Why I can not boot from optical drive?
I want to install an ubuntu or a fedora on my pc. But when I change the boot option to boot from optical drive first, it doesn't boot with a ubuntu or fedora dvd inside. I only can install an XP cd. I checked and re-checked the linux dvds. Thus I am sure that they are okay. With fedora inside, it shows error message like "ä port is slow to respond..." or something like that. With ubuntu inside, it shows a blank screen. Why?
