Macbook Pro, OS x 10.6 I had several windows open, including Win7 VM. Response became snail-slow. Finally forced close most, then shut down. Now, Windows 7 VM can't be found; Parallels wants to install new Windows. I can't find any trace of Win7 on disk. MacFarland
Search in Spotlight the following line : ".pvm" it will find all pvm files on your hard drive. Usually VMs are in /User/Documents/Parallels/ or /Users/Shared/Parallels/
Having Same Issue I'm having the same issue - VM seems to have disappeared. I can see the Windows 7.pvm file (just under a Gig) in the Users/Shared area, but when I double click to activate, it starts Parallels Desktop but the startup screen says that No Boot Device is Available. I can see in the Applications folder a folder (Windows Applications for Windows 7) that seems to be a link to all of the Windows applications that I used to use on the VM, but I can't see where it really resides. And assistance gratefully received - I have my MacBook out far from my homebase, where the Windows disk is located.
YOu VM is corrupted. Windows installation need to be repaired - and as you have already noted - you will need Windows CD in order to try to fix it: http://kb.parallels.com/en/5223
