MBR2GPT Disk layout validation failed for disk 0 

Does a recovery partition count? I have followed your video transferring my system reserved file into the same disk as my OS but now I have four partitions: My OS Drive, another usable partition, my system reserved, and recovery drive. Is this the reason why my conversion won't work?

Do you have registration code for Stellar Phoenix Data Recovery or Recoveryit? Just need to retrieve important files on the disk F that become the DVD after rebooting and might did something with the partition due to the malware that I had to remove. Now, Ican retrieve the old files but not the files for this year and last year files

I have a question, can I move the OS to SSD but leave the data on HDD.

EnablePrivilege: AdjustTokenPrivileges failed (Error:0x514) ERROR: Failed to enable backup/restore privileges. Check that you are running in a process with elevated privileges

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.

this is too complex for me is there any other easy tools😳

i cant shrink it in 102400, can anyone help me?

The UEFI standard has been around from somewhere in the 2005/2010 period, so "if your machine is 8 to 10 years old" in 2019, there is a good chance it has UEFI.

I've only 2 partitions on my Disk 1 (which is where my Windows are installed) but still got that same exact error, what should I do now?

Hi I am having issues after following all the step. Seems like window is not starting and asking for a drive to boot. After I reset to legacy something popped up like Grub. Please help me

Excellent video, but it did not work for me. On Disk 1, I have the OS in the C: partition. As your video shows, I created a new volume/partition. I had two; you had three; I do not have a System Reserve volume on Disk 1. When I try 'mbr2gpt /validate /disk:1 /allowfullos' I still get the error "Disk layout validation failed for disk 0." Both my partitions are Type 7. (I tried a variety of partitioning, none worked).

Great videos but still stuck on my issue, can you help? Tried to attach a link to image on google drive of diskmgr partitions but comment deleted (due to that link I suspect). Full error on my win10 drive is as below. I am booting from usb (win10 rufus created WINPE) as my new motherboard/CPU won't allow legacy bios to boot from my hard drive (hence the attempts to convert it!). I tried to shrink partition 2, but could not extend into it from partition 3 with diskmgr, and when i tried to extend from partition 1 it warned me about creating dynamic partition, so I cancelled. This meant I had 4 partitions if formatted, assigned etc, which fails on mbr2gpt due to > 3 partitions. Considered removing reserved (part 1) or recovery partition (3), but nervous about trashing drive permanently without being sure of correct option to progress with. Can you advise? follows: MBR2GPT was explicitly asked to run in full OS mode.

this didnt help but im thankful for the attempt !!!

Did not know about 3 logical partition limit. Thank you, I will try that.

I have an SSD (Disk 0) which I boot my OS from, but I have a Recovery Partition at the end of my Disk 0 which I can't remove or move and I think is stopping MBR2GPT validating. Any thoughts?

OMG IT WORKED THANK YOU THANK YOU THANK YOU

Thank you for this extremely useful tutorial. Precise, to the point and well illustrated. It helped me out when many others failed.

well done I am by name Umar yusuf , and my problem is I try to convert but it failed with the note "find room for EFI system partition`` thank you.

i did it the hard way, too. There is a program offered for no cost @ Paragon.. Admin Command Prompt- mbr2gpt /convert /allowfullos did it for this OptiPlex 9010 PC (after a few checks like disc validation). So far so good, anyway.

Came here after a long struggle to convert from legacy to uefi and finally found the correct video. Thanks man it helped me to change to uefi. This video will be helpful to a lot of people now that Windows 11 is a thing.

READ THIS IF YOU ARE HAVING PROBLEMS Thanks didn't solve my problem but you showed me exactly where to look for the error to debug. It showed me that my system reserve wasn't on the same drive as my OS which must have happened when I first built my PC apparently when you download your OS you need to make sure you don't have any other drives plugged in because I did and some reason the system reserve was sent to the other drive. So that being said I was able to create a drive letter for the system reserve < original one. Then on my OS I shrinked the volume and created a partition and transferred the system reserve to the new partition it can be complicated but if you are knowledgeable you can handle it there is certain commands in the cmd prompt which "robocopy f:\ e:\ e:/" you will only be able to transfer 3 files the rest well idk I just said screw it. After that I got rid of the letter format and set the partition as active restarted my PC and it allowed me to convert MBR to GPT

It doesn't work for me, my local disk is disk 4, also if I try it with programs it tells me: invalid configure file or the system partition and boot are on different disks, I don't understand anything.

THIS syntax is correct for Dell Optiplex PC. as well as other Dell PCs withe a recovery partion .>>> mbr2gpt /convert /disk:0 /map:222=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 /allowFullOS

My problem is that my disk 0 looks just like yours at the beginning of your video; I go to the shift/restart and computer restarts i get to command prompt x:\ type in mbr2gpt.exe /convert AND STILL I get the validation error. And I do have 21H2.

hi! can u help me pls on discord maybe? i have 2 partitions and still cant convert. i tried easeUS partition master..it kinda worked..it says GPT in diskmgmt but in system info it says BIOS: legacy. and also i cant disable CSM (cant boot). i wanna turn on resize bar for gpu

Hello sir, i have tried to clean install my system so with creation media tool i made usb bootable and then in setup, i deleted c drive 😅 Now, while trying to installing windows in unallocated space or memory, it says windows will install only in gpt disk.. till now it is fine and i found that my pc disk is in mbr partition mode and by default system boots through usb in uefi mode. Now while trying to convert mbr2gpt validation fails like you showed in video and i found solution that i have to delete all partition made by user but problem is that it has important data and remember c drive is deleted so what to do now so that i can not loss data

Hi sir. How i find out that my laptop dell d630. (Windows 10.it's now legacy mode ) to support to convert, and change legacy mode to uefi ? Because i tried twice and failed. First time i am totally got stuck my Windows won't start only blinking cursor on the left top corner on this screen. So install os .second time also happened same.

Can the recovery partition cause, that I receive the same "Disk layout validation failed for disk 0" message? Deleting recovery can help to perform this conversation?

Hi I actually saw the logs in my c drive and instead of the one you got I got disk layout validation failed for disk 0 failed to retrieve geometry for disk 1 [gle=0x0000002]

4:36 , so i will not to be able to change my disk? , i have 2 disk , disk 0 is hdd 1 tb and disk 1 is ssd m.2 240 gb THAT has windows , what can i do i have the "4:36" error and i have no partitions on any disk

What to do if the error message persists? "Disk layout validation failed for disk 2" (in my case) Someone please help me...

Should I delete the new part of 100 gb ssd after convert ?

Thanks bro for help 😭

hi, if i have the windows on disk 1, how can i make disk1 as active, it fails with that command. i dont' want to lose data from disk 0, so just convert disk 1 where windows is.

I mean I’m scared to do this I’m scared it breaks my pc I have disk validation failed actually

Type out the line of selecting let's say partition one cause I have 2 separate disks

I have 2. boot patrioten. do you can help me or someone who know I can fix the problem?

Yo what if it says ValidateLayout: Too many MBR partitions found, no room to create EFI system partition. Error Disk layout validation failed for disk 0?

Mbr2gpt convert success but window 10 not start in uefi mode

how would i fix "Cannot find OS partition(s) for disk 0?"

Thank you. Your video have been very helpfull!!

Should I make Disk where system installed active?

This is an informative tutorial, and I also fixed by converting from mbr to gpt with ao mei partition this one is nice.

How to know whether my laptop supports uefi Or not

Cannot find room for the EFI system partition.? What can happen?

do I have to need some unallocated space to change my disk partition style MBR to GPT? actually I have to change my disk partition style but could not do. I have a 476939 MB hard disk along with 1MB unallocated space. I used your command line to convert but getting the same error that is disk layout validation failed for disk 0. my motherboard support UEFI so I want to switch Legacy to UEFI therefore I need to change partition style but would not do that because of losing data. But your video shows that one win10 user can easily switch MBR to GPT using MBR2GPT.exe therefore I need your help.

Hi, Thanks a ton for this video. This helped me to resolve the UEFI issue I was facing, while converting from Legacy to UEFI. Watched couple other of your videos as well in order to resolve it. Thanks again.

Hello I have a situation here I am still getting an error. I don't know of what the main reason is but I can tell what I have. On my disk 0: I have system reserved and hard drive and for disk 1: c drive , new volume and something like 508 mb healty(recovery). I would be greatfull if you can help me figure out. Thank you

I got geometry fail to retrieve for disk 1 how do I fix this

How we check my machine is support uefi mode or not

Hi, I am getting this error. PLease advise C:\WINDOWS\system32>MBR2GPT.EXE /validate / disk:0 /allowfullos Invalid argument: / Invalid arguments Converts a disk from MBR to GPT partitioning without modifying or deleting data on the disk.

Hi. I'm only having four primary partitions c:, e:, recovery partition and system reserved partition. Yet the mbr2gpt validation fails. I'm having a lenovo ideapad 330 machine. what are the possible reasons?

I have 3 different disk drives with 3 different partitions (C, D and E). One partition for each physical disk drive. My disk drive that has windows in it only has one partition. Is that ok or do i need to reduce my total no. of partitions?

Hey, I have the same problem, but for different reasson. I want to turn on resizable bar, but i have mbr disk so i have to change it to gpt. But i have efi partition on other disk than my system disk (bootable) so i cant change mbr to gpt and i cant move my efi partition to the system disk because it is a mbr format. Could you help me Please? :((

Bullshit. U got no idea about possible problems

Why you tried first Disk 1 and failed and later you did with Disk 0 9C: drive), Why it doesn't work with Disk 1 (D: drive) ? Thanks !

I converted my disk form MBR to GPT with partition assistant it also works well

My extra partions on Disk 0 cannot be deleted. in fact, I can't delete any partition on any drive. Can you tell me how you were able to?

First partition too close to the beginning of the disk. Should start at offset 17408 or above, found at 4096 #my error

Thank's. I configure my acer aspire laptop. I hit the subscribe button and like as well.

I'm having the same issue but this example still hasn't fixed the problem. you have any ideas on whats going on

Please help me sir,me unable to convert it, help me out through Anydesk id please sir

I'm getting the error: "ValidateLayout: First partition too close to the beginning of the disk. Should start at offset 17408 or above, found at 4096"

Cannot find room for efi system partition.

it says Failed to retrieve geometry for disk 1

you saved my day!!!!! thank you so so much

I get error: cannot find room for partition

I am so happy! you explained it really well! THANK YOU! I was struggling with this error all day!

After complete conversion is that any data lose occur in another partition like personal files.?

Hey pls please help me out if you are seeing this comment... I tried it....i made 2 partitions in disk 0...one C.....one is system reserved.. But it still says validation layout failed...I went to MS website for help...tried shrinking partitions too which I saw there in the website...but still didn't work...pls help me..I have all support....From UEFI to TPM 2....but this single conversion...mbr to gpt....it's stopping everything...

Wow, you really explained it way way better than some of Microsoft employees did. I am gonna convert it, hopefully, it won't wipe out the two partitions.

It gives error EnablePrivilege : AdjustTokenPrivileges Failed (Error:0×514) Error: failed to enable backup / restore privileges . Check that you are running in a process with elevated privileges

Why does it say for me "cannot find os partition(s) for disk1/disk0???

Bro I did the same thing but when i do the convert and validate the coding is stuck

hello bro need your help...I've 3 partition as like you but when validating it says "Cannot find OS partition(s) for disk 0"!!!! but my os is running from disk 0. what should I do?

I created a new partition as you did but to me always same error. can you help me out?

This means I can't Convert to GPT without loosing data? Is there any way? As I'm am trying to upgrade to Win 11 and it needs UEFI...

IT WORKS! thanks a ton mate!

thanks u bro. u really help me! I think i go crazy with mbr->gtp

Full confusing video

thanks bro but i hv an error Cannot find OS partition(s) for disk 0

I got lost. I have to partitions in my SSD. and gthere is another 558 mb for recovery. Dude I got lost when you made the partitions. Help

It finally work's now thanks now I can switch to Windows 11

Its not working for me

Great Video! This mbr2gpt.exe is not very helpful with pointers about what was wrong and why it didn't validate in my case. After watching your video had a look in those error logs, which was really helpful. In my case it returned Volume: , Error:0x00000012 - which was in fact exactly what you showed at the end. Basically it can't proceed with Extended Partition (Green in Disk Management).. Anyway.. issue is - If someone will be dealing with similar scenario: In my case I had data on this partition, which was crucially important to save without deleting/recreating - some proprietary software with database etc. So.. solution is to use third party software such as AOMEI Partition Assistant, which has a feature called "Convert" Extended to Primary. After doing so - mbr2gpt.exe does its magic with no troubles ; ) And.. Voila! Up to date build with UEFI boot / Secure Boot enabled etc + saved stuff on safe OS. Thank you!

Please help me... I have 2 hard drives.. it converted the wrong drive(disk:1) which I am not concerned with. Disk 0 is giving me an error that says cannot find OS partition for disk 0: conversion failed. My disk 0 has 2 partition. The primary partition says boot, page file, active, crash dump, PRIMARY partition. The 2nd partition on disk 0 says healthy recovery partition. I noticed that in the main partition for disk 0 it DOES NOT SAY SYSTEM. How can I get a successful gpt conversion to work on disk 0?

Why does the validation fail when there are more than 3 primary partitions ?

my error shows too many mbr partition found no room for efi creation

Almost a great video. Not quite great because it didn't work for me, sadly. I got as far as "mbr2gpt /convert /allowFullOS" and waited, and then: Conversion failed. Cannot creat EFT system partition. Error 0x000036B7. I'm still on MBR. So now I'm back to square one. On disk 0 I had 500 mb NTFS and the C: partition was 465 gb on which I then created a new partition of 500 mb. [Unallocated] so I have now 3 partitions. The validation part worked, "Validation completed successfully" but not the conversion. I just found this in Windows but I don't understand it. Error ValidateLayout: Last partition too close to the end of the disk. Should end at offset 500107845120 or below, found at 500107862016 So I shrunk the 465 gb partition so the new unallocated partition is now 15 gb, but that still didn't help. Can you or anybody please help? I've been at this all day and it's now 10 pm. and I'll check tomorrow if anyone has read my problem. Thanks.

I'm getting this error "ValidateLayout: First partition too close to the beginning of the disk"

If I convert from MBR to GPT does it loss all of it's data?

I didn't really understand what to do sir, I have 4 partitions do I need to merge two of them to make them 3 partitions for it to work?

This helped me somewhat. The error was "Disk layout validation failed for disk 0". Had to shrink by only 1MB then it finally agreed to do the convertion

u're a king

Does this method led to data loss present in my other drives

i am facing a dilemma ,,my disk count is 4 the forth one is hp tools ,is it safe to delete it ,,and if i recreate it after will it work as it should
