   Thanks, but . . .   
   I tried it the first time.  It told me it needed to install a new   
   package - which it did - but then told me I had no valid EFI partition.   
   YaST Partitioner did not want to let me create a new partition (of any   
   kind) in the unassigned area of the SSD.   
   Booting a current Gparted, it allowed me to create such a partition.   
   Booting back into openSUSE 15.1, YaST Partitioner allowed me to set the   
   partition type to EF and format the beast.   
   Trying YaST Boot, once again it told me I had no valid EFI partition.   
   Reboot (some changes to the partition table used to require a reboot)   
   and trying YaST Boot, once again it told me I had no valid EFI partition.   
   My new EFI partition is correctly formatted, but empty.
