Hi, JT.
NTLDR is the FIRST file that the computer loads from the HD when booting
Win2K (or any other NT-based version of Windows, such as WinXP). The
NT-style boot sector looks for NTLDR (the NT Loader) in the Root of the
first active (bootable) partition of the first HD the BIOS sees when the
boot begins.
If there has been any change in your HD lineup since Win2K was installed,
things can get confused and you get one of several such error messages.
Adding or removing a drive or a partition can do it; even plugging or
unplugging a ZIP or other removable drive can do it; changing your drive
info in CMOS can do it...
This KB article might be a good place to start looking for a solution to
your problem:

If that doesn't do it, use Google to search the support.microsoft.com
website for "2000+ntldr"; I get over 200 hits.
