Yeah, you would put XP Lite on a disc and boot it up. If you wanted to install it over everything, though, you would have to set the CD-ROM as the first thing to boot in your BIOS.
ok thanks oh i forgot do i have to press anything to boot it up and can i uninstall it if i wanted to and one more thing i promise, there is no keys and serials to put in is there?
well i did it, got it and put it on, its really good, i put it on a windows98 pc with 3.21GB mem and 96MB ram, and it seems to work alot faster now! than it did with windows 98
