Let's cut to the chase. You're not fussy about losing Mepis (if I remember). Re-install Mepis as if from scratch, telling it to use the already created Mepis partition. You'll probably need to go into Advanced mode, when the gparted screen displays during installation.
That way the scanning for grub entries will be re-done.
Just for reference:
cat /boot/grub/menu.lst (might need to prefix with
sudo)
Mine is about 4 pages long with entries!

Windoze will show as:
title Microsoft Windows 2000 - or similar
rootnoverify (hd0,0)

But really, I think you should go for a Repair install of Win2k.
Boot the win2k CD:
# At the first screen asking you if you want to perform a repair or new install, select Install Windows 2000 -> Upgrade to Windows 2000. Don't select repair or recovery on the first screen.
# Setup will find the existing Win2K installation (usually C:\winnt) and ask if you wish to install over it or repair it. At this second prompt, select Repair. Note: If the Setup program does not detect a previous installation but just continues to the partitioning screen, there is a problem. Stop!
Also, see the Manual Repair option here:
