I went and redid the entire install. This time I just went to the Knoppix root icon, the one with the little penguin and typed 'Knoppix-install' and then went through the motions. When I rebooted, there appeared my choices between the Windows OS's and Linux/Knoppix.
I was told several different things to type at the shell but I'm not sure if all were right in some way or maybe someone left a word out or whatever. Also, the first time I was using the Clam shell icon to get to that shell and the second time I used the penguin icon to go to the root shell. I'm still new to this so it's a bit hard to explain still. The short of it is that I'm in and now I can set about learning to do things with the OS.

Thanks to everyone who has been helping me along!
