you for tis video, I could not run MBR2GPT to clone a customers drive from an old PC to a new one and you just saved me a ton of time trying to get this to work right
Thanks, you just reminded me to make a restore point
so clear chris.. thanks a lot... tried after partition clone... working
Renaming or (re)moving ReAgent.xml is crucial for this to work. Thanks for the guide!
Awesome video, thank you.
I never thought I would actually follow this tutorial, but I did since I actually really needed it 😅
I understand it now. Thank you!
Extremely good tutorial
Hey Chris, a video I think would be a neat one is going over different bootloaders, like comparing GRUB2 to rEFInd. I've been using rEFInd more on my laptops lately cause it detects all bootable media on each boot instead of having to add entries like in GRUB, so rather than mashing the button to get into my BIOS or Ventoy it's just there in the list. Also I think you can arguably make it look better with the theme support of it, though more limited selection than GRUB
Seconded
@@chromerims Thirded!
Most likely why mine doesnt work it's at the start not the end wooooooooooo but thank God for you man your video is the only one to help me fix this problem so far of not being able to enable the recovery, thank you so much went through like 18 vids
Very useful video!!!
At first i thought that ReAgentC was 3rd party software, but its actually built into Windows. I didn't know that, well thanks for showing it
The Recovery partition can also be the first partition on a gpt disk.
Btw, great video and explanation
YES!! I sure do miss the F8 boot option..
you can reactivate it with the bcdedit command
@Chris, you should make a video on what modifications would be need to make this recovery partition a custom image. That is something I would love to be able to have, if that is possible.
Thanks for the tutorial
You know your stuff. Good job. Helpfull.
WOW . Gracias !!
Very nice video
Jolly triumphant video 👍 Awesome channel.
15:51-18:19 --- Wonder why you did not click "See more recovery options" at the bottom? Therein, "System Image Recovery" is located.
Kind regards, neighbours and friends.
Nah the F8 option wasn't argumented for security...
It was argumented "Oh we optimized it so much now, that it boots so quickly that there isn't time to register the F8 key." back when the F8 menu disappeared.
On older windows 10 installations the recovery partition is at the start of the drive. The issue is that after somes updates over the years the recovery partition has grown in size so it doesn't fit. My PC has 2 recovery partitions. Nowadays windows attach the recovery partition at the end of the C:/ partition. After updates, if the recovery partition increases in size again it will expand towards the C:/ partition. The recovery partition is always after the C:/ partition.
In my case, I have C:, D: and E: drives. The recovery partition is after E:, at the end.
@@archishmannag Yeah, I forgot to mention that. Always run windows setup with a single drive plugged in if you want all windows partitions on a single drive. If you remove a drive for some reason in the future you won't have a recovery partition. I think it has to do with slave/master. The safest way is to add extra drives after installation.
@@loukaskollias8948 No, I said that wrong my bad. I have 3 partitions. And recovery partition is always at the end of all partitions. I used drives mistakenly.
@@archishmannag so your system drive has 3 partitions plus the recovery partition(4)
2 recovery partitions, and how can you tell windows which one to use as by Default in case you need to go back only to a specific recovery point ?? in my case I mad a back up of recovery in an external USB drive, I can see all the files are there but I don't know how to tell windows to see that USB recovery drive as the Default ? windows can not see those recovery points no matter what options I use in the blue recovery menu
4:17 This long string is just a correctly formatted Universally Unique Identifier (UUID)
Heyy really thanks to you dude, you help me to solved my problem which did not solved by anyone, And i was very upset and stressed due to this problem,,
Thank you sir really😊😊☺☺🙏🏻🙏🏻
Quick comment on the partition type, since it's GPT (GUID Partition Table), that looks to be a GUID format.
Just had to go this on a server, but luckily it was easy rebuild. I didn't see this process, though.
Great video tutorial, could you also share nt kernel commands at startup by pressing F10 where we used to use F8
Looking forward to the return of the F8 option.. Please let know when you make it avail. Thanks
I think is to reserve the best and fast space of the disc to the normal use
Startup Repair never worked for me either. I accepted that windows sometimes craps its pants so I usually just go for full reinstall, especially if it's not my system. Less effort than trying to figure out what went wrong and fix the damage.
And of course you have saved the customers data to another drive first? Then you also install/update the drivers in Windows as well all application the customer had installed?
Does bootrec /fixmbr, /fixboot, or /scanos still work in the recovery environment? 100% of the time I try to run them, I never get them to work. It might fixboot, but I get access denied for fixmbr, and it never finds an OS for scanos
Hi Chris, thanks for detail explanation, i have one question as im not good with scripts, just wanted to know how can i check the WinRE status from script and if it is disabled then how to enable it, as it is a pre-requisite for our bitlocker deployment so need to check the status on all devices and if it is not enable then we need to enable it. So cannot login and check on all devices.
Hey can some suggest if we can have this recovery drive at start of the disk ??
Like moving c drive forward, and cloning it to the before C drive ??
Hi Chris if the partitiom is missing how do you find what the guid should be?
hey mate love the video and has fixed a few issues I was having with a few of the other tutorials so thank you.
A question though. Everything seems to indicate this has worked however I am unable to see the advanced boot option in control panel | windows update | recovery option and am unable to use the shift restart method to boot into advanced mode. Also when I forced it to do this it was unable to find the recovery image. Would there be a reason for this?
I have 2 recoverypartitions on my system disk i dont know why. Is this a problem if there are 2? What would you do?
Wow. Windows takes something that should be 4 steps in a GUI - turn off recovery, delete partition, do whatever other disk work you need to, turn recovery back on - and turns it into a journey through powershell Mordor.
During a recent ssd upgrade everything went smooth but this recovery partition thing goes wrong in disk manager its is showing that i do have a recovery partition but while checking on cmd promte it is showing not available, all ways of restoring is too complicated including this so for now i am sticking to full image backup by macrium in case of any catastrophic.
DSIM also works using an image from the internet on a Microsoft server, using /online switch right? Sure it's useless if you don't have an internet connection but it's handy.
How did I get the recovery in front of the OS. ❓And one in the back.
Few weeks ago I swapped my mobo and used the same windows 11 pretty cool how win handles this but decided to go for a new setup...
After many months of use it a drill to reinstall clean and paragon15 is always the safeguard to me.
Your thumb drive install video is great but settings are prime to get them back.
OK how did I get that recovery partition in front and one in the back... MS writes how this layout works but many tech issues this layout as it wash in front of the OS...
Oh yeah I have a delay in the boot and my asus mobo is figuring out what to do and even doing a second POST.
Its possible to have the partition moved to the beginning of the drive I have done it before.
Hi man,
Do you know if i had a recovery partition that is 2 years old and inreset my PC
It will go back to 1909 build for example?
thank you very weel done. btw:would like to setup a realtime recovery ISO to boot to windows 11 / 10?
How do you rescue non boot systems. except chkdsk or sfc /scannow. Because sometimes systems don't want to format or etc.
Is there a way to prevent applications from saving window size and position in Windows? I want all apps to open in default window size and position.
Very cool. If I deleted the partition long ago and want to now recreate it... how do I know what to set the ID to that ends with "6ac"? Sorry if I missed it.
9:41
@@tactileslut thanks... I mistakenly thought he meant the we would need an ID with "6ac"... I guess he meant you need that exact ID he shows... I thought it would be unique to each partition. Ok Microsoft that really doesn't make any sense when the other IDs are 2 characters.
Hey Titus, I tried this and it worked fine. Except on next reboot file system of WinRE partition reverted back to raw and reagentc got disabled. What should I do? This happened twice, each time I tried.
I thought you were going to introduce some other great software tool available on the internet that actually is useful unlike winre. you hit the nail on the head when you mentioned startup repair working 1 percent of the time. I never had success on win10 with the only success being on win 7. Only thing that fixes hair pulling windows issues like missing wifi adapter is system restore, for me atleast. still using win10, hate windows 11 with a passion. hiren's bootcd is also a great winre iso that can be used to copy off your stuff on a failed windows installation
My, what a conundrum to go through for a recovery partition. And some people have the nerve to call Linux convoluted. 😂
Is there a way to get a new laptop that has a Recovery partition and EFI partition that is hidden and using drive letters that you need like E and F ?
Just downloaded Windows 10 again with the Micro$ Windows creation utility. The ISO created now has the Install.esd file and not install.wim. I mounted the Windows 10 ISO and then mounted the install.esd with PowerISO and extracted the winre.wim file that way.
what if i already have a recovery partition but needed more space? is diskpart neccessary? i notice i cant right click on the recovery partition but i can on the OS/main partition.
Question for anyone who can answer it. I want to assign a % to overprovisioning, can I do this to shrink C, and then re enable it (after the unallocated OP partition?)
Or even better! Can I move the recovery partition in front of the C drive (just to make sure I can mess with the OP partition down the line if I need to)
My SSD has recovery partition as the second partition, which makes changes to its size impossible without cloning the primary partition as a backup, resizing recovery, and then restoring the primary to a smaller size.
If you want to allocate left over hard disk space you don't need to specify size=x
I had always problem when using software for imaging windows drive on smaller disk, that it removed the recovery partition and it did not work becase of it.
Will try next time I will be moving system on smaller disk.
the install.wim does not exist in my iso file. I tried using the boot.wim and mounting the image. Though still does not come up. Any suggestions?
What the best Linux distro to try to repair a hard drive?
can you make a tutorial of this with windows pe?
This is weird, 0:52 I have the recovery partition at the beginning how do i get it allocated over there?
16:00 great video had this issue and didn't work but got help from microsft on quick assist and they could not solve it so I upgraded to windows 11 and now everything is fine IT IS A WINDOWS BIG ISSUE BUT YOU EXPLAINED IT VER WELL keeping this video on my colletion and your righ tha repair option is just a decoration 16:00
Win 10 Pro system. No recovery partition on the C boot drive. In Windows\System32\Recovery only the ReAgent.xml file is present.
Restart with shift pressed boots into the recovery mode so recovery seems to work without a recovery partition.
In the root directory of the C boot drive is also a folder called Recovery widge is not accesseble and is an empty folder according to windows Explorer.
But when examening this "empty folder" with a partition manager for instances Mini Partition Wizard all the recovery files are in it. (you can also copy this folder to the desktop and see the content with windows Explorer)
Actualy the ReAgent.xml file points to the "empty folder" on the boot drive.
I don't know if the boot drive Recovery folder is made when Windows is installed, never have payed attention to it or that it is made after my recently operation from MBR to GPT.
Bottomline: check your boot drive for this Recovery folder and if present you don't need a recovery partition.
If I remember correctly windows used to put the recovery before system reserve in the beginning of the drive years ago
My old laptop still does
When I did the listing on my disk1: which is whre C lives I saw 3 listed as system and 3 Recovery Partitions.
How to fix this for SFC scan Failure. "Windows Resource Protection could not perform the requested operation" . Running windows repair says it can't fix drive. Running DISM at winre admin console prompt says can't run in a PE environment. I trying to fix some SRM???.dll hash errors, and even though they restore from component store, they come back, also dual ownership of various directories? Even when running dism restorehealth at the console admin prompt when logged into windows will not correct any of this.
Moreover, just tried a reset PC, and it also says it can't reset the PC....
A second questions is: How to setup a reset PCc partition. When I run it, it seems to know where to go on the drive. The second computer has a PBR Image on a Dell laptop and OEM partitions. How can a recreate at the command prompt the reset pc, pbr image partitions and maybe the OEM partition which I think has win8.1 that came with the PC before the upgrade to win 10 home/pro
Had to Install 1809 by clean partition after not getting update. Then that would not update, and got no update to install. Finally got to a system that only had Windows security updates. And did things to try to repair the system the way Microsoft explained. Used Dism, and all that. I got ready to clean wipe the Partition and install 21h2. Suddenly 11/1/2022, Windows Update finds 21h2 and conpletes the update. HP 15, 15ac143wm 2015.
For some reason. Windows claims I have an “OEM” version of windows and windows wont allow me to downsize or increase the size of this partition.
I'm a senior attending Chris Tech University online. Correct me as required. Presently I have a hobbled Win 10 install that at some point will be upgraded to Win 11 after switching to UEFI. Firstly I need to get a laptop in case anything goes south. To the point what is the advantage to using a Recovery Partition vs a Bootable USB Thumb Drive? Is file recovery part of of the GUI Recover scheme. I run this periodically as it backups all files on the not just the Documents folder.

I tried to reset win 10 and it said it couldn't find the recovery partition... will that effect my windows key??? Actually it's embedded in the BIOS.. so, I guess it's ok.
does reset this pc recreate recovery partition?
Just boot winpe from a usb drive. Same thing. If you don’t want to create one yourself use hirens boot disk. Easy peasy
21:05 the file is not missing just they are hidden or you have deleted it to have more space.
Where is the link to the shirt? Edit: NVM, I have never seen the Store tab for channels prior to now.

No usable free extent could be found. It may be that there is insufficient
free space to create a partition at the specified size and offset. Specify
different size and offset values or don't specify either to create the
maximum sized partition. It may be that the disk is partitioned using the MBR disk
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).
The problem with the partition at the end of the drive is on Windows Server 2022... If you extend your drive, you cannot extend your C: partition because of the recovery partition.

It has everything to do with it
what 3rd party software that will do all this ? other than Acronis ? any freeware ?
