Recently, 3 of my friends asked me how to burn a DVD image (the ISO file) to a DVD. Basically, a CD/DVD image (ISO) file is a archive file just like 7z, RAR or ZIP. Unlike normal archive file, a CD/DVD image file sometime contains boot code and it is usually a complete sector-by-sector copy of a CD/DVD.

In this post, you will find out how to properly burn a CD/DVD image. I will use the Ubuntu 9.04 CD image as the example. Latest disk burning software should support ISO burning to disk. The keywords to burn ISO file to disk usually sounds like ‘Write image file to disk’, ‘Burn ISO image’ or ‘Burn image’. You can use your favourite CD/DVD burning application as long as it supports burning from CD/DVD image. In this post, I will use CDBurnerXP, a free CD/DVD burning application for Windows.
