That's why applications with graphic interfaces are appearing that carry out more intuitive actions like mounting a disk image. A practical example is Furius ISO Mount.
This application makes mounting and unmounting ISO and IMG images really simple. Initially created for Ubuntu users, it's characterized for mounting and unmounting an unlimited number of virtual units in a clean and correct way, creating checksums of the virtual disks and, once used, restoring the system to its former state.
All of this makes Furius ISO Mount a utility that's worth the try!
