The grub2-install command above - with efi you have to "announce" the the information to boot with. I look at it as similar to grub installing into the MBR, but thats a very loose metaphor :) The problem you are describing might be that this "announcement" is missing/corrupted. The EFI directory is Apples (this is a macbook air), the grub2-mkconfig searches for all the bootable kernels and builds a menu for them. I think this is close to default efi in layout as "EFI" seems to be in the spec. BillK
