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 using fedora 11 and just wanted to move to fedora 12.After doing search on google I found the commands to upgrade it.
1- yum update rpm
2- yum -y update
3- yum install preupgrade
All the updated went on smoothly but on rebooting the system after executing the "preupdrade" command, system is not able to boot.
Below is the snasphot of the error that i am getting:
