Maybe using pendrive and booting his Notebook's USB port. See what the priority boot devices must be, ensuring yourself if it's CD/DVD ROM to boot him.
Try some Debian-based and Ubuntu-based GNU/Linux operating systems if you can.

I changed the BIOS to boot from CD/DVD but all I get is a message to put a boot device in and reboot. It will not recognize the bootable DVD with Debian on it. What else do I need to do to get rid of 10 and put Debian on it? Thanks for your help Maureen
