Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have been running winxp and ubuntu 10.04 for a year or so and when I start my computer, it used to have only 3 or4 choices, now it has 8-10 choices. A lot of them are different versions of recovery mode. What do these mean and is there any way to have just the choice of a couple...winxp or ubuntu. Also can the default be changed?
The mass of entries is caused by old kernels. When you get a new kernel via the update function then old kernels aren't removed. Remove the old kernels you don't need anymore with your package-manager and run
Do a search for linux-image in Synaptic, and the kernels should show up. They have version numbers, like 2.6.32-28, 188.8.131.52, and so on. Important is the last number, newer kernels have higher numbers. Keep the newest kernel, delete the others. If you get a new kernel when updating, try it for some time, before removing the old, so that you have a backup-kernel in case of failure.
Looks like I messed up again....I removed them and now get an error message at start up, but after a few seconds it loads and starts. I checked all updates and no broken packages in synaptic manager...any suggestions, or is a re-load needed?
