You do need a manager like efibootmgr unless you have a really good "bios" menu where you can manage your entries. Only removable media is autodetected on all EFI boxes I've seen. I use GRUB2 because my efi firmware (like most) is really buggy. Changing the boot order doesn't work at all (neither on the menu nor through efibootmgr), so I have to delete and recreate the entries in the right order. What I did is create 2 efi entries, one for my main kernel and one for grub2 and I added entries for all my secondary kernels and windows on the grub2 menu. -- Fernando Rodriguez
