If you already have an ISO image, go to ‘Tools’+‘CD’+‘Burn CD image’. A window opens in which to enter the location of the ‘Image to Burn’. K3b calculates a check sum and displays it in ‘MD5 Sum’. If the ISO file was downloaded from the Internet, this sum shows if the download was successful.

Use the ‘Options’ and ‘Advanced’ tabs to set your preferences. To burn the CD, click ‘Start’.
