MBR 2 GPT

[whistleblower52]

Hey all, I'm trying to convert my ssds to a GPT format so I can enable SAM. When trying to run the command I get disk layout validation failed and i'm not sure why. I have done as much troubleshooting that I could find but need some extra help. Things I have already tried: Made sure there is enough free space on each partition, only have 2 partitions on the drive, and bitlocker is disabled. Any help would be much appreciated thanks!

Do these disks have anything important on them?  Are you trying to do it to a disk you booted of of?

I've done this a few times on some older machines. Are you booted to the installer and running the command from the command prompt there? You can't be IN windows on the drive you're trying to convert.
