Title:
  Drops to grub> prompt in Secure Boot Mode

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  I've Ubuntu installed with Windows 10 in dual-boot. When I run the PC or when I restart it this happens:
  1. I see the motherload screen.
  2. A grub command line appears.
  3. I type 'exit' to halt it.
  4. The motherload screen appears again.
  5. Finally the grub where I can select the OS shows up and all runs properly.
