Wrong question, you should have asked how to download and burn it correctly. It looks like you guessed that you knew what you were doing and chose an option from some burning software to make a bootable CD. You got a bootable CD, but not what you wanted. Start here: http://www.knoppix.net/wiki/Downloading_FAQ

If you need more help there are a lot of discussions in the forums about how to burn the iso properly from different software packages. Look around a little, they are easy to find. Two things I'll mention now: check the md5 sum - this is extremely important! And burn at a slow speed, like 4x (at least until you get your first working copy).
