I just finished my first gaming build and have run into a bit of a problem. I can't find my flash drive that I keep win 7 on. I have a 500gb external hdd that I have win 7 on butit has a bunch of other stuff on it as well. Whats the best/easiest way to not erase any of the stuff thats on it but boot up win 7 to install on my new rig? I can hardly wait to try some games out and this little set back is killing me now. lol
