Follow these instructions to create an ISO image from a CD or DVD.
- Insert CD or DVD.
- Run Terminal.
- Run the following command:
cat /dev/sr0 > cd_ISO_output_name.iso
- Another command that may work is:
dd if=/dev/cdrom of=~/cdrom_image.iso
In Ubuntu, you can use the Disks utility to find your drive ID name. In the example above, it is sr0.
The resulting ISO image should show up in your home folder, but you can choose any destination you’d like by placing the path before the file name, such as /home/Desktop.
To test the ISO image, double click on it and view its contents.
