I am using a loner computer with only 3.2 gigs on its harddrive. I bought an external one an dhave installed games on it but it still takes up room on my internal drive with now only 19 megs free. Is there anyway to run windows off of this external HD and not use the samll internal one?
Not really, Windows wasn't designed to run off a USB/Firewire connection. What you can do is open up your external enclosure and remove that hard drive for primary use. After all, it is an IDE hard drive with a IDE>USB/Firewire adaptor.
