do not know what you mean by leave something behind when using a partition program.
normal boot menu , FDD is floppy disk and LAN is a network boot option

read above on how to boot from these, it does not look like you have a usb boot option you would have to see your manufacturer's website for your specific machine to see if you can boot from a usb device

you should also read above to see if your pc is on the list of supported devices, and if the pc was running xp, it is unlikely that it can support win7 or higher without some major hardware upgrades.
=================
if the supplied disks are reinstall media and NOT recover media you can use it to setup xp, since you are given that option during setup, if you were not given that option then the discs you have are not install media, just recover media. and you would need an install cd to actually install xp, and the updates from microsoft updates up to 2014, are still available, you need sp3 and ie8 installed to access the windows update site.
=================
if your pc supports the neverware chrome program (check the website above), you should be able to download the ISO and burn to a cd/dvd and then boot to that.
