Hi folks. Burned a DVD with windows 7 on it, when I boot from it to install it, I get to a DOS screen, and I have this: "1. 2. Choose boot option (or something along that line) _" And it's waiting for me to type something. Anything I type, nothing shows up - it does not recognise the keyboard. No idea what to do. I went and installed old XP instead ;(, (which went fine).
