[SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Hello,

I did a fresh install of Arch Linux (dual booted with Windows 10). I can boot into Windows 10 normally at startup. When I boot into Arch GNU Grub starts instantly.

I can then boot into Arch with:

set root=(hd1,msdos3)
linux /boot/vmlinuz-linux-lts root=/dev/sdb3
initrd /boot/initramfs-linux-lts.img
boot

Once in Arch I've tried:

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

Which resulted in:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux-lts
Found initrd image: /boot/initramfs-linux-lts.img
Found fallback initrd image(s) in /boot: initramfs-linux-lts-fallback.img
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
Found fallback initrd image(s) in /boot: initramfs-linux-fallback.img
Found Windows Boot Manager on /dev/sda2@/efi/Microsoft/Boot/bootmgfw.efi
done

Which it looks like it is finding everything it needs/wants. But when I reboot, same issue.

Any advice or help is greatly appreciated.

Thank you in advanced.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Use the set command (with no arguments) from the GRUB prompt to see the configuration.

I would try re-installing GRUB to the disk, how did you do that originally?

Original install was done with (after mounting the /boot/EFI)

grub-install --target=x86_64-efi --bootloader-id=grub-uefi --recheck

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Looks good, what is the output of

efibootmgr -v

I have to go to $DAY_JOB now, I'll be afk for ~10 hours or so.

EDIT: actually, try again but explicitly specify the ESP location with the --efi-directory option.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Looks like your motherboard isn't accepting new NVRAM (boot) entries so it's still loading Ubuntu's GRUB, which doesn't work because the configuration file isn't there any more.

Try deleting Ubuntu's entry:

# efibootmgr -b 1 -B

Then use the removable loader location for Arch's GRUB:

grub-install --target=x86_64-efi --bootloader-id=grub-uefi --removable

If it doesn't work (your motherboard may just boot Windows' UEFI loader instead) then force Windows to chainload Arch instead by running this command from an Administrator prompt in Powershell:

bcdedit /set "{bootmgr}" path "\EFI\grub-uefi\grubx64.efi"

Double-check the path to grubx64.efi, it should be relative to the EFI system partition.

If that works then you will have to use the GRUB menu to start Windows.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

So I deleted the Ubuntu option on efibootmgr, check and it shows deleted. But when I reboot that option is still there in BIOS.

I rebooted into Arch via live usb to reinstall GRUB on /dev/sda2 (where my system efi partition is at). If I mount it

mount /dev/sda2 /mnt/boot/EFI

When I go to install again, using:

grub-install --target=x86_64-efi --efidirectory=/boot/EFI --bootloader-id=grub-uefi --removable

I recieved error:

grub-install: error: cannot find EFI directory

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Mount your root partition and your ESP as they would be mounted for the installation process then arch-chroot in and run grub-install from the chroot.

If you have the ESP mounted to /boot/efi then you don't need to specify --efi-directory

EDIT: if you can't delete the Ubuntu NVRAM entry then you may have to copy $ESP/EFI/grub-uefi to $ESP/EFI/ubuntu, which is a horrible hack but not as horrible as the UEFI implementation on your motherboard.

I did everything as stated and got no errors. But now it just boots directly into GNU Grub.

Edit: It still shows (ubuntu) for whatever reason even after deleting it from efibootmgr and reinstall grub via arch.

Edit 2: Just saw your edit, mind walking me through that?

The shimx64.efi loader listed in the Ubuntu NVRAM entry should auto-load grubx64.efi in the same directory.

Tried that and no luck.

I can look into the ubuntu folder and I see both the shimx64.efi and the grubx64.efi, but still boots to GNU GRUB.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

How about copying grubx64.efi to shimx64.efi? My heckles are rising as I type that but we're getting desperate here.

There's also the bcdedit command from Windows, that should chainload Arch's grubx64.efi from the bootmgfw.efi NVRAM entry.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Did you try the bcdedit command from Windows?

There is also https://wiki.archlinux.org/index.php/Un … up_in_UEFI

The NVRAM boot entries are exposed via sysfs and you could try manually deleting /sys/firmware/efi/efivars/Boot0001* (and perhaps the /sys/firmware/efi/vars/{l,}Boot0001* directories) but that carries the risk of bricking your machine.

I tried the original bcdedit command posted a few posts up. I will look into the efibootmgr link as soon as I am back at my computer (few hours).

I appreciate all the help and hopefully I come across a solution.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Making some progress. I was able to make my own boot entry by following that link. I thought I linked it to GRUB but apparently not. I can now see a GRUB boot option (which I named myself) but when I select it nothing happens. There is still Windows and Ubuntu options as well.

Re: [SOLVED] Fresh Arch Linux Install Boots to GNU Grub

Finally figured it out. My fix below, in case anyone had same issue.

First I noticed I had hanging (leftover) boot files in my EFI partition. I went ahead and deleted all directories and their contents (excluding Windows files).

From there I did a fresh install of GRUB.

mount /dev/sdb3 /mnt ***this is where my / is***
arch-chroot /mnt
mount /dev/sda2 /mnt ***This is where my EFI partition is***
grub-install --target=x86_64-efi --efi-directory=/EFI --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

From there I went into my  EFI partition to make sure everything was there.
I noticed it installed in /EFI/EFI/GRUB/grubx64.efi

Reboot.

Still didn't have a boot option from my BIOS.

arch-chroot back into /

efibootmgr --create --disk /dev/sda --part 2 --loader /EFI/EFI/GRUB/grubx64.efi --label "GRUB" --verbose -e 3

Tuh dah!

Good to go. Boots normally. From there I just had to make GRUB my primary boot.
