    And I found, that in YaST in GRUB settings there is an option called "Order of drives", but changes in this menu do nothing.

    Can you try with:
    Code:
    sudo grub2-install --force --disk-module=native /dev/sda2
    Your external drive shows up as "/dev/sda"?

    No, I'm trying to install the internal GRUB to boot the external OS. I haven't yet tried the nativedisk method with the external. I'll give it a try.

    I booted the openSUSE, that is on the external drive, ran
    Code:
    sudo grub2-install --disk-module=native /dev/sdb
    and it worked. I changed my boot order in my BIOS, so it tries the external hdd first. It works and that's important. Thanks a lot again for your patience.

    Glad you got it working.
    Installing to the partition /dev/sdb2 etc. makes that system unbootable from Grub.
    Although that is a good way to multiboot more than one Linux system, possibly with windows, putting grub on one system and the rest on partitions so you're not having grub jump from one install to the other every time grub is updated.

    On the system that you do want grub to control you would then install it to the drive /dev/sdb and not the partition /dev/sdb2.

    I have a Wiki about customizing grub. The above is mentioned in section 1.8 of the Wiki. It is for Debian systems mostly but I customized my Arch Linux install with it and just some minor adjustments.

    Of course you would update your grub after any changes with sudo grub2-mkconfig -o /boot/grub2/grub.cfg instead of sudo update-grub, unless you made that an alias for the other command.

    Regards
