MBR2GPT Disk layout validation failed
I am afraid it did not. I used the following command to no avail:
mbr2gpt/disk:1 /validate /allowFullOS
and I still get that the validation of disk 1 failed.
edit: I also shrank the drive first by 200MB, and then by 2GB, and that did not work either.
It should be
mbr2gpt /validate /disk:1 /allowfullos
There should be a space before each /
Make sure you running command prompt in administrator mode.
If it were a matter of syntax, it would have shown. I still did try it out
mbr2gpt /disk:1 /validate /allowFullos
and I started Dos as administrator. I wish someone from MS would react. As grateful as I am for your concern.edit: according to AOMEI partition assistant, the boot partition and the system partition are on different disks and that I should not convert disk 1. I suppose I'll have to make the system disk as disk 0 to get any further.
I still would like to thank you for your contributions.
i dont think its system partition issue. see the screen shot of my disk 0, which is my converted disk. it has system resevered, os and efi partitions + the 2gb un-allocated space.
can you check and verify if your disk is mbr? I just did a validation and it failed as well. Im wondering if it fails once the drive is already converted to gpt.
Heres link you can follow and try the conversion from preOS environment. its basically the recovery environment.
