Ubuntu UEFI Won't Reboot

[Vincent Olivier]

Hi,

I can install Ubuntu (Server LTS 16.04.1) in graphic UEFI mode with the official ISO install media. But when I restart the machine without the install media, I get:

Boot Failed. EFI DVD/CDROM
Boot Failed. EFI Misc Device

I’m sure there is an easy modification to a plain text file in the /boot partition of the block device that will fix this. Anyone knows how to make this work? If not, where can I get more information (log) on this?

Thanks!

Vincent
