Simple question. I sold my original boot drive, upgraded my rig, kept my old hdd but it never had windows installed, just my games and files. How can I install windows onto it & keep all my folders intact? I can borrow another PC if necessary but i'd like to not have to. Also please go into detail about partitioning and formatting since when I made my original boot drive it lost a ton of gigs from poor partitioning on my part. Thanks!
