On Linux systems, if your DVD drive is not accessible to your operating system, mount the DVD drive on your system.
Create a folder to be the mount point for it:
$ mkdir /dvd
Mount a DVD drive using the command:
$ mount /dvd
If your system requires that you have root privileges to mount a DVD drive, these commands work on most systems:
$ su root # mount -t iso9660 /dev/dvd /dvd
To enable nonroot users to mount a DVD drive, include the exec option in the entry for DVD drives in your /etc/fstab file, as in the following example:
/dev/dvd /dvd iso9660 noauto,ro,user,exec 0 0
This option is often omitted from the /etc/fstab file for security reasons.
