> disk image of OS HDD
This was helpful to me. Days after making that, I made a files/rsync copy of OS HDD root (recursively). The files copy was missing things which were needed for Apache server to work after switching OSes. Files copy was lacking files in /usr/lib/apache/modules/ IIRC, even though I rsynced it as sudo. (Restored those files after mounting part of the .iso.) So to properly copy operating system files: make a disk image, or, compare src and dest paths (have an index of both w/metadata).
