Making an ISO from CDROM

To make an ISO from an existing CDROM is easy, do it like this:

$ dd if=/dev/cdrom of=/tmp/NameOfISOFile

if= stands for input file, of= for output file. Your cdrom device is a file according to the unix philosophy.

The image of the CD is then in the file /tmp/NameOfISOFile

Now you can loopback-mount it or burn it.
