ca4nkashun, this is a very easy fix.
All you need to do is copy the ntdlr file from your OS cd/dvd to c: drive.
your windows should be fine after that.
Depending on your situation, you might have to load savemode first before hand.
Press F8 after post to do that.
All Ntldr is, is a file that's needed for windows to load. It's always found on the original cd/dvd as well.
