If you have the iso there, you should be able to mount it as root this way:
- cd into the relevant directory where the iso resides
- mkdir iso_dir
- mount -t iso9660 -o loop <isofile.iso> iso_dir
Now you should be able to see the contents of the iso in iso_dir/, cd into it, look around, read the install or readme files and proceed accordingly. Maybe there's an installation script inside or whatever. I don't really know.
To unmount it you'd do "umount iso_dir" once you are done. Mount and umount requires root privileges in this case.
Alternatively, you might want to install fuseiso if your distro supports it.
If you have fuseiso, the three steps above will only be two:
- cd into the relevant directory where the iso resides
- fuseiso -p <isofile.iso> iso_dir
Then "fusermount -u iso_dir" to unmount it. This doesn't require root privileges.
