Unable to boot after BIOS upgrade

Support
,
1

I was experiencing system freezes quite frequently while running Manjaro. I tried updating the BIOS (Gigabyte B450M DS3H) and was no longer able to see /dev/nvme0n1p1 as a boot option.

I have a dual boot setup with Manjaro on /dev/nvme0n1 (with a separate boot partition) and Ubuntu on /dev/sda1 (which includes /boot).

nvme0n1     259:0    0 119.2G  0 disk
├─nvme0n1p1 259:1    0   300M  0 part /boot/efi
└─nvme0n1p2 259:2    0 118.9G  0 part /
sda           8:0    0 223.6G  0 disk
├─sda1        8:1    0  29.8G  0 part 
└─sda2        8:2    0 193.8G  0 part /mnt/media

I was able to boot from /dev/sda1 into Ubuntu. I ran grub-update and that picked up my Manjaro installation. I was able to load grub from /dev/sda1, but when I selected Manjaro the system got stuck and Manjaro wasn’t loaded.

I booted from Manjaro-on-a-stick and its grub menu showed me an option to scan for other EFI installations. I found my Manjaro installation there and was able to load it without hassle.

I have tried running a system update (which installed a new kernel) and have tried grub-update from my Manjaro installation, but nothing has allowed me to boot from /dev/nvme0n1 directly.

Any tips or advice welcome. Thanks :+1:

Hello @commander_trout :wink:

  1. Manjaro’s grub version is customized and not compatible with Ubuntu’s grub. Ubuntu will not be able to boot Manjaro, but Manjaro can boot Ubuntu.
  2. If you want grub for Ubuntu and Manjaro, then don’t share one EFI Partition, but create one for each Distro and install grub there separately.

Thanks for the reply @megavolt

I wasn’t aware that Ubuntu grub could not boot Manjaro. I had thought all grubs were made equal. I could swear I’d booted Manjaro from Ubuntu’s grub before. That would explain why that path hadn’t worked.

In fact, I’m prepared to blast Ubuntu away (was only there for Steam), so I don’t care much about the dual boot. How do I rescue Manjaro’s /boot/efi though? It’s the partition that doesn’t appear to be bootable…

@freggel.doe Thanks for that link. It talks about needing to be chrooted, but I am actually able to boot my Manjaro installation using live USB grub. I assume that I therefore don’t need the chroot and can just follow those steps to reinstall grub and generate its config.

I used the instructions at the link posted by @freggel.doe and was able to get my system booting again.

I used grub from a Manjaro live USB which was able to discover my (non-booting) Manjaro installation and boot it successfully. Once I was running my local installation, I ran the following commands:

$  sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
$  sudo grub-mkconfig -o /boot/grub/grub.cfg

:information_source: Because I was actually running the installation I was trying to repair, there was no need for a chroot, but I did need to sudo the commands.

:warning: grub-mkconfig gave me a warning (warning: unknown device type nvme0n1), which I ignored.
