How to burn an ISO-image into a DVD

You could install k3b too :

sudo apt-get install k3b

( when you create boot-cd in k3b simply drag-and-drop iso-image from above file-window into below window of to-burn-CD/DVD. )

Or use command wodim in terminal to burn boot-CD/DVD like:

( if necessary : sudo apt-get install wodim )

cd /home/$user/Downloads

wodim -v -eject name-of-file.iso

wodim is a command line tool that makes burning iso files to disc easy. These instructions will help you to burn a disc when a Graphical User Interface is not available.

1. Install wodim with the commandsu -c 'yum install wodim'
2. Locate your cdrom drives location with wodim --devices. This should give something like the following:

   [zoglesby@zlaptop ~]$ wodim --devices wodim: Overview of accessible drives (1 found) :-------------------------------------------------------------------------0  dev='/dev/scd0'rwrw-- : 'TSSTcorp' 'DVD+-RW TS-T633C'-------------------------------------------------------------------------

3. Using the output from above identify your drive location. In this example it would be /dev/scd0, and issue the following command to burn the cd.
   wodim -v dev=/dev/xxx speed=4 -eject /path/to/Fedora.iso.
