Unable to locate "MSDART.dll" when installing SQL 2000

I successfully installed SQL 2000 on my Windows XP machine here at work, but when I tried to install the same thing on a Windows 2000 Machine here at work, I get an "Unable to locate C:\WINNT2\Program Files\Common Files\System\
ADO\MSDART.dll" error message half-way through the install. After doing some checking I found out that C:\WINNT2\Program Files\Common Files\System\ADO\MSDART.dll didn't actually exist. The reason being is that at one time this was a Dual-Boot machine at one time.  C:\WINNT2 did exist, but I had to create the Program Files folder, Common Files folder, System folder, and ADO folder. I then placed the existing copy of the MSDART.dll in that directory, and still no luck.  Formatting and reinstalling Windows on this machine is not an option. Do I need to modify the boot.ini record or something? Note: C:\WINNT does NOT exist. C:\WINNT2 is the valid WINNT folder. The first installation of Windows 2000 was deleted, but evidently it was deleted improperly.

The reason I ask about the boot.ini is that when the machine boots, it sees two installations of Windows 2000. Only one is actually on the machine, but it gives the option of both. If I need to modify the boot.ini, what are the best steps to take to modify it to show only one existing instllation? Thanks!
