OK, Last weekend my girlfriend got a new iMac (20", 2.4GHz) and everything has been running great. Today I went to install Bootcamp for her and everything was going well but there was an error with Windows and it would not properly install. Anyway I went back into OSX, removed Bootcamp and re-installed. I repeated this twice. On the third installation attempt I tried to boot back into OSX but the computer hangs on the grey screen. I can eject a CD by holding the mouse down but I am unable to boot off a CD (holding down the 'C' key). If anyone has any further suggestions I would be very grateful as I am in the brown and smelly now!
