Billpenny,
The XP Home's Setup has the ability to repartition and reformat the hard disk on your computer.
Have a look at this page: http://www.winsupersite.com/showcase/windowsxp_sg_clean.asp
Read the first section for background, and when you get to the second section entitled Step-by-Step: Clean installing Windows XP (Interactive Setup)
follow the steps.
First, physically disconnect from the internet.
If your computer boots from an SATA hard disk, look for the F6 prompt almost immediately and then press F6. You will be asked to provide a driver later. (You mentioned that you don't have a floppy drive, so if you do have an SATA disk whose controller requires a separate driver, this will present a problem beyond the scope of this forum.)
At Step 1 you may be asked if you want to repair the existing installation of XP. Bypass this by pressing ESC.
At Step 5 you will be presented with a list of partitions. Delete all partitions except small unlettered partitions which may be manufacturer-supplied recovery or diagnostic partitions. Since the partitions being deleted contain an OS, you will have to endure several Are You Sure questions.
Once partitions are deleted, make a new one onto which you will install XP Home.
Step 6 formats the partition you made in the file system of choice. Choose NTFS but not quick, unless you have a reason to choose FAT32.
The rest of the Steps and Setup are pretty much a mundane task.
Let us know how it goes...
