This should work on any Linux distribution that uses GRUB, but I have only tested it on EndeavourOS and Kali
git clone https://github.com/AllJavi/tartarus-grub.git
cd tartarus-grub
sudo cp tartarus -r /usr/share/grub/themes/
sudo vim /etc/default/grubChange #GRUB_THEME= to
GRUB_THEME="/usr/share/grub/themes/tartarus/theme.txt"
sudo grub-mkconfig -o /boot/grub/grub.cfgIf all works correctly you should get this line in the out put:
Found theme: /usr/share/grub/themes/tartarus/theme.txtWhen editing the file /etc/default/grub, you also have to comment the line 'GRUB_TERMINAL_OUTPUT="console"
