I'm trying to install Windows 7 Professional using my USB right now but whenever I start the installation I get an error saying CD/DVD Driver missing or something along those lines. People have said to use USB 2.0 but I'm not sure I have that. People said to install some USB drivers or something but I'm not sure how to do that either. I need help resolving this issue. If anyone needs my specs I can post that as well. Thanks.
