Well...what I see when I look at your original or other thread...is a system that has a situation that prevents booting.
It's diagnosed by Windows as "registry file failure"...but what they don't tell you is that any number of things will be diagnosed in that manner.
That being the case, I suggest reinstalling Windows anew...after destroying the current partition.
You can read about the complexity at http://support.microsoft.com/kb/822705
Budapest has already tried to take you through procedures that would be short of a clean install...and that was unsuccessful.
Edit: If you assume that there is something wrong with the drive itself which created the registry problem cited...then the thing to do would be to run the hard drive manufacturer's diagnostic on the drive.
