Most HP recovery disks erase the hard drive during the recovery process.
Some have an option to perform a repair recovery rather than a full
recovery. It's very doubtful this will work as you have Pro on the computer
and the recovery disks are Home. You will have to buy the full retail
version of Vista Home Premium, erase the existing Vista Ultimate, and
install Vista Home Premium. This will leave your existing XP Pro
installation intact. If you want to use a Vista Home Premium upgrade disk
then you will have to use your HP XP Home recovery disks which will erase
everything on your hard drive then install the upgrade from within XP Home.
