    Newish 20" iMac (black border around glass).

    Wiped clean and installed Snow Leopard, ran boot camp wizard and gave the windoze partition 100 GB, then rebooted.

    No matter what disc I try to boot from (Windows 7 burned, Windows 7 pressed from microsoft, Windows XP SP3) I just get a black screen with white lettering in the top left that reads:

    113-B22505-011 M74 GDDR3_16Mx32 64bit

    Haven't been able to find anything on google. I figured the win7 might be problematic due to the way microsoft makes their discs (have had to burn mac-friendly dvd versions in the past) but I can't figure out why the XP cd wouldn't work...

    Any ideas would be much appreciated,
