[SOLVED] Can't boot after update-grub

Hi,

I wanted to add a grub theme. So I downloaded this Theme . Then I extracted it in

/boot/grub/themes

and after that I entered the command

sudo update-grub

. I didn't had this command available so I add a file by that name in

/usr/sbin

directory and add the following code.

#!/bin/sh
set -e
exec grub-mkconfig -o /boot/grub/grub.cfg "$@"

then I gave it the permission necessary to execute the file. And it run successfully without any error. So I restart the computer to see the new theme but now It's not detecting anything. It's like it's not even aware of the existence /boot and / partition.

any way to fix it?

Edit /etc/default/grub and add:

GRUB_THEME=/boot/grub/themes/CyberEXS/theme.txt

Re: [SOLVED] Can't boot after update-grub

I don't use GRUB but according to the wiki the way to do it is to edit your custom configuration file in /etc/grub.d and regenerate it with grub-mkconfig -o /boot/grub/grub.cfg instead of update-grub.

. I didn't had this command available so I add a file by that name in

I don't think you should mess with this manually and but simply allow grub do it's work.
I would revert everything back to what it was before making sure you can actually boot and find out how to properly trigger the theme just as NancyS advised.
If you want to use themes for your bootloader, I would recommend rEFInd instead of Grub where themes are far more straightforward.

Re: [SOLVED] Can't boot after update-grub

Thank you for the reply I already had this. But I was missing quotes around the path

GRUB_THEME="/boot/grub/themes/CyberEXS/theme.txt"

Also, running

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB

seems to solve the issue
