Try Safe Mode with Command Prompt only. Then:
1. At the MS-DOS prompt, type cd\windows\command, and then press
ENTER. Where windows is the name of the folder in which Windows is
installed.
2. At the C: prompt, type scanreg /restore, and then press ENTER.
3. Select the previous registry you want to restore, and then press
ENTER.NOTE: A properly working registry has the word "Started" next to the
date.
4. When you receive notification that you restored a properly working
registry, press ENTER to restart your computer.
If this doesn't work you could try a ME boot disk and then try the above:

Outside of this I think you are going to need a ME CD and a working CD drive. Sorry
