Vista - Error code 80070017 during install

Hi, my dad and I were installing Vista Beta on my laptop and had selected to
install Vista as a clean install. At 30% completion of the install we
repeatedly recieved an error 80070017 message concerning a setup file not
being able to be installed properly.

Is this an error I can get around? The reason I ask is that when I left the
laptop to look for solutions, my dad decided to try to format the hard drive
using the option in the Vista install program. I have lost all ability to use
my laptop and would desperately like to have an OS installed so I can use my
laptop. (The reason I have not reinstalled XP is that I cannot find my
installation CD for it.

If you need further information such as PC spec or a more detailed error
description I would be happy to provide it.

Many thanks
