    Whenever i try to run mbr2gpt it says disk layout validation failed


    Hi,

    I'm trying to get my drive from mbr to gpt so I can boot with UEFI, I didn't want to lose my data so I decided to use mbr2gpt, When i did and used the command "mbr2gpt /validate /disk:1 /allowFullOS" it gave me the error saying "Disk layout validation failed for disk 1", I have tried multiple things but I do not know what the problem is, if anyone can help thank you.

    Windows Version: 10.0.19043

    I included my Disk Management Window.

    Well, start with the fact that your Windows installation is split between two disks. @NavyLCDR for example is an expert on partitions.

    Further methods are given here:
    Convert MBR Disk to GPT Disk in Windows 10
    - compare the partition layouts-

    but you'll need to resolve that problem first.

    After you boot, look at disk management again. In the bottom half where it says Healthy (.....

    The partition that has the word "System" in the parenthesis is the partition the computer booted from.
