Assigning a letter to OEM Partition

Question

I'm trying to do an exact clone of my laptop. There is an OEM partition that I can't assign a letter to. I'm using DISM, which uses the drive letters to know what to capture.

I was wondering if there was a way to assign a letter to the OEM partition. I've looked at diskpart and assign letter does not work for OEM partitions. I was wondering if there was a work around.

Also I looked into partitions and volumes and it was a bit confusing, how are they correlated? Are partitions subsets of volumes?

EDIT: I'm pretty sure partitions are subsets of volumes, but I can't find verification anywhere.

Answer 1

Partitions are storage units used to divide physical disks into smaller, independent parts. Basically they're containers for filesystems. Volumes are storage units with a filesystem. A volume can be inside a partition, but it's also possible for a volume to span multiple partitions.

As for assigning a drive letter to that particular partition: you need to determine the type of the filesystem inside that partition first. GParted might prove helpful there. Windows can only mount FAT(32) and NTFS volumes. For other filesystems (like Ext2/3/4 or XFS) you're going to need 3^rd party tools.
