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 finished installing Ubuntu 11.10 64 bit on my desktop and it asked me to restart the computer to complete the process. I restarted and...nothing came up...just a black screen with a white dot...and I have absolutely no idea what to do now :-(
I started to read the posts here, but got completely lost and have no idea which solution is appropriate for my problem as I don't get any option here, it boots directly to this black screen, no recovery option, no grub, no cmd, nothing...just the black screen with the blinking dot :-(
Thanks a lot for the advise, but the shift key did not bring up grub. I am getting some advise and it seems that the problem is connected to my video card. I will keep you guys posted once I try this other solution I was offered, let you know if it works, etc.
Problem solved - thanks to post 20! And thanks for pointing it out!!!!
A more detailed explanation:
I decided to try the post 20 option (upgrade from ubuntu 11.10 to ubuntu 11.10), to see what happens. While I was doing this option, just before the installation started, it popped a message saying that I had no swap and it offered me to go back to the partition part to make a partition for the swap. I did go back and found myself in the advanced partition menu of the install CD. Note that the previous times that I installed, I simply chose in which disk I want to install ubuntu (I have two in my desktop, one of 1T and one of 160G). I chose the 1T all the time and did not go into the advanced partition thing because I wanted a simple install, ubuntu on all the 1T disk. Now that I was forced to enter there due to this swap message, I noticed that on the previous installation (the one that did boot into the black screen), it somehow chose to install the MBR in the 160G disk instead of in the 1T disk, which is the one I had always chosen.
Anyways, I made the swap partition, chose the 1T for the MBR and proceeded with the upgrade ubuntu 11.10 to ubuntu 11.10 option. It took more than 2 hours to complete the installation (as opposed to 20/30 mins on previous times) and in the end, low and behold, it booted OK.
Now I don't know if what solved the problem is the fact that I corrected the location where MBR should be installed OR the ubuntu 11.10 to ubuntu 11.10 upgrade option OR a combination of both.
