I've got two options for you but would just prefer you try this Bootable CD Guide since you have other computers, you could get the cd and copy it to your hard drive, then run nero and follow that Boot CD guide, you also might wanna find a "boot.ima" file, as this will be what it boots from. The other desperate option you could try(only, if only the first one doesn't work) is you could put your hard drive on one of your other computer, and load it up and go into Win explorer, go to my computer, find your hard drive you just inserted, then right click>format, then you wouldn't have to install over xp Hope that helped!
