You haven't supplied any useful info about your system but if it's a custom built system rather than OEM (Dell, HP, Gateway, etc), the Del key is generally the key that will get you into the BIOS. If you have an OEM system, a message usually pops up on the boot screen for a second or 2 - something like "press F1 to enter setup". That's the key you need to press to get into the BIOS. However, if you're using a USB keyboard, that may be a problem. Change the boot order to floppy-CD-HDD.
Why do you want to run FDISK? And how do you plan on running it? It's not on the XP disc. You either have to run it from a bootable floppy such as a WinME startup disc or a bootable CD that contains FDISK such as the Ultimate Boot CD. You still need to have the boot order configured correctly. If you get that figured out, all you need to do is boot from the XP disc, delete all partitions, create new partitions, format, then proceed with the installation. You'll lose everything though, are you prepared for that? And do you have all the drivers & software ready to reinstall?
