[SOLVED] Arch won't boot after BIOS update

Motherboard: Gigabyte ga-z97-hd3 (firmware F9)
Arch: UEFI installation using grub as bootloader

After a BIOS upgrade my Arch system does not boot (no bootable partition). rEFInd on a bootable usb-stick sees the /boot/efi partition and is able to boot from it.
So I was able to fully get into the system (for now).
I do not know how or why the bios does not detect the partition as bootable anymore and I do not know how to solve this.

I want to be able to boot again without using the usb stick...

Note:
I found some old installation notes, could this command fix the problem?:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub_uefi --recheck

Likely, some UEFI's simply reset their NVRAM entries on update and you have to add them again.

The command indeed worked. I had no idea that grub-install was actually tinkering with BIOS settings.

Thank you.

It doesn't tinker with BIOS settings. UEFI settings for boot are stored in NVRAM. UEFI != BIOS.
