My 20" iMac was giving me issues, so when I received my 27", I decided to do a full restore on the 20". I then updated the machine to its newest updates, and then ran bootcamp. Everything was fine until I had to restart and install Windows. Now, I am just getting a white screen, and its not responding to any key gestures. I tried to hold down D on startup, with the iMac install CD in it, and nothing happened. Tried it with C to, and again, nothing happens. I get a folder icon with a ? in it, and thats all. Anyone have any suggestions?
