After which nothing else happened, why didn't KNOPPIX run?.
Because you burned it to a 800MB CD, using the boot-able option in Nero Express.
In other words, you burnt it incorrectly.
From Nero Express (at least the version I've seen, but I hate and refuse to use the "express" version of Nero), you want to use the "Disc Image or Saved Project" option. Pay no attention to the bootable option, do not use it. If you burn the image correctly it will be bootable. Also you made no mention of checking the md5 sum, or of burning at a safe and sane speed.
