How to burn an ISO file to CD using Ubuntu.

Ubuntu

1. Insert a blank CD into your burner. A "CD/DVD Creator" or "Choose Disc Type" window might pop up. Close this, as we will not be using it.
2. Browse to the downloaded ISO image in the file browser.
3. Right click on the ISO image file and choose Write to Disc.
4. Where it says "Write disc to" you may have options such as "File image" as well as your CD drive. Choose your CD drive. Your CD drive may show as something like "BD-MLT UJ-210S"
5. Select the write speed. If you are burning a Ubuntu Live CD (one that you may want to boot from), it is recommended that you write at the lowest possible speed.
6. Start the burning process.
7. After burning completed, verify that your CD contains multiple files and folders and not just the ISO file. This way you will know the process was performed correctly.
