Resolution

If you have a Time Machine backup copy on an external hard drive, try to restore the virtual machine from the backup. If you do not have a backup, the virtual machine is lost, but you can still retrieve the data from your virtual hard drive:

Option a:

  1. Locate the .pvm bundle of the Virtual Machine > right click and choose "Show package content";
  2. Choose .hdd file > right click > open with Parallels Mounter. Virtual hard drive will be mounted on Finder;
  3. Locate the files you need and copy them to the Mac side.

Option b:

Create a new virtual machine, install Windows there.

In configuration of the new virtual machine go to the configuration editor add the hard drive image of the corrupted virtual machine.

After the start of the new virtual machine, additional hard drive image will appear as an additional labeled disk.

Copy all the necessary data to disk C , untie the hard drive image in configuration of the new virtual machine and delete the .pvm bundle of the corrupted virtual machine.
