I recently tried to install the latest version of Ubuntu on my computer, substituting Windows 7. The installation ran smoothly, but now when I try to boot the system I receive this error message:
reboot and select proper boot device or insert boot media in selected boot device and press a key
The only thing I can do is run the live version via USB, which is what I am doing right now. I looked for a solution in some forums and I decided to run boot-info and post the result of the diagnosis here.
