Suse, Ubuntu and Knoppix are common names of bootable CDs that let you run Linux without installing. Also a great way to sniff out which distro supports your hardware without installing Linux.

I am a complete beginner with Linux, and I plan on installing it, but I really need some help with it. I don't really know what to do. As I said, I am a complete beginner, and thus, I have no idea how to install and what to do once I install it. How should I install it, where should I go, which distribution should I get. How to install it, how to partition my hard drive for it. Also, once I get it, I've heard that you need to use commands a lot for accessing your daily needs. How do I know what those commands are, and what to do with them? Are there any books or any other resources available to help me as well? I need as much assistance as possible.
