Solved: Problems installing Ubuntu

After hearing so much about it, I recently sent off for and received the Ubuntu 8.04.1 LTS Desktop Edition operating system.
I have a laptop Compaq series pp2140. 1.3GHz Athlon processor, 512Mb Ram, 30Gb Toshiba hard drive. Windows XP professional. I want to install the Ubuntu system along side windows XP.
Before hand I defragment the hard drive in Windows XP and made sure there was plenty of spare room on my hard drive. The laptops 30Gb hard drive is partitioned into two parts.
C: part which is holds the window xp operating system is 20Gb in total and has 11.8Gb free space.
D: part is 8.4Gb in size all of which is free space.
I booted my laptop with the Ubuntu CD in the tray and the Ubuntu operating system loaded and started correctly.
To install the system I followed the advise on the following site:
http://news.softpedia.com/news/Installing-Ubuntu-7-10-68645.shtml
I double clicked the install icon on the desktop. Proceeded through the first 3 steps without problem.
On the fourth step there are three choices on how to partition the hard disk.
1. Guided – use entire disk.
2. Guided – use largest continuous free space.
3. Manual.
When I select the second choice as is recommended by the above guide I get the following error message:

Is my hard disk too small to install Ubuntu? Any other advise on this would be helpful as well.

 

It does not matter I have found out how to do it.

 

Other people might have the same problem. How about sharing the solution?

 

Here is a little manual I put together for myself, should I need to install Ubuntu on my laptop later on and have forgetten how to.

If anybody needs more details just say so.
