First off, Linux likes to be on the first partition of the harddrive, as well as windows, so 9 times out of 10 you are going to have a nasty conflict with that. My base recommendation, would be getting two harddrives and setting one as your win2k OS then set the other drive as a secondary Master and drop Linux on it. Afterwards you can write a batch program in a menu format to tell the computer which drive you want to boot off of. Doing this, would probably cause you the least amount of problems. Dualbooting can lead to quite a few problems if you are just starting out.
