I think I deleted my themes in grub

Hello I think I deleted my theme! I try to update my grub with

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

Could you please let me know how to grab it back I kind of miss it!

Thanks you!

Exactly the same happened to me yesterday.
Take a look at my thread. @pebcak got the solution for me reinstalling the grub in chroot

hsdredgun · November 11, 2022, 10:08am

Thank you! But in my case I can boot without a problem I just deleted the theme… Wonder if I have to delete and reinstall the all grub

pebcak · November 11, 2022, 10:14am

What shows

cat /etc/default/grub

?

Ah,

You want the grub theme back?

Have a look here or here.

I am having the exact same issue as OP. I am also able to boot normally after pressing any key.

cat /etc/default/grub shows this:

# GRUB boot loader configuration

Few days ago someone suggested to comment out the THEME section because some EnOS package got removed from repos.

Did you run sudo grub-mkconfig -o /boot/grub/grub.cfg after that?

dalto · November 11, 2022, 3:29pm

You have to edit /etc/default/grub and then run sudo grub-mkconfig -o /boot/grub/grub.cfg

Smokus · November 11, 2022, 3:43pm

I am pretty sure that I did. Will do it again, and see if it helps.

@dalto that was the fix I guess Thanks

swh · November 11, 2022, 6:05pm

so you were lucky
i did not run

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

so i have to reinstall grub in chroot . but i surely learned from that mistake

Smokus · November 11, 2022, 8:45pm

I mean I didn’t run it few days ago, and got the error from above only today. But I was able to boot normally every time after clicking the error away.

Running sudo grub-mkconfig -o /boot/grub/grub.cfg made the error go away

hsdredgun · November 11, 2022, 8:47pm

Yes I just miss the wallpaper at the back ground and for science I want to know how to get it back haha

pebcak · November 11, 2022, 8:53pm

So it looks like you have removed the lines related to EnOS Grub theme from /etc/default/grub.

If you want to get rid of the error messages at boot, most probably

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

should help.

If you want to get the theming back:

Please click on here or here in the box above.

If you install the theming package again, You would need to add back the lines you deleted in /etc/default/gub and regenerate grub.cfg.

dalto · November 11, 2022, 9:07pm

The theme has been removed from the repos but you can easily set a wallpaper with the wallpaper with

GRUB_BACKGROUND="/usr/share/endeavouros/splash.png"

That is our standard grub wallpaper.

dalto · November 11, 2022, 9:10pm

There should be no need to chroot when changing a wallpaper or grub theme.

hsdredgun · November 11, 2022, 9:18pm

Thank guys

Uncomment one of them for the gfx desired, a image background or a gfxtheme

GRUB_BACKGROUND=“/path/to/wallpaper”
GRUB_THEME=/boot/grub/themes/EndeavourOS/theme.txt

I got it back!!! legendary no needed to get to the chroot!

swh · November 11, 2022, 9:30pm

Glad you got it back and dont need to reinstall grub with chroot. In my case i couldnt boot so i need to chroot. In the end we are all happy
