I downloaded Windows 7 Pro 64-bit through the MSDNAA site and burned it to a disk. It seems to freeze although I'm not sure cause I only waited for a few mins since I had to leave. It freezes right after the "Starting Windows" screen, there's an arrow which is very not frozen and a perdy blue screen but it just sits there and the DVD drive stops spinning BTW. So should I just keep waiting or should I re-burn at a slower speed? Thanks for any help!
