I have a bootable CD image that I would like to transfer to a USB stick, so that I can boot from it. The Startup-Disk creator doesn't support it. How can I make a bootable USB disk from it? The ISO is quite old so that might be a problem.
You can use UNetbootin
sudo apt-get install unetbootin
Diskimageand browse to the ISO files location.
Make sure that the right USB drive is selected and then hit
This will create a bootable USB drive off the provided image.
