I bought and downloaded windows 7 pro with a student discount. I bought it for a new computer I've just built. I can't seem to figure out how to make it into a bootable disk. it says it's an ISO but it's actually an exe DLMWin7pro64US-ISO.exe. This is the last step before i'm finished with my build. I've tried using an old upgrade disk that I got for my laptop but it would never actually install. I installed ubuntu linux on it just fine so it's not a hardware problem.
