[SOLVED] BIOS Update - ArchLinux does not boot

Hello everyone,
I had a perfectly booting archlinux.

I am on a gigabyte b450 aorus pro and updated the bios.

Now I can not boot into my archlinux anymore.

It keeps telling me "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"

- Checked boot order
- Checked UEFI/LEGACY settings

Any ideas? Thanks!

Re: [SOLVED] BIOS Update - ArchLinux does not boot

A lot of UEFI motherboards wipe their NVRAM entries when you update the firmware.

Boot from live USB, chroot in, and restore your bootloader entries.

Worked. Thank you.

For those who came here and have the same problem:

1. insert boot cd
2. mount </dev/rootpartition> /mnt
3. mount </dev/efipartition> /mnt/boot
4. swapon </dev/swappartition>
5. arch-chroot /mnt/
6. grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=grub

Greetings
