Another BIOS update from my MSI B550-A Pro motherboard, another loss of all BIOS settings and boot entries…
Here's how I recovered this time as a Slackware bootable install USB-key wouldn't boot.
* Boot from a LiveSlak
* open a Konsole
* become root
#+begin_src shell
su -
#+end_src
* Re-create boot entry
#+begin_src shell
efibootmgr -c -g -d /dev/nvme0n1 -p 1 -w -L "Slackware" -l '\EFI\grub\grubx64.efi'
#+end_src
