|You are kind of stuck. You need a bootable media of some kind. Most people use a CD/DVD. |
Might borrow a usb cd/dvd drive from a friend if the system supports usb booting in bios.Then see the microsoft site on how to use "repair" to fix you xp installation. It will most likely mess up programs but the personal data ought to be there.
Other than that you could see if any friend has a usb bootable OS to be used to recover data.
Lastly is network booting. Get a floppy from netboot.me and see if you can get tinycore loaded over the network to try to access the hard drive.
Might have to use hard drive diagnostic tools like seatools or others.
