For quite a while I've had a reasonable well-working system that works for running Windows XP sp2 in both Boot Camp and Parallels (using the same installation of XP). Suddenly I can boot XP in Parallels, but not Boot Camp. In Boot Camp, it just goes to a black screen, no cursor, no splash screen etc. I've been unable to even get to "F8" help screen. I do see this article: http://kb.parallels.com/en/4672 however I'm not sure if this is the same issue and I'm hesistant to proceed.
