By using linux, you are able to mount an ISO image by the loop network device, which is quite easy. You can do this only as user root. Follow the steps below:

Change to user root:

# su


Mounting the ISO image to a directory or your choice, for example /mnt

# mount -o loop disk1.iso /mnt


Don’t forget to umount the ISO image after using:

# umount /mnt


More about loop device
A loop device is a virtual network device which makes a file accessible as a block device. Loop devices are typically used for CD ISO images. Mounting a file containing a whole filesystem by a loop mount makes the files within that filesystem accessible. The content of the ISO image appears in the mount point directory using above commands.
