If you have a low-spec'ed computer (64 to 128 MB of RAM, less than 1 GHz processor), you may have difficulty with a regular Ubuntu installation. You may, even if you have a higher-spec'ed computer want to create a minimal installation for other reasons.
Go to the Ubuntu Minimal CD Image page to get the minimal CD.
This guide will help you burn the .iso to CD
Note: a high-speed wired internet connection is recommended for a minimal installation.
On older versions, when you boot up, you may get a boot prompt. If that happens, just hit Enter there.
Select Command-line install
After a short wait, you'll be presented with a couple of easy questions. Use Tab to move between options and Enter to select the option you want to proceed with.
Ubuntu gives you the option to have your keyboard autodetected. I would advise against this. It's a little involved with a lot of guesswork based on what letters you type on your keyboard. It's easier to just select what keyboard layout you have.
More easy questions. If you don't know the answer to certain questions, just go with the default.
Partitioning isn't as scary as you might think it is. If you want to take up the whole disk with Ubuntu and erase everything you have on your drive now, choose the Guided - use entire disk option. If you want to save what you have installed and carve out some space for Ubuntu, choose Manual. You'll have to resize your current hard drive partition and then create a new partition for Ubuntu.
The rest of this tutorial assumes you're using your entire disk. If you need help with partitioning, post a thread on the Ubuntu Forums.
Lots of questions. Just as before, most of the questions are easy to answer. If a question is hard or confusing to you, just go with the default answer.
After you boot up without the CD, log in and you should be at a prompt that looks like username@computername:~$. So in this example, the prompt looks like susan@ubuntu:~$.
At the prompt, type these three commands (unfortunately, you won't be able to copy and paste into the fullscreen terminal, so please be careful to type exactly what you see here; be mindful of the spaces and spelling):
sudo apt-get update
sudo apt-get install xorg xterm gdm icewm menu firefox gksu synaptic --no-install-recommends
sudo service gdm start
You should get to a graphical login screen.
After you log in, you should then see a very basic menu with at least a terminal.
After this minimal install (using Ubuntu 12.04 as an example for these screenshots), the total installation size is a little over 1 GB.
