I like to keep my tower out of sight behind my desk, it stays cool back there since my air conditioner is there and also is just nice not to have to see the big tower (Sunbeam Transformer). The only annoyance with this is I'd need to get up to use my disc drive, so as a work around I figured I would buy this external DVD-RW which seems very nice looking and would do what I need...not burn discs, but give me access to a drive to play games without having to get up. Anyway my question is, can a USB external drive be used to install Windows? Ordinarily you'd put in the Windows disc, make sure the BIOS has CDROM as the first boot device, and push any key then proceed to install the OS. So can a USB external drive such as this do that? Or do these drives only work once in Windows.
