In my GRUB (GRUB 0.97) menu the selector became invisible (changed of inversion color). I would like get my selector bar back and by the way customize a bit grub menu to be more fancy with colors. Where i could change the default b&w schema? Do i need add directives in
/etc/grub.conf ? or rather use some tool to change grub menu appearance? In fedora repo i found grub-customizer-3.0.4 but i use centos and it seems the only way is to change grub files manually.
You should be able to just install using yum install grub-customizer.
If not try this Grub customizer for CentOS
