Windows 10: Disk validation failed. I am trying to boot to UEFI but MBR2GPT is not working.

Here is a picture of the promptI just can not find a way to figure this out.I have to disks: 1 HDD and 1 SSD where my OS is installed.Someone said that I might have to remove my HDD to get this to work, but some other guy said I don't need to remove it because I have only 2 disks, but If i had more than 3 I would need to remove 1.How can I do this without losing files or needing to re install windows.....I hate this..I need to do this before I can update to Windows 11...

MBR2GPT not working; disk layout validation failed for Disk 1

Hello,

I'm trying to convert my C: drive to GPT in order to enable resizable BAR. I used MBR2GPT but I'm getting error, saying that "disk layout validation failed for disk 1". I ran the command after rebooting to the command prompt.

I would really appreciate any help in getting this to work.

Thanks,

JJ
