Cannot start Endeavour since Bios update

[Bussiereg]

Hello, I updated the BIOS (through my Windows partition) and since I cannot boot through Endeavour.

When I tried, I get a grub error.

the closest I found was:

EndeavourOS bootloader missing after BIOS update (dual boot)

Hello everyone, I recently installed EndeavourOS and I am loving it. I keep windows (different ssd from linux) mostly for gaming and sadly, yesterday my Legion 5 Pro decided to update the bios and now I cannot boot into endeavouros. I tried setting the boot order but my linux ssd shows as windows bootloader and thus I cannot set it from the bios. I already downloaded and flashed a usb drive so that I will try to fix it from there. Could you guide me through? I saw some related/similar issues but…

So when I check
sudo parted -l

Number Start End Size File system Name Flags
1 1049kB 274MB 273MB fat32 EFI system partition boot, esp
2 274MB 290MB 16.8MB Microsoft reserved partition msftres
3 290MB 659GB 659GB ntfs Basic data partition msftdata
5 659GB 1020GB 361GB ext4 endeavouros
6 1020GB 1022GB 2147MB linux-swap(v1) swap
4 1022GB 1024GB 2097MB ntfs Basic data partition hidden, diag

So it shows that my EOS partition is /dev/nvme0n1p5
while my EFI is /dev/nvme0n1p1

efibootmgr gives me:

please note that on the boot, the partition shows as “opensuse” but it’s EOS.

I manage to follow instruction until the chroot (which is not clear) and after the systemd-boot.

Then I got lost.

[Bink]

In your BIOS, make sure you have the correct boot order set, as well as secure-boot and fast-boot
̶e̶n̶a̶b̶l̶e̶d̶ disabled. These things may have reverted to defaults after the BIOS update.

Edit: I had originally pointed to our buddy @cactux’s post here regarding boot-loader repair, but realised it was for systemd-boot, not Grub.

[Bink]

If adjusting the BIOS settings fails to resolve the issue, have a look at this EndeavourOS article:

Repair a non-booting GRUB

Oh, and welcome to the community @Bussiereg

[Bussiereg]

Thanks for support, I used the linked “Repair a non-booting Grub”, I used the live USB, I used sudo arch-chroot, on my partition. I used the ```
grub-mkconfig -o /boot/grub/grub.cfg

But again when I reboot I see:
error: ../../grub-core/fs//btrfs.c:303:not a Btrfs file system
error: ../../grub-core/kern/fs.c:123: unknown filesystem

if I got to Grub rescue, when I need to do: lnsmod normal, I get the same error

[Bink]

@Bink

as well as secure-boot and fast-boot enabled

I just noticed I made a typo here

That should have read:

as well as secure-boot and fast-boot disabled

[Bussiereg]

secure - fast boot disabled, otherwise it gives me an error

[Bink]

Did it look like the grub-mkconfig -o /boot/grub/grub.cfg was successful?

@Bussiereg

But again when I reboot I see:
error: ../../grub-core/fs//btrfs.c:303:not a Btrfs file system
error: ../../grub-core/kern/fs.c:123: unknown filesystem

Where my experience ends, is at dual-booting Windows. I’m not sure if this is an issue specific to that. Hopefully someone experienced in that area can step in and provide some advice.

[thefrog]

may also need to check the bios to make sure that its not on CSM/Legacy if your using UEFI.

[Bussiereg]

I checked that, as weird as it sounds, I couldn’t find where I could switch to legacy. my computer is about 18 months old. But if it was the case I could not start windows

@Bussiereg

5 659GB 1020GB 361GB ext4 endeavouros

Your EOS partition is EXT4.

@Bussiereg

error: ../../grub-core/fs//btrfs.c:303:not a Btrfs file system
error: ../../grub-core/kern/fs.c:123: unknown filesystem

The Grub seems to be looking for a Btrfs filesystem. That is perhaps why it gives error.

@Bussiereg

Boot0000* openSUSE HD(1,GPT,0aa51a8e-e134-48cb-90a7-df70957aba59,0x800,0x82000)/\EFI\opensuse\grubx64.efiRC

@Bussiereg

please note that on the boot, the partition shows as “opensuse” but it’s EOS.

I don’t think so. I think this is the rest from when you had openSUSE installed on Btrfs.

[Bussiereg]

This is my understanding as well. now, how can I fix it? Because I do not see Btrfs partition.
So either there is one, and I should somehow instruct Grub how to use it.
Or there are none, and I should fix Grub not to believe there is one

[cactux]

@Bussiereg

Because I do not see Btrfs partition

I don’t either.

@Bussiereg

Or there are none, and I should fix Grub

Yes.

[manuel]

Check the UUID values in /etc/fstab and /boot/grub/grub.cfg.
See also if the UUIDs match the output of
lsblk -fm

[ricklinux]

I think you need to properly arch chroot and reinstall grub and run the update grub command. It seems you weren’t sure on that process. EndeavourOS is installed default with systemd-boot so did you choose grub as the boot loader when you installed? I am running btrfs and i don’t see that you have btrfs. If you are using grub then the arch-chroot procees is simple. You boot on the live ISO.

sudo mount /dev/nvme0n1p5 /mnt
sudo mount /dev/nvme0n1p1 /mnt/boot/efi

sudo mount arch-chroot /mnt

Then reinstall grub

sudo grub-install
sudo grub-mkconfig -o /boot/grub/grub.cfg

Then reboot but you may need to select and set the proper boot order. You need to check also what @manuel has said first.

[Bussiereg]

I will double check the comment from @manuel, but I did do what you are telling me to do before coming here and got the same result (going into grub rescue). Now I am not sure at systemd-boot since I replace the opensuse partition and kept the EFI partition at the same place. Maybe I should go a delete some stuff on that partition since I believe it’s shared with Win. I read I should had created a linux EFI partition.

Or maybe I should create a new linux EFI partition?

OK chroot according to the post from ricklinux higher up.

Then do this;

rm -rf /boot/efi/EFI/opensuse

efibootmgr -b 0000 -B

mv /boot/grub /boot/grub.bak

mv /etc/grub.d /etc/grub.d.bak

cp /etc/default/grub /etc/default/grub.bak

pacman -S grub

grub-install --efi-directory=/boot/efi --bootloader-id=endeavouros
