i have a dell c600 laptop and have xp installed. however most of my hardware i bought and the modem on this laptop isn't compatible with XP and there are no drivers that i can find. would it be possible to install win2000 on the same laptop and select which OS to boot at startup? my friend said he suggests (without formatting) to install 2000 on a different partition. not sure how to do that. i would like to try to do this without having to reformat first.
