The downloaded program will tell you to burn the downloaded program. To do this, you will need a new burner program called CDBurnerXP.

Select the ISO image by clicking on the "Browse" button and going to your "Downloads" folder. Select "dban-2.2.6_i586" and click "Open." Now click "Burn ISO" at the bottom of the screen.
