I swear I followed the instructions character for character. The CD calls itself "Ubuntu 11.04 amd" and has 19 files/folders visible upon opening.
When I try to boot from the CD, I get to the deep purple screen with the the <symbol?>=<person> thing at the bottom, followed by a black screen with a flashing underscore in the top left corner. It stays like this indefinitely. What am I doing wrong?
