Im trying to install Windows 7 RC on a new partition (Vista is installed on another), but I get no option to boot from disc when I restart. So I set it to boot from disc in the bios, and it boots up through the black screen with "Windows loading files...", then shows the 'Starting Windows" screen with the windows logo, then it ends up at a green-ish screen with flowers/graphics etc. This screen (which im assuming is the setup screen) is just completely blank in terms of text. No options, no loading, nothing. This happens every time I try and boot from the dvd. Any help/suggestions?
