Issues on Ubuntu✯

PC boots but stops at Boot - Nov 2020✯

Observed on Ubuntu 18 following a firmware update

Updating the BIOS via Linux broke the UEFI entries and the machine can no longer find the correct path to boot properly

Resolution

  • Boot into BIOS (press F2 if you are on the screen announcing the issue or F12 at restart)
  • In the first panel General, select Boot Sequences. In the list of Boot options, the Radio button UEFI must be selected, click on Add Boot Option
  • Browse the directory, choose Ubuntu then the file shimx64.efi for a secure boot mode (grubx64.efi for a normal mode)
  • Put this new entry first in the boot order

While you're at it, to prevent the issue from recurring...

In the BIOS panel Security, select UEFI Capsule Firmware Updates and uncheck Enable UEFI Capsule Firmware Updates
