I'm trying to format the old hard drive and install win2k on a computer that i just gave to my sister. I set the bios to boot from the cd. I get the prompt that says "press any key to boot from the cd". Whether or not i press a key, it does not boot to the cdrom. It instead boots to the old OS i have installed. It's very weird...it seems like the cdrom just doesn't read the disk after that prompt. What's wrong?
