That would be my biggest concern right there. When you do your install, it will overwrite all your puppy files.
If you have access to a XP disk, insert the disk, and reboot to allow the PC to boot to the Windows install process.... Continue through as it does its detecting, and when asked for the type of install, choose Repair(R). This will take you to a Dos C: prompt.
FIXMBR- Clears the Master Boot record of C:. You'll get a warning that all data is about to be lost, etc, but if you're going to be doing a clean install of a new version of Linux, the data is no issue. Choose Y to accept the change
FIXBOOT- Clears the Boot sector and writes a new boot partition. You'll get a similar warning as above when you execute this command. Choose Y to accept.
This should completley erase Grub/Lilo from your system, so there will be no bootloader.
Type exit at the prompt to reboot. Note, if you're dual booting with Windows, the PC will just proceed to Windows upon restarting. If you're not dual booting, you might be some error message. Insert whatever new Linux CD you plan on installing into the drive, and boot to install process. It should reinstall grub or lilo when you do your new install.
Speaking of the FIXBOOT/FIXMBR commands. Does anyone know where to get a copy of those commands, w/o using a Windows XP disk? I figured the commands would be on a FreeDos disk, but it doesn't appear they are.
