CD/DVD to .iso file on hard drive using Brasero

OBJECTIVE:

Backup restore system CDs/DVDs to an .iso file using Brasero.

STEP 1:

Run Brasero.

STEP 2:

Click Disk copy.

STEP 3:

In the Select to disc to write to drop down box, change this to Image file. This will tell Brasero to save the file as an .iso file instead of burning to a new disc.

STEP 4:

Click Copy.

STEP 5:

Perform MD5SUM on .iso file and original CD/DVD to ensure you have a good copy.  Open terminal (see example below).

user@zorin:~$ md5sum HP_S7620N-DVD01.iso
