When i try to run 

 

mbr2gpt /validate /disk:0 /allowFullOS

 

i get the following output

 

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 read a bit about it, and it seems to not work because disk 0 isnt a system disk, but in my case it is.

I am using build 1709

I got the same error when attempting to use the mbr2gpt tool on my disk0; any ideas what could have caused it?

@Aaron B Boot with   USB windows  10 PE, and then try to enter below command

 

mbr2gpt.exe /validate /disk:0

mbr2gpt.exe /convert /disk:0

 

Note once conversion formats all partitions in the Disk 0 , you wont be able  recover anydatas .

@RAJUMATHEMATICSMSC This is not what i wanted, i wanted to convert the disk while keeping all of my stuff. (See the /allowFullOS switch
