I have the same problem as the person here: http://forums.macrumors.com/showthread.php?t=471825
When I boot windows xp in bootcamp everything works fine. But when I try to run the bootcamp xp in fusion it gives a bsod with error 0x0000007b after the windows loading screen.
I installed windows xp in fusion from the same cd and that worked fine, but I also want to run my bootcamp version in fusion.
