Unable to boot into Manjaro or reinstall Grub after UEFI update in dual-boot setup with Windows

[abhat060]

Let me quickly explain the output to efibootmgr.

I have had Fedora and Ubuntu installed on this machine at various points in the past. Those installations are no longer on the system though their boot entries were not overwritten. I can access Grub when I click on fedora, but not sure if that’s booting from the EFI partition or somewhere else.

Hi @abhat060
Here is a trick that is maybe not preferred … but super easy.

OK so if grub is no longer loading we can probably fix this right from in windoze …

• Run CMD as Administrator
• bcdedit /set {bootmgr} path \EFI\manjaro\grubx64.efi
• Reboot

(of course note there is some possibility of it being a different path … but unless you did that on purpose the above should be the correct location and syntax)

[abhat060]

Thanks @cscs, I gave that a shot, but no luck

[cscs]

Sorry then.
These will undo that set and optionally set the winbootmngr again:

bcdedit /deletevalue {bootmgr} path \EFI\manjaro\grubx64.efi

bcdedit /set {bootmgr} path \EFI\Microsoft\Boot\bootmgfw.efi

[abhat060]

Thank you, but it actually didn’t change anything.

One thing I noticed by booting into Manjaro live env is that the actual path is
\EFI\Manjaro\grubx64.efi
the only difference being the capital ‘M’. I retried with that but still no luck/change.

Any other ideas?

Not sure this is relevant but your efibootmgr -v shows a lot of entries while your efi partition is with 100MB quite small, maybe do a clean out.
Also, always use the latest manjaro iso to boot.

The following thread has a further tips on a similar issue: GRUB INSTALL ERROR: Unknown filesystem - #63 by winnie

[abhat060]

Thanks for the link, yes I tried following that thread, looks like the OP had to do a reinstall.

Re: 100MB, I have variously seen suggestions that the efi partition should be 300MB or 512MB. In fact the manjaro installer also calls it out, but it did not a few years ago when I did my original installation.

In front the 100MB partition currently sits Windows. One option is to move Windows forward by a few 100megs and then shrink its partition, but that sounds like a good way of killing Windows. I’ve had plent of bad experiences with attempting to move or even defrag Win, so not leaning in that direction.

[6x12]

No, I didn’t mean resizing it, just delete obsolete entries:
sudo efibootmgr -b <obsolete-entry> -B

Use Linux efibootmgr Command to Manage UEFI Boot Menu - LinuxBabe

Since this was caused by an update, what kernel are you on? Maybe show us an inxi -Fz

[koshikas]

here is my take on this;

• boot into manjaro-live.
• go into your existing manjaro partition.
• get partiton details “lsblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME”
• make sure that /etc/fstab refers to correct UUIDs for EFI and system and other partitons now
• ONLY AFTER use “manjaro-chroot -a” (i frankly see no reason why ppl mount invidual partiton anymore)
• choose the appropriates systems in chroot prompt is you get one
• remove unnecessary bootloaders with " sudo efibootmgr -b {bl-index} -B"
• then use “grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck --no-rs-codes --verbose” (bootloader-id is the exact directory the boolader will be created in the EFI partition)
• check if the boot loader has enlisted with “efibootmgr -v”
• if so “sudo update-grub”
• “sudo efivars -l” might not work unless you logout and chroot in again

notes:

• alternatively to “grub-install”, if it doesnt work, you may use (where --disk is the disk and --part partition number of EFI partiton);
  efibootmgr --create --disk /dev/nvme0n1p --part 1 --loader “\EFI\manjaro\grubx64.efi” --label “manjaro” --verbose

• 100MB is plenty enough for Windows + 1 linux distro-bootloader

• stick to efibootmgr for bootloader manipulation

[abhat060]

Hmm, so I can execute on efibootmgr -b -B, but does that have any benefit at this moment in time other than just giving me a cleaner menu?

@koshikas I followed your steps (with the exception of removing old boot entries), and this is what I get after grub-install

After this I see manjaro from efibootmgr -v
Boot0005* manjaro HD(1,GPT,187cd5f4-1d56-4e19-bb9f-63b345ddf421,0x800,0x32000)/File(\EFI\manjaro\grubx64.efi)

This now lands me in a grub rescue console now. I can still boot into Windows by manipulating the boot order from the BIOS, but not sure if this is a step in the right direction.

Any further thoughts?

Thank you for all the help everyone!

Something really interesting just happened.

I did execute a bunch of

efibootmgr -b 0002 -B
commands, and each time I did, that entry was removed. At the end of it, when I ran efibootmgr -v, that entry would be gone.

Then I reboot my system without the live USB and went into Windows. I came back to the live USB after a reboot, entered chroot, and again typed in efibootmgr -v. Two of the entries that were previously deleted are back, but what was previously Boot0003 is now gone.

[root@manjaro-gnome /]# efibootmgr -v
BootCurrent: 0003

Boot2001* EFI USB Device	RC
Boot2002* EFI DVD/CDROM	RC
Boot2003* EFI Network	RC

Why would Boot0001 and Boot0002 come back after a reboot?

did you run “update-grub” after (that is after “efibootmgr --create…” command"), which restores grub entries. windows grub entry could be manually put or you can go the lazy way by enabling os-prober.

happens, there are different EFI systems from different vendors. though on a different EFI camp, this has happenned to me before as well.

you can manualy check which bootloaders are installed when you chroot (assuming your fstab entries/UUIDs are correct). assuming the EFI partion is mounted on “/boot/efi” the list would be “ls -l /boot/efi/EFI” (note: this for listing only, do not manipulate in any way)

I re ran efibootmgr --create and then an update-grub. Here is the output

[root@manjaro-gnome /]# efibootmgr --create --disk /dev/nvme0n1p1 --part 1 --loader "\EFI\manjaro\grubx64.efi" --label "manjaro" --verbose

The last entry is newly added.

Then this was the output of update-grub

It doesn’t seem to make a difference

For what it’s worth, in manjaro-chroot, /boot/efi/EFI/Manjaro* does not exist after update-grub, not sure if that’s a problem.

should be listed as “/boot/efi/EFI/manjaro” since you created the label “manjaro”.

@abhat060

It doesn’t seem to make a difference

run previous grub-install comand as well
ignore “grub-probe: error”, it’s because of the chroot environment. just reboot normally to see if it works

[abhat060]

Okay, so here’s what I did now:

1. Got into Manjaro live env
2. In terminal, went into su
3. ran manjaro-chroot -a
4. did cat \etc\fstab and ensured that UUIDs were what I wanted when compared to output of parted -l
5. ran grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck --no-rs-codes --verbose
6. Step 5 gave me the same error so I ensured that no manjaro was not present in efibootmgr -v
7. Ran efibootmgr --create --disk /dev/nvme0n1p --part 1 --loader “\EFI\manjaro\grubx64.efi” --label “manjaro” --verbose
8. Ran update-grub
9. Ensured that manjaro was present in efibootmgr -v
10. Rebooted

No luck. I am being dropped into Grub rescue again.

@abhat060

/dev/nvme0n1

oops wrong device, should be;

/dev/nvme0n1

efibootmgr --create --disk /dev/nvme0n1 --part 1 --loader “\EFI\manjaro\grubx64.efi” --label “manjaro” --verbose

@abhat060

Installing for x86_64-efi platform.
grub-install: info: cannot open `/boot/grub/device.map': No such file or directory.

sudo grub-mkdevicemap
sudo update-grub

[abhat060]

Hmm, unfortunately grub-mkdevicemap is returning as

bash: grub-mkdevicemap: command not found

I can’t find that package on pacman either or AUR. Is there an equivalent command that I can use for Manjaro or find that package somewhere else?

[abhat060]

Ah, that makes sense, I had been using /dev/nvme0n1p.

Now I executed with /dev/nvme0n1.

No luck

I wonder what’s going on with the /dev/nvme0n1p1, it’s like no changes are persisting.

[koshikas]

so few more things, apparently why grub-install works on some systems but not on others to install both grub and EFI entry is because the live-media is not in EFI mode. you cant test which mode your live-media is on by

test -d /sys/firmware/efi && echo efi || echo bios

i use ventoy created in EFI mode (create with -g switch). this is not mandatory but will make things easier as i have found.

you are here now;
https://wiki.archlinux.org/title/GRUB#Drop_to_rescue_shell

check whehter you got /boot/grub/grub.cfg
if not;

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

and also for nvme drives you can directly use “efibootmgr --create --disk /dev/nvme0n1p1 …”
