Can't get Live/Install CD to work. What am I doing wrong?

I've had errors in the past from the bios whitelisting certain Linus distro.
10.04 worked but 11 didn't.

There was a setting in the bios that appently has to do with Windows.

Also I always hit del to enter the bios and pick boot override

Well, stupidity and a very foggy brain have helped to complicate this much more than it needed to be. I was using too small of a USB stick. Almost large enough, but not quite! There was no warning and no action. I used a larger USB stick and it worked. Sorry for the trouble! But thanks for the assistance.
