I think, we have to stop here and I'll ask you to post your issue under "Windows 2000" section.
HJT forum has very limited access and it's mainly used for dealing with infections.
You'll get more attention at Windows section.

When your computer is bootable again, please, return back here.

will do.
Cheers.
