BIOS Update That Will Break Boot

User Support

I have a Framework Laptop running Qubes 4.1, and I want to update its BIOS to solve a power problem. Unfortunately, Framework’s latest update is known to reset UEFI settings, including boot entries.

Can anyone recommend a procedure to back up and restore Qubes’s boot entry before I try this update?

If you use uefi :

  1. get a qubes os media installation.
  2. boot to qubes os rescue mode.
  3. skip to shell.
  4. [shell] : efibootmgr -v -c -u -L "Qubes OS" -l /EFI/qubes/grubx64.efi -d /dev/nvme0n1 -p 1
  5. reboot

change -d <which drive?> and -p <which efi partition?>.

if you want you can make sure first by issuing efibootmgr -v in dom0

Thanks! Your instructions worked a treat, and your guesses for the device name and partition number were spot on!
