    Question Howto Update Grub on EFI system? [SOLVED]

    I'm running F21 Beta RC1. I have a problem getting changes to the grub configuration to implement on a UEFI system. I'd appreciate any help, because I'm no UEFI expert.

    Here's what I've done:

    I've edited /etc/default/grub to contain the following values:

    GRUB_TIMEOUT=30
    #GRUB_CMDLINE_LINUX="rhgb quiet"

    then I tried rebuilding grub using the traditional "bios" method, which doesn't work on an efi-type system.

    Code:
    grub2-mkconfig -o /boot/grub2/grub.cfg
    what changes do I need to implement for an efi-type system?

    tia.
