[SOLVED] Add "system setup" option to GRUB

Stargarth · 2020-03-26 20:43:23

Hi fellow archers!

Back in the old days, when I was using Ubuntu GRUB had this nice option "system setup". It reboots the machine and gets you to UEFI bios.

When I reinstalled my system with arch, my grub doesn't have this option anymore.
Do you guys know how to set my GRUB so I have this option again?
It looks something like this: https://i.stack.imgur.com/6UTmy.jpg

^ Put that in /etc/grub.d/ and run grub-mkconfig(8).

Or just use this if you make your own grub.cfg:

menuentry 'System setup' {
   fwsetup
}

Hi Head, thanks for the reply!

I took following steps:
1. I took your script from github and I've put it into /etc/grub.d/ . I gave it exactly the same name "30_uefi-firmware"
2. I made "30_uefi-firmware" executable via chmod +x
3. I've run "sudo grub-mkconfig -o /boot/grub/grub.cfg". Before that I backed up and removed my old grub.cfg

Unfortunately that didn't work. I don't have that additional "system setup" entry. It just stopped detecting my dual boot windows installation (I backed up my old config so np).

----------------------------------UPDATE----------------------------------

I just added this to the end of my grub.cfg file:

menuentry 'System setup' {
   fwsetup
}

I guess it's a sub-optimal solution, since this code will disappear when I will generate new grub.cfg. However, this is good enough for me, so case closed.

I post my grub.cfg just in case somebody else would have any problems:

Oh dear, that is disappointing. I just ripped the file from Ubuntu's grub-common package, didn't test it at all (I write my own grub.cfg).

Remove /etc/grub.d/30_uefi-firmware, regenerate your grub.cfg to get back your Windows entry and then add my posted three line stanza to /boot/grub/custom.cfg — I've tested that on my machine and it works.

Hah, I did exactly that just before your reply . I've updated my previous post just in case if somebody else would have the same problem.
Thanks for the help!

Use /boot/grub/custom.cfg instead, that file is sourced by /etc/grub.d/41_custom and so will survive future updates.

Stargarth · 2020-03-26 22:44:38

uhhh I think I messed up. I renamed grub.cfg to custom.cfg and I rebooted the system. It now boots into grub console. Could you please help me to solve that Head_on_a_Stick ;/ ?

No, I meant that you should add custom.cfg as well as grub.cfg rather than instead of.

You'll have to restore grub.cfg, either from your backup or by (arch-)chrooting in from a live ISO and using grub-mkconfig.

EDIT: or boot your system from the GRUB prompt then use grub-mkconfig.

I haven't used grub in years, but can't you just load the config file at the prompt?

Stargarth · 2020-03-26 23:06:09

Sorry for trouble guys! I managed to recover from live ISO. I mounted my partitions, found unfortunate "custom.cfg" and renamed it back to grub.cfg.
Oh well, maybe those posts will save somebody else from doing that :-) .
