- This video will show you how to convert disk scheme from MBR to a GUID Partition Table GPT without losing data or reinstalling OS in windows 10 and windows 11 computers.
(Convert MBR to GPT for free bit.ly/3jUxhfC with EaseUS Partition Master Free software)

This method will allow you to switch firmware from Basic Input/Output System (BIOS) to Unified Extensible Firmware Interface (UEFI).
UEFI mode has many advantages over Legacy mode, such as secure boot, faster startup, bypassing MBR disk limit of a 2 Terabytes as maximum disk size with four primary partitions as maximum numbers, in addition, UEFI will allow you updating to or installing windows 11 in your computer.

• How to Repair Windows ...
IMPORTANT NOTES:
Before attempting to convert the disk to GPT, make sure that your computer supports UEFI because the conversion process can’t be reversed back without losing data.
Once the disk gets converted to GPT disk scheme, the BIOS firmware must be reconfigured to boot in UEFI mode.
Windows Recovery Environment should be enabled, so you can recover your system if you advanced into a trouble.
FIRST: How to check if your computer supports UEFI:
The List of hot keys to enter Boot Menu for different brands including laptops and desktops:
- Acer: F12, F9 or Esc.
- Asus: Esc. or F8
- Compaq: F9 or Esc.
- Dell: F12
- Fujitsu: F12
- Hp: Esc. or F9
- Lenovo: F12, F8, F10, Novo Button or Fn+F11
- MSI: F11
- Razer Blade: F12
- Samsung: F12 or F2
- Sony: Assist Button, Esc or F11
- Toshiba: F12
SECOND: How to check if your disk has a GPT or MBR:
THIRD: how to convert the disk into GPT:
Type CMD into search box
Right click on Command prompt and select, Run as administrator
Execute this command to convert the disk into GPT:
MBR2GPT /CONVERT /ALLOWFULLOS
If you are trying that from Windows Recovery Environment (WinRE) or preinstallation environments, you have to change the CMD path to System32 folder using this command:
CD /D D:\WINDOWS\SYSTEM32
Then execute the command without /ALLOWFULLOS option
Otherwise, the command will fail with this error message
MBR2GPT is Not Recognized as internal or external command.
If the conversion failed with this or another error message, “Disk layout validation failed for disk 0” then you have to check the followings:
The disk is currently having an MBR scheme
The Bitlocker is disabled on the disk.
There are no more than 3 primary partitions on the disk with at least 1-megabyte free space in all partitions
There is no any extended or logical partition on the disk
The system partition is set as active and contains valid BCD file
Execute LIST VOL to show available volumes
Select windows volume using this command:
SEL VOL 2
Type LIST PART then press Enter to show available partitions
Select the partition to be deleted using this command:
SEL PART 4
Delete the selected partition using this command:
DELETE PARTITION
Execute EXIT command to close the DISKPART
Press up arrow key from keyboard to explore previous commands, then execute MBR2GPT again to start conversion.
The conversion process completed successfully after removing the fourth partition, but failed to update the reagent.xml file with suggestion to manually disable and enable WinRE.
Now power off the computer to change BIOS settings.
FOURTH: How to change settings of BIOS firmware to boot in UEFI mode:
Power on the PC then Boot into BIOS menu as seen in first part of the video.
Navigate to Boot option and change Boot mode to UEFI.
Unlike the disk ordering in the boot list of MBR or legacy scheme, the GPT scheme has a new boot option called Windows Boot Manager.
You may need to change the SATA Controller mode to AHCI.
Navigate to Exit panel and click on Exit Saving Changes option to boot into windows.
The first boot will take longer time, so be patient.
To show deleted partition, right click on Start icon then select, Disk management.
Right click on Unallocated space and select, New Simple Volume option.
Change the Size of new Volume if you want, otherwise, click next to take all available size.
Change the assigned letter if you want, otherwise click on Next to continue.
Move the files and folders back to the new volume.

Man, the only person who tells us all the problems which prevent from verifying\converting and their solutions. Very helpful! Thank you!
This video was a life saver. Finallly since Windows 11 came out, my computer is ready for it! Before… mbr2gpt wouldn't make the conversion of my system disk and it turns out because of an extra partition. With the help of the video i could delete it and convert my system disk to gpt.
Thank you so much for your detailed feedback ❤️🌹❤️🌹
I converted with aomei partition assistant because diskpart is not working for system disk
AOMEI is not for free now
Bro, 2 months trying to change that option cuz i want to play valorant, you are the only one that do it, i love you, thank you for all
Glad I could help!

This is an informative tutorial, and I also fixed by converting from mbr to gpt with ao mei partition this one is nice.
Thank you for your tutorial, it worked well for me. Also aomei is nice to convert the disk.

can you help me with a question, can I move the os to ssd but leave the data on hdd?
This was quick and error free. I'm now finally installing Windows 11, thank you so much!
So I converted the disk and plan to move the os to ssd so I can boot from it and save other data on hdd, I cloned successfully with partition assistant.
To all people searching: THIS VIDEO WORKS. Thanks man you really helped me out here👍
Thank you for your feedback
This actually worked, this is amazing finally after alot of videos this video fixed everything thank youuuu so muchhhhhh
But delete partiton will cause data loss, ao mei partition will not cause data loss while converting.
I checked all 4 possible issues and everything is okay. Still getting the error :)
Same 😭
Please ans my question if I put this command after all the steps mbr2gpt /convert /allowfullows
It's showing invalid argument-/allowfullows
Please help me 😫😫
Very helpful. Thank you! 🙏
You're welcome!
A super helpful presentation. Thank you.
but it will not convert system disk for me, unlike aomei it's more useful
No lol. I converted my disk from MBR to GPT using Command prompt including system disk.
You guys are jealous no one buys your software, so stop commenting on RUclips saying aomei is best
Finally you solved my issue. Thank you
You are welcome!

oh my Gosh, Boss you're doing good work to guiding each and every steps of converting but luckily I've GPT so, Thanks for sharing your Incredible Knowledge .. Brilliant..
So nice of you
It worked for me thank you for detailed video
I only have 2 partitions in my disk and cannot get mbr2gpt to convert or even validate.
At this point I know my system is using BIOS legacy mode and has UEFI and secure boot available but do not want to start over from scratch with a fresh UEFI Windows install. This is such a pain.

My problem is solved by your idea, thankyou so much
You are most welcome.
I GET THE FOLLOWING ERROR - ValidateLayout: Dynamic volumes/Storage spaces are not supported.
Because your disk has a dynamic volume, so you can't convert without losing data.
@@ValiumMediaTech ah dam. That sucks
@@sandstorm7349 You can copy your important files to another disk, and then format the disk in GPT scheme if it is necessary.
@ValiumMediaTech okay cool, I'll look into it. Been thinking about upgrading my whole storage and drive system anyway so might be time now. Haha
Thanks for this video but I wanna ask that I have one hard disk too so can I convert that hard drive to gpt by partion wizard software and convert c drive by this process is it ok????
You may not need to convert another disk that is not containing windows. However, if you can do that, you will loss all data inside that disk.
So I find that it's easier to convert with Aomei partition assistant not mbr2gpt and diskpart.
Nope, I don't trust Aomei.
CMD is better
Great help without error
thanks 😊
Really thank u man!!!
Well done thanks 🙏🙏🙏
Thanks and welcome
there is 250mb unallocated logical partition that is becoming primary when i try to create. i think it is not allowing to convert mbr to gpt.
i had converted mbr to gpt long ago but few days ago i changed it back to mbr but due to some limitation to mbr i am trying to convert back to gpt. but this partition is not allowing me to convert. i am using minitool partition wizard to modifying partitions.
So try the method from the video instead of using the mentioned tool.
For I have converted GPT to MBR using AOMEI partition tool after it got reboot and stuck in boot menu showing to add a bootpath
(previously I have some boot path now empty every time power on going to boot settings)
Sir pls help because it's not my lap. If data lost in it would be big problem
my SSD had only 2 system recovery and the main one should I delete the system partition
this video is well done, but please, please, use a human to do the speaking and drop the music
Thank you so much for This video..
You are so welcome!
How can I solve this problem

Hi sir, what to do if there is an "*" under Dynamic section in list disk option of cmd promt.. should i follow same steps??
Do you have more than one disk?
If anyone is getting the "Cannot create EFI system partition" error, try the "DISM /Online /Cleanup-Image /RestoreHealth" command. That fixed it for me.
I was also getting the "Cannot find room for the EFI system partition" error. After trying to shrink my C:\ drive in Disk Management, I've noticed that it can only be shrunk by 14MB. I then used MiniTool Partition Wizard to transfer 2GB from my D:\ drive to my C:\ drive, and that fixed the error.
it says cannot find room for the efi system partition
What if your new computer does not have legacy mode in the Bios and your old computer backup is MBR?
Convert the MBR disk to GBT in another computer and then connect it to your new computer.
Thank you it helped
i am having this error "Cannot find OS partition(s) for disk 0" , how to fix please
Make sure you have assigned a letter to all partitions if you are trying from Advanced Recovery.
Also rebuild the BCD as instructed on this video and then try again:
ruclips.net/video/oQcFjr6laeo/видео.html
But MBR2GPT wipes your entire drive, reformats it, so regardless you'd need to reinstall your operating system, I don't think I can risk this
Converting the disk scheme from MBR to GPT using MBR2GPT will not wipe anything.
in disk mangement i cannot see system reserved partition i think that why it keeps failing how to solve this
Restart your computer and it should appear if your system is GPT.
Hey man could you help me reset the conversion I did it without using a usb for the uefi my computer won’t boot up can someone help me just reset it please
Bhai thank you so so much
You are welcome
*cannot find room for the efi system partition* what could this error be?
Make sure you have enough free disk space on the cor windows partition.
THANK YOU!
Brother While Installing Windows 10 I Just Formatted C Drive Only Later In Installation Process The Error Occured MBR To GPT. I Just Tried The Porcess In Command Prompt Process Like - diskpart -> list -> select disk 0 -> clean -> exit. Later It Shows All Drives As One Un Allocated Space. Am I Lossed Total Drive Data? If Lossed How Can I Retrieve It. I Have Valuable Information In D Drive So Please Help Me Out From This Situation. Thanks
I don't know if you can retrieve your files or not, but you may need to consult a third party apps providers, such as Wondershare Data recovery or Easus Data recovery if they can recover your data.
So, don't try to do anything to the Unallocated Space (such as creating new partition or FORMATTING) until you get the final answer form the assistance of the mentioned companies.

After changing Bios I save and exit so the computer restarts as it should but instead of windows starting normally, it shows an image called "Boot Menu" and that's where I'm stuck. Every time I click on any of the boot option displayed under that Boot Menu nothing happens I just end up right back there on that boot menu.

i have many games in local disk d and i dont want them to be deleted but my local disk c is full what should i do
Move large files from the C to the D or to external storage (USB or Hard Disk), after that, convert the C into GPT.
The files inside the D partition will not be lost if you have followed the video correctly.
It says "cannot find os partitions for disk 1"
Execute this command and then try again:
bcdboot C:\Windows /s C:
I followed your tutorial and converted mbr to gpt partition on my hp g6 laptop.Conversation was successful, i manually enable secured boot and when restarting my laptop it failed to boot up showing error message no boot device found, please install an os on the hard disk .I am stuck so help me?
You have to change Boot mode to UEFI and to select Windows boot manager as the first boot device.
Add a photo for your Boot settings and upload it to drive.google.com
then post the link in new comment.
Same problem... Please help
Will this work on my gigabyte uefi duel bios h81m-s
When I type reagentc it tells me is not recognized as an internal or external
Pleas help
Change the CMD path to system32 folder as instructed on the video.
I did the same steps, but now i get an error that says media check fail.. And cant get into windows. Please help
If this happen after successful conversion of the disk to GPT, you have to change BIOS settings to UEFI as instructed on the video.
@@ValiumMediaTechi did change boot to uefi mode, but i cant boot to windows.
cant i delete recovery partition and make one right after i convert it to gpt
You can't delete recovery partition, as you can't complete the conversion steps without it.
Instead, you can delete the storage partition if you have, or you can delete the System partition (100mb) if you have a separated partition, but you should boot into recovery environment in order to delete the System partition.
Hi can you help me with my problem
I recently uninstalled my old hdd from the pc (doesn't contain windows in it)
And my pc doesn't want to show windows manager on my m.2 that has windows on it i can't boot into windows anymore with that ssd
I tried to install another m.2 with windows on it and it works just fine
I was using my pc normally until I removed that hard drive
What is the error message that appears when trying to boot your computer?
Can I delete that system reserved "D" drive which was automatically created while GPT conversion??
The System Reserved partition is already available before conversion but without letter, so it is not shown. After conversion, the System Reserved partition take a letter, hence it is appear in the partitions list. it's size about 100 mb.
So you can delete or keep it if you want.
@@ValiumMediaTech ok, I will keep it if its important, but can you please tell me if I can remove its drive letter in order to hide that drive??

What does it mean when it says cannot find OS partition for disk 0
Did you have more than one disk installed on your computer? If yes, your windows may be installed on the second disk, which will take the number "1" on the disks list instead of "0"
In this case, try the following command:
mbr2gpt /convert /DISK:1 /allowfullos
You may try to execute the following command and then try again:
BCDBOOT C:\WINDOWS
Could you please help me out here. I get an error while I tried to Format the current OS which is Win 10. By mistakenly, I have deleted the partition of C where win lays and other 2 partition got data. Now am stuck and tried to troubleshoot with my capacity. it turns out to be negative. non of them worked. I tried All BIOS things legacy mode and tried even making a new bootable USB too. Is there any way to reinstall the Win 10 with out loosing my data from D & F drive? Looking forward to hear a solution soon. It will be thankful if you could give some solution on this regards. Thanks.
Yes, you can reinstall windows 10 or even windows 11 without losing your data on D and F partitions. just create a bootable USB that is applicable to your Disk scheme and reinstall windows to C partition.

Convert the partition in which you are booting windows from, and the other partition will be concerted directly. But if you have 4 partitions or more, you will fail to do that until you remove one partition.
@@ValiumMediaTech 4 PRT , 1 (System, ACTIVE primary) , 2, primary , 3 primary , boot primary :(
