I have been trying for 2 days now to install Kali Linux on a Dell Optiplex 780 and when it starts I choose the language, country, and keyboard layout but then it keeps saying unable to mount the cd. I have used rufus to create a bootable installation. I have searched and searched for answers and have not found one. I am asking here to see what the issues is and how can I fix this so that I can install Kali. Please if any one can help would be great. Thank you
