Go here Download and install procedure of Active@ KillDisk Free make a floppy disk or burn a cd.
put it in and try to boot to it. if it does not boot then we will need to change the boot order in the bios. usually at the beginning of the boot you will see "press f2 to enter the bios" somewhere towards the bottom. when you get into the bios you will need to navigate to boot cycle.
something such as
First boot \floppy
Second boo\t cdrom
third boot\ hard drive
Change the first boot to Floppy save and exit. (depending if you put killdisk on floppy or cd, if you put it on cd make first boot cd rom)
put killdisk in and start the computer. once it boots up top left you will see storage device (your hard drive) pick it press f10 type in the little saying and it will format. after format put xp cd in and start computer it will go to the install.
note that if you FORMAT, and data on the HDD will be lost.... It sounds like he is just wanting to re-install XP...
