oh.

check that the cd is the first boot device in the bios.

Put in your windows xp disc.

when the computer boots you will get a message "press any key to boot from the disc"

press the "any key" quick and yoiu will see the installer.

It should ask you a couple questions and choose the recover console (not the repair installation using a floppy question)

can't think of it off hand

the cd should boot to a dos like prompt asking you for admin password
