Uninstalling windows 2000 and delete partitions

[fritoebola]

Hi, I'm trying to unistall win 2k. the problem is that everytime i tried to, i install a new os like a diferent partition, have no idea of how that happened (what so ever) so now when I start my laptop i have to decide between win 2k and win 2k to used it; :-/ and the funniest thing is that they are not the same, one was intalled a month ago and the other a week ago, I also have an unfinished intallation for the last time I tried to fix the problem so now I have to choose among win 2k, win 2k and win 2k setup before starting to use my laptop.
I just want to format everything and intall once and for last win 2k.
I have no idea (again) how to clean the disk, i'll REALLY appreciate any help.

Thanks a lot.

Boot to the w2k disk, delete all the partitions, make a single partition, format to ntfs & you're good to go.
Read the above link.
Read the w2k screens.
