Hi. I am using Windows XP Pro and am having some problems with it so I want to reformat the hard drive and reinstall Window on it. I backed up my internal system hard drive to an external back up hard drive using Ghost 9.0. I formatted my internal hard drive and loaded Windows XP on it. When I restored my internal hard drive from the back up external hard, it converted back to the previous version of Windows that was on my drive before I reformatted it. What files should I not restore from the back up disk so that it does not revert back to the original OS but does renstall all of my files and folders? Thank you very much.
