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 (F2 key if you are on the screen announcing the issue or F12 at restart)
  • In the first General panel, select Boot Sequences. In the list of Boot options, the UEFI Radio button must be selected, click on Add Boot Option
  • Browse the tree, 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 Security panel, select UEFI Capsule Firmware Updates and uncheck Enable UEFI Capsule Firmware Updates
