How to modify grub menu

On the grub menu I would like to center the lines like the Arcolinux grub and change the background. You can help me?

Very likely to do with the GRUB theme, .

General hint: many answers lies on the Arch wiki.


i’m a little lost :hear_no_evil:
for center grub menu i must modify /etc/default/grub or /boot/grub/grub.cfg ??

Only /etc/default/grub and then

Re-generate grub.cfg to apply the changes. If configuring the theme was successful, you will see Found theme: /usr/share/grub/themes/starfield/theme.txt in the terminal.


First I modify grub to center these 3 lines and then I have to do “sudo update grub” i suppose??
But where can I find the information to center the menu?

I don’t know.

Maybe look how it is done in Arcolinux.
