Recover UEFI’s grub entry after updating BIOS
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
su -Re-create boot entry
efibootmgr -c -g -d /dev/nvme0n1 -p 1 -w -L "Slackware" -l '\EFI\grub\grubx64.efi'
