[Bug 1796260] Re: UEFI installation alongside BIOS installation: System fails to boot with cannot find a valid boot entry

[Steve Langasek]

** Description changed:

- Ubuntu Cos;ic Desktop 20191005
+ Ubuntu Cosmic Desktop 20181005
  
  Test Case:
  1. Boot in BIOS mode and install on entire disk
  => Verify that the system boots
  2. Boot in UEFI and perform a new installation alongside previous one
  => Verify that you can boot to the new system
  
  Actual result
  It fails immediately on boot with a message from the uefi firmware like "Cannot find a valid boot entry" (its very brief because the system reboots immediately in a loop)
- The BIOS installation boots fine if I switch back to BIOS mode. 
+ The BIOS installation boots fine if I switch back to BIOS mode.
  An UEFI installation on entire disk boots fine.
  
  Log files of the UEFI installation attached.
  
  The EFI partition is created and its content is:
  .
  ./EFI
  ./EFI/ubuntu
  ./EFI/ubuntu/grubx64.efi
  ./EFI/ubuntu/shimx64.efi
