I agree with the answer at your other post at http://forums.cnet.com/5208-6142_102-0.html?threadID=354616
i have windows 2000 and since for some reason microsoft pretty much forces us to upgrade i want to. i have a windows xp os disc with service pack 1. when i try to install it it tells me that it cant upgrade from 2000. 3 questions... why is this happening? can i just delete my original operating system and replace it? and if so how would i do this. also why since you cant do much with 2000 cant you just upgrade. i cant use my webcam, kodak easyshare, or internet explorer 8.
