It is possible to run Ubuntu on your computer without installing anything because the Ubuntu disk is something called a Live CD. When your computer boots up while you have the CD in, you are given the choice of either booting from the computer's hard drive or running Ubuntu by Live CD.
To do this:
- While your computer is on, insert an Ubuntu CD. You can get these CDs many ways, including downloading Ubuntu and burning it onto a disk, buying a CD from the Canonical Store, maybe getting one from a friend, or finding one at a local computer store.
- Restart your computer if it had already booted from the hard disk (your other operating system started) and select the disk drive in your boot manager.
- At one point while the computer is booting, you should see an Ubuntu boot screen. To run Ubuntu, select "Try Ubuntu"
- Ubuntu will start as normal and you can use it like a normal user, but files will not be saved when you close the session. To install Ubuntu, you can double-click "Install" on the desktop and follow the steps.
Burning a Live CDEdit
This section will take you through the steps of burning your own Live CD.
- Firstly, you will need the ISO file used to run the system downloaded from Ubuntu.com. This can be downloaded from here.
- Next, you will need to insert a blank CD into a working disk drive.
- You will also need a program able to write ISO's to a Disk, if your unsure if you have one or not, use Infra Recorder.
- Now navigate to your ISO in your selected program and click a form of ok button. Your disk should be easy enough to figure out from here.
- Once writen to the disk, you are able to use that CD to boot from this CD.
