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 ...
I was facing similar problem as my disk partition was in MBR format but I need it to be GPT format.
Disk validation failed.
Easiest way is solve this problem is as given below.
Go to Disk Manager -> Select disk (0 or 1 ) you want convert and select the partition eg. C -Drive
Right click --> Shrink the disk and put shrink value to 200MB ->OK
Go to CMD with admin mode run the below command
mbr2gpt /validate /disk:0 /allowFullOS -> Enter
Validation is success
Run below command to convert
mbr2gpt /convert /disk:0 /allowFullOS
Disk will be converted to GPT
Go to BIOS and change Legacy to UEFI mode and change boot sequence
Your system will boot with mfg logo

I did not work for me. My system drive is on disk 1 and not disk 0. Maybe that is the reason why.
