I'm building building a new pc and I don't wanna buy an optical drive for it. I also want to download windows 8 pro using my college discount so it's a downloadable version. I never did this. All I know is I need a flashdrive which I have. Can someone tell me the procedures to do this. Remember, I'm getting the OS via downloading it and installing into a flashdrive so I can boot with it on my new pc.
