I run my VM Rocky Linuxes with UEFI and Secure Boot enabled.
I use versions 9.4 and now testing with 9.5.
I have noticed that GRUB2 menu is showing wierd borders with ? symbols. It seems maybe its missing its fonts?
Is there any way to fix this?
Other stuff i would like to use graphical GRUB2 with custom background image, etc. But i think this is also not working if Secure Boot is enabled. When i try to modify /etc/default/grub and running grub2-mkconfig i dont see anything changes when rebooting.
It there any help how this is done with Rocky Linux 9.x?
