Parallels Mounter only mounts system volume

Hey guys,
I'm been banging my head about this issue for a couple of days,
But couldn't find the answer anyway.

I have some windows virtual machines, on Parallels Desktop 11.

I am trying to mount the volumes, using Parallels Mounter.
I have 2 different windows VMs,
And also have past backups of them.
One of the windows VMs is not booting to windows (some system32 file got corrupted).

Before attempting any fixes to the OS,
I want to mount the VM and copy some files.

Problem is-
Whenever I mount a VM with Parallels Mounter,
It mounts the systems volume (the one which is a few MB of size, and have the boot files for the system),
And not the actual volume with windows and all of the data.

I don't believe it is an issue with this specific VM, as the other VM is working perfectly, but when trying to mount, gives the same issue.

Same goes for past backups of the same VM (which boot, but is not up to date).


Any suggestions?
