I am using Fedora 17 since a few months, already have some experience with linux OS for several years.
In Grub2 I have seen there are only two entries in the main menu by default.
Someone gave me the hint to remove the submenu entry in /boot/grub2/grub.cfg
But: If I e.g. want to update the configuration with this command:
grub2-mkconfig -o /boot/grub2/grub.cfg
the submenu appears again.
How can I edit the config files - and which config file is it - to have all menu entries on one level for selection - that it is correctly recognized by the grub config functionality?
