Hey all, I've just finished building my new computer, using my old hardrive running windows vista. As an Engineering student, my University gave me a free copy of windows 7 which I had downloaded. I have burned the .iso to a disk. On insertion of the disk it automatically boots vista, If I tell it to boot from CD/DVD is pauses for a few moments and then continues with the boot up of Vista. I'm running Vista x32 at the moment so I can't install windows 7 x64 on top so I need to do a clean install. I'm using a ps/2 keyboard so the USB keyboard not reacting in BIOS isn't an issue. Anyone have an idea? Thanks.
