Step 1: Installation of VGA driver

You may skip this step if you have already installed restricted display drivers from Ubuntu's PPA repository. This step is optional even with a default Ubuntu installation. I recommend to proceed with Step 2 and let Ubuntu system will attempt to detect your VGA card and install appropriate VGA drivers for your card automatically. If that fails come back to Step 1 and do it manually as described below.

Installation of nVidia restricted driver

First add ubuntu PPA repository:

$ sudo add-apt-repository \
ppa:ubuntu-x-swat/x-updates
$ sudo apt-get update

Introduction

My restless effort to promote a Linux operating system and encourage its usage among other "PC" users made me this time to tackle a core topic of this effort and that is dual boot Linux Operating System and MS Windows XP Pro. I really do not expect windows users to switch from MS Windows to the Linux from one day to another, but I rather expect a slower and gradual transition with less headaches and without productivity losses.

There are already plenty of excellent articles in regard to this topic. However, I do still see Linux forums flooded with simple basic questions on how to dual boot these two operating systems. I see users coming from a MS Windows environment completely lost when it comes to a UNIX File System Hierarchy Standard (FHS), partitioning using EXT3 file system and navigation with simple "cd" command. It is very hard for them to let go of an idea of C: and D: drives. In recent 2 or 3 years Linux operating systems and its installation has improved in such a manner that I do not see a problem for a NON-IT person to install its own fully functional and productive version of the LINUX on his "Designed for Microsoft Windows XP" notebook.

Despite my believe I have decided to write this Linux-Windows dual boot "howto" for new Linux enthusiasts. In fact, I have had a friend who has no IT background to helping me by following my steps in this tutorial and believe it or not, he could install his own dual booting system without any problems.

Be aware that we are not going to describe all installation steps for both Linux and Windows installations in this article, only those steps which are necessary to accomplish this task.
