How to burn a bootable CD or DVD

A bootable disc runs independently of the operating system on your computer. For a example, if you boot your PC through a bootable "live CD" for a Linux distribution, you can test that distribution, and install it you wish. To create a bootable disc, you must download its ISO file (disc image), and then burn it (copy it) to a writable optical disc (CD or DVD).

Note: Usually, you won't need a permanent copy of your disc image. Therefore, to conserve Earth's resources and save your money, you should use a read-and-write optical disc (CD-RW or DVD RW).
Downloading an ISO file - To download an ISO file, do the following:
  1. Go to the website from which you wish to download an ISO file.
  2. Download your selected ISO file, for example, you might download a distribution of Linux, such as Ubuntu, Linux Mint, or Fedora.
  3. Burn the ISO file to an optical disc according to the section below.
