I'm currently preparing to fedup an F18 system to F19, looking at these instructions:
http://docs.fedoraproject.org/en-US/Fedora/19/html/Installation_Guide/ch18s0...
The bit about updating the GRUB bootloader has got gotten me confused. My system is a newish x86_64 laptop, with F18 as the only thing on it, installed from scratch (no upgrades etc).
The instructions say to look in /var/log/anaconda/anaconda.program.log where you'll find a command similar to
efibootmgr -c -w -L Fedora -d /dev/sdX -p Y -l \EFI\redhat\grub.efi
then later on, run
efibootmgr -c -w -L Fedora -d /dev/sdX -p Y -l '\EFI\fedora\grubx64.efi' -b bootnumber
Now, the command I see in the anaconda log is in fact:
efibootmgr -c -w -L Fedora -d /dev/sda -p 1 -l \EFI\fedora\shim.efi
This differs from the example in the docs by '-p 1' verses '-p Y' and 'shim.efi' verses 'grub.efi'.
So, what values should I give for the -p and -l options?
Also, its not entirely clear what 'bootnumber' value for the -b arg should be; should this the same number as used to delete the old boot entry in the previous step?
No feedback so far. Anyone?
The Y in the instructions, I think, is intended to be a variable because it can differ. what you want is the one with 1. However, running this command in shell compared to from anaconda, \E is still an E so you actually need to use two backslashes.
efibootmgr -c -w -L Fedora -d /dev/sda -p 1 -l \EFI\fedora\shim.efi
To confirm you can use
efibootmgr -v
