jamato323,
Your HP Pavilion should have come with a Vista recovery partition pre-installed. They have detailed instructions on their web site on how to do a complete recovery of the operating system using the recovery partition. I would have to know the exact model number of your computer to give you a direct link, but just got to the HP support web site and search for "reinstall Vista on Pavilion" or find your model number and then select troubleshooting and recovery.
If you go here, they can automatically detect which model computer you have and take you to the correct support site for your computer:
