If the OP has deleted Linux (and hence grub) there is no point in a grub solution, the M$oft MBR needs to be re-written.
As suggested above, this can be done from the Win2k install disk - no need to build a recovery disk if you have it. Simply boot the disk and hit "r" when it says so to get into recovery console. Then run fixmbr.
There are ways of also fixing this from some Linux liveCDs (maybe even SGD although I haven't looked for that feature), but the Win2k disk is probably easiest.
Edit: d'oh - we must have been typing at the same time ...
