Re: .

Do you not even get to GRUB? if you double check from the ISO with efibootmgr, does the generated entry for GRUB exist/stick? Which mainboard is this? If anything MSI, see the green tip box in https://wiki.archlinux.org/index.php/GR … allation_2

Check this post of mine: https://bbs.archlinux.org/viewtopic.php?id=259748
Maybe you should install the system into /dev/nvme0 instead of /dev/nvme0n1 ?

Also new here myself, don't have much experience, but your fdisk output is so close to the one from my Mac's diskutil the time I got the installation wrong...

@Arciere depends, if you look into /boot without having mounted the ESP I'd expect it to be empty if you mounted the ESP to /boot like you did during installation there should be files/kernels and grub config/files there. As for efibootmgr check/post the output of

efibootmgr -v

@Richardn No /dev/nvme0n1 is the correct level at which to allocate partitions that shouldn't be the issue here.

All would be best, use a pastebin for posting terminal outputs.

And please post the output of

efibootmgr -v -u

So it's easier to read.

Re: .

So, Grub is registered by the EFI as an available loader.
Please post the output of

$ lsblk -o +fstype,parttypename,uuid,ptuuid
$ mount
$ cat /etc/fstab

Re: .

Sorry, a quick info. I gave this command found on the Wiki to load the previous output:

efibootmgr -v -u |& curl -F 'f:1=<-' ix.io

But if I gives it back, I upload the new output to the exact same link (I think). What should I change in this command to change the link and thus be able to keep both outputs online?

This might be due to the ix.io server comparing the input by hashes. This way the server can prevent storing duplicate (identical) data.
So most likely the output of efibootmgr has not changed and thusly the server does not generate a new entry.

Re: .

Hm. That looks mostly good.
With the exception that the GRUB entry's UUID does not exist on your system.
I'd try to just re-install grub again.

# efibootmgr -b 0000 -B
# grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB
# grub-mkconfig -o /boot/grub/grub.cfg

Re: .

You can try a different boot manager, like systemd-boot.

Re: .

That's not going to help, it's not going to retain systemd-boot entries either. If your UEFI is indeed not retaining the entries, follow the tip box I've mentioned regardless to install it into the fallback location, that one should boot when you select to boot off of the drive.

In any case, what you also can do is go through the UEFI firmware and check whether you find an option to manually add entries to the boot menu.

Possibly. My goal was to rule out a problem with Grub, though.
Also, it's not clear to me that the EFI does actually not retain the loader entries.
In the output from the chrooted system, it's clearly there.

@Arciere:
Is the grub entry gone from

efibootmgr -v -u

after you rebootet the live system?

Re: .

@Arciere that's what I meant yes.

@schard I see the sentiment, however even if GRUB was bugged to hell and back one needs an entry in the corresponding UEFI loader. Right now the EFI doesn't show anything at all, that's currently not really related to any software that should or would potentially run, and if the EFI signature of GRUB was broken then no one would be able to use it and we'd see reports here.
