Hi all,
I’ve created a simple theme based on the Framework boot logo, positioning it in the same location as the boot and startup screens.
You can download the ZIP containing the theme from here:
https://download.awayfromhome.nl/framework_black.zip
Place the theme in the correct theme folder of your Grub configuration. Probably in: /boot/grub/themes/.
Add the following line to the /etc/default/grub file:
GRUB_THEME="/boot/grub/themes/framework_black/theme.txt"
and run update-grub as root.
edit: updated the text, based on the reply from @ATi
