I just built a pc, or you could say I replaced almost everything on it. What I didn't know was that old HDD won't run on your new setup, I googled around and the answers were to reinstall the HDD, BUT! I had to replace ALL the parts just to reinstall. Isn't there a easier way? Couldn't it be possible to plug in a usb mini with windows 7 saved on it and re-install? And if so, how do it?
