Hi

Once this error is received it's very difficult to overcome
It's basically some updates done by MS on your computer that requires you to possibly manually delete certain files and continue the repair.

I'll post the Repair proceedure here too: Vista Repair:
http://vistasupport.mvps.org/windows_vista_repair_options.htm

Possibly a much easier alternative would be just to start again (format and install Vista clean) As long as there are no user data to backup.

If you do have your own personal data on the HardDrive, then it may be easiest to actually mount your HardDrive in another computer, as a secondary drive (even through a USB adaptor) and then fully backup using that other working computer.
Then once all is safely backed up. Install Vista clean

I hope that would be an option that could try.
