[SOLVED] Can't boot Arch Linux after BIOS upgrade

I have an EVGA Z170 motherboard in my Arch Linux machine and I just updated the BIOS on the motherboard and the BIOS can't see my drives anymore. Arch is installed via UEFI mode. The BIOS can see my drives legacy BIOS mode for some reason but not in UEFI. Do I need to do something in my Arch install in order to get it boot again, e.g. rescue disc etc.?

Re: [SOLVED] Can't boot Arch Linux after BIOS upgrade

It's possible that the firmware upgrade (UEFI motherboards don't have a BIOS) deleted all of your nvram entries.

Try booting from the Arch installation media, chrooting into your system, and reinstalling your bootloader.

You mean reinstall the uefi partition I originally made and reinstall grub?

How do you reinstall a partition? Question is nonsense, slithery's advice is very specific.

Sounds like you mounted the wrong partition

Yeah, I made a mistake there. I have chrooted into my machines root and I am trying to reinstall grub like I did originally with

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

but I get this error

grub-install: error: /boot doesn't look like an EFI partition.

Re: [SOLVED] Can't boot Arch Linux after BIOS upgrade

You have to mount all of the relevant partitions before you chroot, not just the root partition.

You probably didn't mount your EFI partition.

Exactly my mistake from before. I had mount the boot partition in the wrong place. After mounting it correctly I could run grub-install and grub-mkconfig and my machine was to boot again into Arch Linux. Many thanks.
