Well, first you put in fdisk. Then you have to navigate through to delete the partitions. I don't remember which ones you do, but you should be able to figure it out.
Once all partitions are deleted, you need to type format C:. It will ask if you want to or not, press y then enter. It should begin formatting.
After that is completed, remove the floppy, insert the Win XP disc, and restart the computer. You should then be able to get into the XP CD, and then format it properly that way.
