Carlos, you're right, I didn't say that before. I didn't realize that it was an issue, or I could have mentioned it. Anyways, thanks for providing your input to help me out.
But more precisely I didn't mention it because the two opensuse systems aren't on the same disk, they are on the same computer.
Ok, then that's another important thing to know about, it changes things again :-) Another question: is your machine UEFI or BIOS?
Opensuse 15.0 is on /dev/sda, and I installed Opensuse 15.1 on /dev/sdb. That caused the problem I was trying to solicit help on the mail list to resolve. Opensuse 15.1 designated /dev/sdb as the default place to store the mbr, and I couldn't find a way to change that during installation to /dev/sda.
I would have to try an install to see, but what you were attempting would break the 15.0 boot.
What was an issue for me here was that I couldn't write the 15.1 boot to the mbr on /dev/sda when I was installing the 15.1 operating system on the dev/sdb disk. I still don't know how to accomplish that, other than the way I found around the problem. Kind of a lucky guess that got me out of the difficulty. Maybe the warnings from the installation software that the system wouldn't boot if I selected /dev/sda as the boot partition were wrong and I should have disregarded them. If there was only one hard drive, there wouldn't have been any issue.
The /correct/ way to install is what yast suggested, Grub on MBR of /dev/sdb (by the way, that YaST suggests this, is what makes me think it is not UEFI system). As I mentioned on another post: Generic boot code on MBR of /dev/sdb Grub on "/" partition (or separate /boot if it exists). Mark "/" as bootable in partition table. or Grub on MBR of /dev/sdb Then, two procedures. Change boot order in BIOS: sdb must boot first. or Boot sda and make grub to probe for other systems. Note that this must be repeated if second system updates the kernel. Third procedure: Edit "/boot/grub2/custom.cfg" to add an entry to the second grub. If you are interested in this one, I'll post details. -- Cheers / Saludos, Carlos E. R.
