Can't find manjaro in grub

Support
1

I dual boot Manjaro and Windows 11. Today I update some packages through yay -Syyu and reboot, and then Manjaro is no longer listed in grub. At first there’s a Windows Boot Manager (along with UEFI Fireware Setting) in it, but after I try to follow the instruction in the Manjaro Wiki, only UEFI Fireware Settings left. What should I do? What imformation should I offer? Sorry for the poor English.

Then boot the Manjaro USB stick and chroot into the system (manjaro-chroot -a) and then
update-grub on console and check, if Manjaro is detected.

manjaro-chroot -a and then update-grub on console

[manjaro@manjaro ~]$ manjaro-chroot -a

post also output from:

and in bios check:
is fast boot disabled - you may not have this option
is secure boot disabled
and in windows is fast startup disabled

Is this outopput from the chroot environment?

10

yes, it is from the chroot environment.

11

Is there any specific reason you have kernel 4.19 still installed?

12

fast startup turned off

13

idk, maybe it just stays there.

14

Try removing it, it you’re not using it specifically. From the chroot environment, run:

mhwd-kernel --remove linux419

And just for good measure, let’s install 5.10:

mhwd-kernel --install linux510

And let’s reinstall 5.15:

mhwd-kernel --remove linux515

Followed by:

mhwd-kernel --install linux515

Then try recovering grub again:

Reinstalling grub from chroot environment.

Once in the live environment, you have to reinstall GRUB. To do so, run the following:

update-grub

When successfully completed, exit the chroot environment:

exit

Followed by rebooting and seeing if it worked.

If it did, feel free to heap on the praise. If, however, it didn’t, well, then I’m not here. (Mostly, I suspect, I’ll have to be off then.)

15 
[manjaro /]# mhwd-kernel --remove linux515
Error: You can't remove your current kernel.

Should I skip this part?

16

this is not default … did you somehow modified grub?

17

I changed the theme once.

18

Yes, I think so.

Seems like nothing changed after rebooting.

See, in the archived forum:

Edit:

This: :point_down:

Seems to be some kind of RAID error. With those I’m afraid I can’t help, but please see:

21

This error only occurs once in every time I enter the chroot environment and update-grub. If I run update-grub again, it doesn’t occur.
