Burn your CD or create a bootable USB stick

Once you've finished downloading your file, you'll need to create a CD or USB drive.

Why do I need a CD?

Burning a CD means that you can try Ubuntu without affecting your current system. And you can install it alongside or instead of your system whenever you're ready.

I would like to create a:

CD USB stick

To create it, I will be using:

Windows Mac Ubuntu

Try it!

You can try out Ubuntu before you install it. When your CD or USB stick is ready, you can run Ubuntu directly from your CD or USB without affecting your current system.

Install it!

When the CD or USB stick is ready, simply put it in your computer, restart and follow the instructions that appear on your screen.
