How to Install Ubuntu via "Live USB method"

Most of newer computers/laptops can boot from USB. A Live Session  (Live USB, also called a Live Desktop) is one of the many methods of installing Ubuntu. It is a "temporary" method of installation. When you run a live session, any changes made to Ubuntu (like downloaded applications, Software Updates, etc.) are lost whenever you restart your computer. This is the case for a Live CD.


However, you have the option of enabling "persistence", meaning you can keep the changes you made to your current live session even after you restart your computer. This is made possible by the Universal USB Installer, a small file that allows you to configure your downloaded Linux-based ISO so that it can boot from a USB. In the Universal USB Installer, there is a small tick box to enable "persistence". However, it is only able to keep changes for a maximum of 4GB (that is the current limit of "persistence").

On both the CD and USB methods, upon installation you will see an icon in your computer's desktop that says something like "Install Ubuntu 10.04". This icon is available so that you can proceed with permanently installing Ubuntu, after you have enjoyed your live session.
