Hi. I had a fatal crash of the VM. When I tried to restart Parallels using the .HDD file, I got a drop-down message that says: "There is no operating system installed in the virtual machine." Luckily, I back up my .HDD drive each day. I went to yesterday's back up. Same message. I went to the previous backup. Same message. Each of these HDD files have Windows XP as the OS, so I don't understand why I would be getting the message. I don't have the OS disks anymore. Detailed message attached.
