The Haynes Linux Manual offers a complete introduction to free, open-source Linux operating systems, and specifically Ubuntu, which is currently the most popular distribution with new users in particular. The manual comes complete with a bootable CD containing the latest available release of Ubuntu Linux. Readers will be able to trial Ubuntu on their computer by running the CD, or install it alongside (or in place of) their Windows operating system if they so choose.
Very helpful, anyone want to learn Linux? This is very helpful if you have some background knowledge in windows and OS, and I feel Linux is a combination of both systems. I really want to build a computer, (and I am starting to), and Linux is a perfect operating system because the amount of RAM it uses is 1GB less then windows, and when running a server, especially a one that needs high performance, like virtual world gaming server, you need all the RAM you can get.
