MBR2GPT Disk layout validation failed
I did not work for me. My system drive is on disk 1 and not disk 0. Maybe that is the reason why.
Thats the drive you have OS installed on. For me it was disk 3 and my new nvme drive was actually disk 0.
I was changing from sata ssd to nvme ssd. So i copyed the data over to the new drive and then performed the switch on the new drive keeping my original drive as a back up in case some didn't work right on the new one. So far i havent had any issue.
One thing to note is that when you do the conversion, you need to point to the system drive. I believe the end of the convert command you need to type /disk:[system drive] (in your case i guess it will be /disk:1). That will point program to correct drive.
Hope that helps.
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.
- I think there is issue with you syntax.
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.
