I'm not alone, there's a thread on the Apple boards where other people with the same setup have the same problem. It's also apparently happening with the 24" iMacs. The problem: using Boot Camp Assistant 1.1 Beta, restarting to install Windows XP SP2, the machine boots off the CD and then the screen goes black. That's it. Screen never becomes active and it's impossible to continue from there. I know the install disc is good. I also tried unplugging all unesessary perhipherals. No change. People don't appear to be having any more luck trying other displays either.
