April 11, 2025

I have tried many times, the grub just not works properly, the easy way: use : Grub customizer:

install:

sudo apt update

sudo add-apt-repository ppa:danielrichter2007/grub-customizer

sudo apt update

sudo apt install grub-customizer

once installed, launch it from start menu by typing: grub customizer
