I've been using bootcamped version of vista now for nearly 6 months, no problems with it at all. I generally use OSX, but i've been downloading a game with direct2drive that was quite large, so i've kept it on windows for most of the past week. Anyway I decided tonight to go back to OSX, to find that after the grey screen, I just get stuck on the apple symbol with the moving disc. It seems to just keep rotating and nothing happens. I've put in the OSX disc, and tried to repair using disk utility, but the repair option isn't available. The weird thing is, nothing is wrong with booting into bootcamp, and I can access all of my data through vista using macdrive still, so I really don't know what has happened. Any ideas please?
