Fixed by adding additional UEFI boot entry: ``` # efibootmgr -c -d /dev/md126 -p 1 -L "OpenSuse" -l '\EFI\opensuse\grubx64.efi' ``` ``` # efibootmgr -v | grep suse Boot0000* OpenSuse HD(1,GPT,d06bc6d5-def1-41fc-a993-9197551c7be7,0x800,0x82000)/File(\EFI\opensuse\grubx64.efi) ``` ps: I suggest you automate it as figuring it out takes a lot of time. pps: Opensuse Tumbleweed is awesome, thanks for all your hard work! <3
