So I've been searching sites for days looking for a solution but yet to find one. When I partition the drive with the bootcamp application it restarts and goes to a black screen. The only way to get away from this black screen is to restart and hold option. After holding control my Mac HD and Windows installer USB are the only two things there. If I click on the windows USB it goes back to the black screen. Any help is appreciated because this is currently the most infuriating thing I have ever done. For the record I am on a 2012 iMac with OS X 10.8.2 with a 1TB Fusion drive. Oh and I called Apple but they did not give me any fix and tried to pass the problem onto my Windows disc, which is a legit copy of Windows 7 I had on my previous PC.
