This is actually happening to my son's laptop. He is running Parallels3. When he started at first he had this black screen which scrolled numerous "orphan file being repaired" notices, then "orphan files being moved" then a blank blue screen. Now when he opens parallels it says VM is suspended. If he says to start he gets the XP Flag on black screen then he gets a sequence of black w XP Flag, then blue, then white and it keeps repeating this cycle. In one of the screens there is a microsecond display which we best make out to say "image possibly corrupt, checksum does not match the computed checksum" It appears that we have a "windows problem" I'd like to try to repair windows but cant figure out how to shut down this VM so I can get it to boot up off the CD and WiIndows install disk to repair windows. Any suggestion would be appreciated.
