I just got myself a 24" 3.06Ghz iMac with Nvidia 8800GS and i am having problems getting either XP SP2 or Vista to install via boot camp. After creating the boot camp partition my mac reboots, i get a grey screen for about 10 seconds, then the screen goes black. In fact it looks like the screen turns off it's so black, and there is no flashing cursor, but i can hear the disk turning so it's still on. Anyone else had this problem. I have done some searching and it looks a bit like the problem that effected some 2006 model 24" imacs but that was fixed with an MXM update. I tried to install this update but the installer says it's not needed for my model and won't install. I am a bit worried because i got this model so i could play PC games via boot camp but so far not had much luck!
