Help with operating systems

Hello,






I accidently wiped my whole computer out and i currently have NOTHING on there to work with at all to get it back up and running. Is there anyway possible to get the windows xp back on my computer with out the disk? I do have my product key on the back of the computer but i do not have the windows full version disk to install it. I have a windows anytime upgrade but not the full version. Or can someone help me get started? I have been working on it for days straight noone can seem to help me because my waranty is up. I do have another computer available to use for like transftering things back on to my broken pc but i cant seem to get that working either. Any ideas? Thanks so much
