- Are you trying to upgrade your Windows 10 computer to Windows 11, but you need to convert your windows C drive from MBR to GPT and you don't want to lose any data for FREE! This is very easy to do. This will allow you to secure boot your PC and enable UEFI boot mode. When you open Command prompt, make sure to run as administrator and type this in with spaces.
mbr2gpt /validate /disk:0 /allowFullOS
mbr2gpt /convert /disk:0 /allowFullOS
If you don't have the MBR2GPT.EXE check out the microsoft website. ...

Thank you so much! This was quick and easy. I was reading so many articles before I finally found this video. At first I was worried I did something wrong because I already changed the settings to UEFI only in my BIOS but then I looked again, restarted and now I have GPT.
this won't work in cases where windows wasn't install with the uefi boot option the tutorial is not clear and if you have valuable information on your PC you should be careful
For me it worked fine. I had a Legacy bios. Of course any data you care about should always be backed up, and also: it's good to watch multiple tutorials before you make the decision. The legacy to UEFI bios change happens after you convert the disk not before. (Right?)
MBR2GPT: Attempting to validate disk 1
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
Disk layout validation failed for disk 1

One of the reasons could be that your disk is split in more than 3, I had 4 partitions and after I unified two of them it worked fine
Brilliant, worked for me. Spent hours trying to workout why my system wouldn’t reboot after changing the BIOS to UEFI, I didn’t know about the disk management side of things!
@@luis_laurent I had checked to see if my PC could upgrade to Win11 from Win10. I had to change the security settings in the BIOS,( Microsoft have a tool to se if you can upgrade the OS)however I couldn't. After researching, changing my HDD from MBR to GPT was the problem. After following the instructions in the video I went into the BIOS again and was able to change the security settings with no problem. I hope that helps you. Regards.
It worked great for me! One machine had 2 recovery partitions that I had to remove before the mbr2gpt would run. The other worked perfectly! After struggling with the issue of not being able to boot to windows and then finding out in some MB you have to install a Graphics card and enable CMS to legacy before you can boot to windows to be able to perform the mbr2gpt. His instructions here were perfect!!!
In this condition is easily & successfully convert because mbr disk has only one partition
If your mbr disk has more than 3 partitions you will meet big problem , then mbr2gpt.exe don’t permit to convert, it will show message failed !!!!
Thank you. Very useful and to the point. Shame I wasted so much time on others that were either hidden product promotions or just plain incorrect.
DUDE THANKSSSSS!!! I was ready to embark on a huuuuuuuuuuuge journey to change the system drive. Would not thought that it was possible to change the fileformat without deleting windows! THANKS MAN!
HUGE HELP. I didn’t wanna have to backup everything and reinstall windows. This saved so much time thank you !
You just turned me into a computer wizz kid.. my family think I'm a genius but we both know it was your tuition that made me this way.. kind regards and thank you for the easy to follow video.. yes I'm 53 and I refer to all film and movie clips as video😂
Thank you! This came in handy when trying to clone an old 1TB MBR HDD onto a 4TB SSD.
I found out the hard way that trying to clone a MBR drive without first converting to GPT results in an unbootable clone drive.
Awesome!!! This is what i have been looking for. I almost plan to paid for miniTool to convert my OS to GPT. With your guide, now my gaming PC is ready for windows 11. You are the best. 🥳
Life saver this fixed my issue with meeting the requirements for windows 11 upgrade since secure boot wouldn't work as I had legacy boot configuration
I can't thank you enough, after searching a lot, It really worked. I just liked your video and subscribed. Thanks a lot mate!
when i typed mbr2gpt /validate /disk:4 /allowFullOS it gave me an error disk sector size is: 512 bytes?
I had to go to computer management and shrink the C drive by 51200 then ran the validate process again and it worked.
Outstanding video. Super-easy to follow your directions and greatly appreciated the help. Worked perfectly! Thank you.
Wow, you totally de-mystified this process - thank-you!
THANKYOU!!!!!!! im late but this worked!! After months of searching and trying things
This is legit. Thanks for the easy, to the point, video.
Disk layout validation failed for disk 0
did you find the fix?
Thank you. Worked great for me! Just make sure you are familiar with the BIOS settings. Took me couple of tries to boot windows
Thanks for this knowledge man i love to appreciate your efforts ❤❤❤❤
Nice one sir I wanted to keep my pc beyond 2025 so this only helped me thank you so much.
Thanks! I followed it to the "T" and it was very useful. I ended up having to shrink my SSD down to about 200MB in the disk partition due to the validation step not working and it worked flawlessly afterward...
I already had the changes in the BIOS so when i restart my pc it worked just fine. Thanks
Thank you for the clear instructions - saved me a boat load of time!
Thanks for the information. I have two older PCs that the BIOS did not have the option. One booted fine the other failed to boot. I was able to recover the failed PC with full disk image restore.
You can also go into disk management before you restart the machine to make sure it says GPT disk
I've been at this all night and it still says cannot find room for the EFI system partition. Its a brand new 18tb drive and I copied my 256 boot drive to it. MS and windows just suck. I give up.
But when i'm trying to validate there is an error saying :-
Disk layout validation failed for disk 0
Plzz help me out this😢😢
Same here..
- "Disk layout validation failed for disk 0." -> C:\Windows\setuperr.log -> "Too many MBR partitions found, no room to create EFI system partition."
- MBR2GPT tool does not support more than three (3) partitions in the MBR partition table, and you should not have any extended/logical partition. All three partitions must be primary partitions.
Yooo, thx for the tutorial! Helped alot and got straight to the point.👉
This really helped a lot! Thanks!
Yes. Finall get all tick to meet Windows 11 requirments. This is life saver for me. Thanks 👍👍👍i have just subscribed your channel.
What to do about converting the other physical drives was never mentioned. Since it wasn't addressed, the presumption is that nothing needs to be done. Besides the OS disk, I have 2 other physical drives controlled by Windows Storage Spaces.
short , sweet and simple . thank you. very helpful video..👌
Dude! Thanks so much for posting this. You are a light unto the world.
Huge thumbs up man!
Thank you for clarifying and telling how to do the steps.
Now if only I understood what actually changed here xD
I feel like unless you are an absolute tech savy, you are just doing what needs to be done, but overall I'm being clueless what this gpt partition style differs from mbr xd
Short answer is Old vs New filesystem. You can have 2tb partitions on Mbr but 9,8ZB (9.8 billion TB) on gpt. 4patitions mbr 128partitions gpt. Mbr bIos vs Gpt UEFI.
thank you,i needed this to enable Amd SAM
Thank you for this video! liked and subbed.
Can you do this to your external drive. My computer is only reading it as a fat 32 and 29 gb when its a 4 tb drive. Thank you
Perfect video !! Very helpful

Same Here. About 18% free on my drive. Is this an issue that the drive simply is too full? Or will I have to resize partitions?
Same i used aomei partition assistant (free) and converted it
Can I have one drive gpt and the others mbr without messing up data or losing data on any other drives or the gpt one because I'm planning to clone a 2tb to 3tb
Perfect guide, thank you!! 👏
bro thanks this worked great for me without software and if you can make a video on how to change the manufacturer boot up logo as well please
excellent! worked like a charm! thanks!
Hi there. I bought a refurbished Dell desktop from Best Buy and can't upgrade to Win 11. I'm set to Legacy in the BIOS, and before changing that I tried converting from MBR to GPT using this method and it says Cannot find OS partition for Disk 0
Hello, I have two drives, one HDD the laptop came with and an ssd to which I installed windows 5 years ago and is working perfectly. mbr2gpt does not work as it says disk layout validation failed. There is a partition in my hdd of aboyut 550MB which is used by system, maybe it is the culprit and it has boot partition? How can I make it run? Thank you
you've helped me so much. Thank you 🙏🏼dropping a sub 😊
Excellent. I had looked at some articles on this, but they manage to leave out the important switch "/disk:#" This has saved me a lot of aggravation. Thanks.
>mbr2gpt /validate /disk:0 /allowFullOS
EnablePrivilege: AdjustTokenPrivileges failed (Error:0x514)
ERROR: Failed to enable backup/restore privileges.
Check that you are running in a process with elevated privileges.
Worked great, thank you!
Does it only need to be the drive with the os or all drives?
If you did it did you have to format the other drives?
OMG OMG OMG You are a life saver. Works perfectly to me!!! ty ty ty
I have 6 drives total with 4 of them being set to MBR including the OS drive. Would the process for this be the same for the remaining 3 drives? And do I convert the 3 non-OS drives before the one containing the OS?
Thank you my guy 🙌
😃😍🤩 Thank you very much I appreciate a good Command line tech teacher , I too wasted time watching how to hatchet my OS when all I had to do was buy the module for my gigabyte MoBo and then take a lesson from the Master 🍾😁
the code didnt work it said conversion failed, what do i do!?
There's no button or link to actually DOWNLOAD that file.
this helped a lot thanks man.
thank you sir! its really work! i can use now the windows 11
in the cmd after i try to convert the disk to gpt it doesnt work and it says "MBR2GPT: Conversation failed" how do i fix this
is it only necesary to this on my boot drive if I want to upgrade to win 11? or do i need to do this for all my drives?
mbr2gpt bad_module_info why?
Un énorme merci, tu m’as vrmt aide pour ça . Je n’y comprenait rien
I have covered my SSD to gpt, and it looks good, but can't boot from it. In Uefi boot priority, the drive has the name: (PO: OCZ-VERTEX2) the drive I can boot from does not have the letters PO: how do I change this? Thanks for the good explanation.
this video shoult be attached to every windows upgrade!!!!!
PERFECT! love you
You deserve a fable written about you!
Didn’t work for me.. gives me errors in the CMD prompt.
“Invalid arguments”
nice vid..thanks a lot.
Many thanks 👍👍

MBR2GPT: Attempting to validate disk 0
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
Disk layout validation failed for disk 0
i did this to disable csm
what if i want to also convert Disk1 and Disk 2? Do i need to put the MBR2GPT file in those disks? cause it worked for Disk0 but not for Disk 1 and 2. please help
Wonderful. Now i cant leave UEFI settings. People should not make tutorials without considering most/ all format people use.
Thx for your work.. my settings are already done after 3 ours of trying fix this issue
I changed my bios then it wouldn’t boot to windows and showed black
So this does not work for other drives, ie my externals ?
Merci. Cela a fonctionné parfaitement. :)
thx gonna have to do this to update to Windows 11
gives Cannot find OS partition(s) for disk 1 error

Why did this happen to me?
Happened the same to me
Mine said disk layout validation failed for disk 1
Worked nice guide
Cannot find OS partitions for disk 0 ,now what ?
This was awesome!
Dont do this in the OS like he showed! This is very unsafe!
It's very safe as long as you put "/allowfullos" at the end of the command.
On the Nintendo switch how do you make the clock like that
Thank you ❤❤❤❤
Mine had had an error and gets Validation failed
why does this not work for a data drive?
Can anyone find solution in case mbr disk system has contain more than 3 partitions to success convert to GPT disk !?!
Please !!!!
Does not work
Thank you so much :)))))
