How do i get around the issue of it only being able to restore on the same type and size drive?
The non-resizable image type is not actually forcing you to only deploy to same type und size of disk. The destination disk can be larger and deployment still works in most cases.
Nevertheless it would be interesting to find out why it cannot find resizable partitions. So when the NEW capture is done, go to the directory /images/MB-RH-RMLS on your FOG server and open the text file
p1.partitions. Post the full content here.
