|"I'de just like to know how to clear all of that out and install a windows home edition to it"|
That's not what you originally asked.
Have you ever installed Windows from scratch before? If you have a WinXP Home Edition disc & the product key, all you need to do is boot off the disc, reformat the hard drive, then proceed with the installation. You will need to install the device drivers, SP3 (if it's not on the disc), all the Windows Updates, an anti-virus program (I recommend Microsoft Security Essentials), & whatever other software you need.
