ok I have reinstalled and formatted windows 2k many, many times.
1st. Create the 4 system disks from control panel. label them. This is your startup/format/begin install of windows 2k. Cant use Dos format disks for win 2k and above.
2nd. restart computer and load from a: hopefully you did save everything you want.
3rd. It will ask you for the cd after the 4th disk is done loading. Follow the directions from there.
4th. as soon as you are done loading... install the new service packs, very first thing!!
BTW in my opinion the only other stable OS by Microsoft would be XP professional but win 2k is on all my systems
