After several trials and errors it seemed as though the installation for Ubuntu was finally complete. I rebooted up my computer and received the prompt for the OS, and selected Ubuntu. It spat out a few command lines and continued with a peachy toned gradient. Soon after I was asked for a user name, but I didn't put anything before it cut me off on a timed prompt then led to a black screen. All that was do-able was to move the mouse around. I reboot the system again and it gave me error 21. I tried restarting again and then selected recovery, and restarted once more. I don't have any specifics at the moment, but i may be able to give some.

Here is the tech. background:
Attempting to boot on 60 gig partition portable hard drive (out of 250 gig)
booted up on CD.
