I downloaded the Knoppix ISO file, burned it onto a CD, and ran it on my Sony laptop (one with a removable docking bay and 12.1in screen) and it loads up, says it found an undefined video modes or something like that, says Continue or Space to see video modes, if I press either, it starts loading Knoppix and it says that "No Knoppix File System. Dropping you to a (very limited) shell" in red letters. Then it gives me the knoppix command like and about 6 commands. I even tried running Knoppix in failsafe mode. How do I fix this?
