I'm trying isolate the physical disks/drives away from the VHDX booted OS. Physicals partitions can either be unmounted(drive letter removed) or the other physical disks themselves disabled.
The final remaining question is whether I can remove the letter from the drive containing the VHDX the system is booting from. The disk management shows the vhdx has been mounted giving access to the virtual partitions. Does that mean the system will break if I remove the drive letter from the physical drive?
