Grub 2:2.06.r322.gd9b4638c5-1 won't boot and goes straight to the BIOS after update

Okay I feel totally stupid here…

sudo fdisk -l

[liveuser@eos-2022.08.05 ~]$ sudo efibootmgr
EFI variables are not supported on this system.

[liveuser@eos-2022.08.05 ~]$ sudo mount /dev/nvme0n1p4 /mnt/boot

[liveuser@eos-2022.08.05 ~]$ ls /mnt/boot
EFI

[liveuser@eos-2022.08.05 EFI]$ ls
boot  EndeavourOS  EndeavourOS-grub

I am pretty sure it should be an EFI System, but yeah when I tried the Grub Repair as described for EFI Systems, this is what happened, it told me at this step it wouldn’t be an EFI System… Can anyone point me on how to fix it?

I’m completely crushed with this damn Grub Update…

You need to boot the ISO in uefi mode. Some motherboards allow you to boot it in both legacy or UEFI modes.

591

How can I force to do that? When Booting I only get to select the USB Stick, or USB Stick Partition 1.

592

It depends on your hardware.

You might try mounting /dev/nvme0n1p4 and checking to see if it is an EFI partition. If it isn’t you are probably using BIOS/legacy boot.

593

Bios shows me definitly UEFi as first boot option.
And I found a setting to boot the Stick into UEFI seperately. Must have missed that.

I think I got it now. Thank you. At least the Commands worked this time now to reinstall Grub, without showing an Error. Now I’m off rebooting and hoping for the best.

I have verified that the root partition is sda8, however when I run sudo mount /dev/sda1 /mnt/boot/efi I get this error:

I ran the sudo mount /dev/sda8 /mnt, but the error still occurs.

595

What does ls /mnt/boot show?

596

Strange…

597

How about ls /mnt

598

There’s my user folder where all the stuff lies.

It looks like your /home is mounted there. Not your /

600

Create the folders that are missing, before mounting:
sudo mkdir /mnt/boot && mkdir /mnt/boot/efi

601

Then I suppose I have to mount the sda6?

602

No, that is a terrible idea. If the directories are missing, that means the wrong thing is mounted at /mnt.

Yes, most likely.

604

Here’s the ls /mint of sda6:

605

That is the correct one. Now retry mounting /mnt/boot/efi

607

Looks like I got it:
