Step one:

Say you have a 40GB hard drive. Install Windows choosing 20GB (or greater, but keep at least 10 GB for ubuntu). I am not giving screen-shots for the Windows installation, because i guess that everyone knows about that. The setup procedures are well explained there anyway, but if you have any problems, post a comment, I shall edit this article.

Step 2:

Windows is installed. Now boot on your Ubuntu 8.04 CD in Live CD mode and launch the install icon that is displayed on the desktop.

Step3:

Enter your Time Zone settings:

Then, your Keyboard Layout settings:

Step 4:

This is the most important part. I will discuss the manual partitioning to avoid dramatic, irreversible cases where you lose everything in your other partitions. So, choose manual partition in the list:

(Note: The rest of the tutorial refers to Manual partitioning.)

Step 5:

Create three partitions out of the<i>free space</i> you can see.

One will be swap (set it to 512mb-this is more than enough)

The other one is a small ext3 partition (put it 50Megs) and mount it to /boot (Very important to do that!!)

Then the rest will be all the free space available; use ext3 as file-system and mount it to ‘/’

Step 6:

Proceed with the installation as you would normally. The most difficult part has been done. On reboot, you will notice a nice and beautiful Boot list.
