Thanks for responding, Linney. I started out with a new HP computer with Vista installed. HP was no help at all in setting up the dual booting, and in fact recommended against it. They felt I oughta learn to love Vista. I did find the the APCMag site you referenced, and used it to partition the disk and install XP. When I got to the part about repairing the Vista bootloader, the article instructed me to insert the Vista DVD and use the "repair computer" routine. As I stated before, I don't have the full Vista Disk, and the one HP gave me doesn't have the repair computer capability. I tried VistaBootPro, but there is something wrong with their software. I can't get to the bottom of the system bootloader screen to execute anything. Besides, the option it gives me is to uninstall the legacy(XP)bootloader, which would put me back where I started. Their forum did talk about the oversized screen problem, but their recommendation to re-download it didn't work for me. That's when I initiated this post.
