Do I need GRUB2-EFI

Hi,

The FedUp documentation 'http//fedoraproject.org/wiki/FedUp' confuse me a bit. First they say 5. ..., the system will reboot and an option Fedora 19 will be on the grub menu. But a few lines later, under Updating GRUB2 (BIOS Systems), they tell After upgrade, the grub2 you're booting from will still be the F17 version; upgrading must be done manually. And to make it even more confusing While updating GRUB on your upgraded system isn't strictly required, it is recommended for BIOS systems ...

My question: when is a GRUB2-EFI updating recommended and why (I like to know what I'm doing)?

Also a link to a good GRUB2-EFI tutorial is welcome.

Thanks in advance,

kdg1955

My question: when is a GRUB2-EFI updating recommended and why (I like to know what I'm doing)? I use a ASUS Z87-K motherbord that have a EFI BIOS. But UEFI drivers are not installed.

Also a link to a good GRUB2-EFI tutorial is welcome. I only find this link: 'http //fedoraproject.org/wiki/Grub2', but here also is not made clear whether you better install GRUB2-EFI or not. Google search gives little or no information about the differences between GRUB2-EFI and GRUB2.

Thanks in advance,

Comment after upgrade to F18:

Am I so stupid now? I have just done an upgrade to F18 and then wanted to install grub2-efi. But the manual was not very helpful.

  1. /boot/efi/EFI/fedora/grub.conf wasn't present after installing grub2-efi.
  2. efibootmgr wasn't installed. You need to install it also with sudo yum install efibootmgr.
  3. I can't find the argument rd.luks.uuid in my old configuration file of GRUB2 /boot/grub2/grub.cfg.

What is going wrong, where is the key to achieve a better understanding of the grub2 / grub2-efi issues? As mention earlier I do not have much understanding of the EFI matter.
