MBR2GPT Disk layout validation failed
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 ...
Here is an easy fix it has worked for me every time. In the below example vol 2 was my boot drive:
DISKPART
list vol
sel vol 2
shrink desired=500
Reboot, then run the validation check again.
You should no longer have an issue and should now be able to /convert. :)
Does this format partition and delete all data from it?
