Burning DVDs and system backup
The CD can also boot from a customized DVD which has almost 4.6 GB of free space for backed-up files. This makes it good for storing all the information that is needed from a hard drive and then formatting it. To burn the DVD, one has to burn the image file first and then add all the separate files as well as folders. This should not affect the general way in which the DVD works.
