I am upgrading my cpu and mobo. I am also looking to add 120gb ssd. I currently have a 1tb hard drive with windows 7 on it. When I install my new mobo and cpu I would like to put the fresh install of windows 7 on the ssd. When doing that should I keep my 1tb hard drive unplugged and when windows 7 installs on my ssd plug it back in? Or do I have to erase that hard drive then plug it back in, if so how would I erase whats on there? Then after I erase it and plug it back into my computer how do I make it so its ready to use for windows 7? Also I am a newbie to computers if someone could give me clear directions it would be much appreciated, thanks.
