I have the latest build of Parallels 3.0 (build 5636). I use Windows Vista Basic through the Boot Camp partition. Parallels launches Windows with no problems. However, when I try to boot Windows Vista Basic through Boot Camp, the black screen with the green bar and the Microsoft Corporation copyright appears, and then before it switches to the next screen, I get a split second blue screen of death and then the computer reboots itself. I video taped the incident, but since the blue screen of death scrolls the message onto the screen, the computer rebooted before it could tell me what specific file may be corrupted. I've already tried the following: 1. Booted the computer with the Windows installation DVD to do a "start up" repair attempt. 2. Created a new virtual machine. 3. Done a system restore to before the new version of Parallels was installed. There was a time when Parallels froze and I had to "force quit" it. That could have corrupted something with the Boot Camp partition. Could that be the case?
