Hi,
seems I'm still very new to UEFI and currenty way of bootloading.
So I've got 13.1 and 13.2 both installed now but normal boot up shows only the 13.1 boot entry still.
uefi bios, no more grub, is responsponsible for choosing the booting system. You probably have 13.2 in the boot bios menu (key vary from system).
I guess I _could_ add the other install to EFI but it's not my preferred solution and actually I still don't understand how I'd do this (if it's really possible or intentional). As pasted before Boot0000* openSUSE HD(1,800,4e000,7e36557b-6396-4f70-9287-7d7b8e00c927)File(\EFI\opensuse\grubx64.efi) This only tells EFI to use grubx64.efi to take over, right? But where is defined what grubx64.efi actually does? That is the main open question for me.
that said, usually, grub *can* boot the other system
read this already but it's not really giving answers for detailed questions. Just some rough overview which I already understand.
Thanks, Wolfgang
Hi If your going to dual boot openSUSE, you will probably need to rename the first install, don't think openSUSE will handle it... Then use efibootmgr to add an efivar entry. You can just copy the files over into a new directory and then use the efibootmgr to create a new entry. eg mkdir -p /boot/efi/EFI/SuSE cp -ar /boot/efi/EFI/opensuse/grubx64.efi /boot/efi/EFI/SuSE/grubx64.efi efibootmgr -c -L "openSUSE 13.1" -l "\\EFI\\SuSE\\grubx64.efi" efibootmgr -v You can change the boot order, what to boot next, delete entries, re-add them. The kicker is how new the efi is. My HP ProBook 4430s (non secure boot) is a bit flakey, yet the HP ProBook 4440s's I have are much better, plus do secure boot. The efi file just calls the kernel (just like grub), I guess in a way it's the mbr in the bios with additional features... -- Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) openSUSE 13.1 (Bottle) (x86_64) GNOME 3.10.1 Kernel 3.11.10-21-desktop up 23:39, 3 users, load average: 0.38, 0.35, 0.31 CPU AMD Athlon(tm) II X4 635@2.9GHz | GPU Nvidia GeForce 8800 GT -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
