is there any way i can install windows on a new hard drive while i have windows running on the main(old) hard drive? here is the deal, i bought a new 40gb hd from a friend for $15. and i want to reformat the one i have now, but i want to keep most of my files without making 50 cd's. so is there any way to install windows on the new drive while i have windows running on the old one? and then boot from the new one so i can reformat the old?
