    You have check the box for "Custom Boot Partition". And then you have to enter the device (such as "/dev/sda"). Note that this will be the device names as known to the installer.

    During an install, when the summary page is showing click on "Booting" to get to the detailed settings.

    Never to my knowledge has openSUSE provided a /boot/grub/grub.conf file. With Grub Legacy it's always been /boot/grub/menu.lst, same as upstream Grub (because of the FAT 8.3 filename limitation involving Grub4DOS), and which Debian and its derivatives (including *ubuntu) used before they switched to Grub "v2" a decade ago. Grub2 for MBR booting openSUSE (or any other distro) I've never used, but since with UEFI booting it uses /boot/grub2/grub.cfg, and *ubuntu uses /boot/grub/grub.cfg, I'd expect /boot/grub2/grub.cfg to be used by Grub2 in openSUSE, and what your Ubuntu configfile line for TW would need.

    Thank you so much, I'll go for custom boot partition next time.

    Thank you but apart from configfile, the bigger issue I had was, GRUB2 being written in hd1 instead of hd0. And thanks to @nrickert, I now know, to use custom boot partition option at the beginning of installation.

    There was only one option to login with OpenID, which I even spent 5+ min on how to get one, only to find out that it's paid service.

    So I've uploaded all the screens from this thread onto OneDrive:

    Login is not needed to create a paste at paste.opensuse.org and it is the preferred way to attach stuff to an openSUSE forum post; with a login you may be able to edit or erase your paste, but this is not needed generally, just set a low expiration term if you prefer so.
