Thread: OS13.1 Kernel update killed UEFI boot and how I recovered

    Lightbulb OS13.1 Kernel update killed UEFI boot and how I recovered

    Hi all,
    I run OS13.1 with Kernel 3.12 on a UEFI machine. Everything ran find until yesterdays kernel update. After that one no operating was found for booting.

    I had to spend a couple of hours to figure out how to recreate the UEFI boot menu entry. In the end my solution is a mixture of many ingredients from different sources:

    1) Start a recovery system in UEFI mode, e.g. from your opensuse install medium.
    2) mount /dev/sda3 /mnt (my root system is on /dev/sda3 yours might be somewhere else)
    3) mount --bind /dev /mnt/dev
    4) chroot /mnt
    5) mount -t proc proc /proc
    6) mount -t sysfs sysfs /sys
    7) mount /boot/efi
    8) efibootmgr -c -d /dev/sda -p 1 -L opensuse -l '\EFI\opensuse\grubx64.efi'
    9) reboot

    For me that worked. I hope it helps others, too.

    Cheers
    Frank

    You could spare most of the steps - there was no need to chroot efibootmgr is not interested in actual filesystem content - it trusts you to provide correct paths.

    O.k. So you mean that this would have worked two:
    1) Start a recovery system in UEFI mode, e.g. from your opensuse install medium.
    2) efibootmgr -c -d /dev/sda -p 1 -L opensuse -l '\EFI\opensuse\grubx64.efi'
    3) reboot

    I haven't tried this and I hope I do not have to

    Cheers
