A short recap: 

I had opensuse 13.2 installed and was able to boot to GRUB, then Windows (or
openSUSE) with SecureBoot enabled.  I upgraded to Leap 42.1 and was able to
boot to GRUB, then to openSUSE, but not Windows with SecureBoot enabled.

I then updated to the first test version and I was not able to boot to GRUB
with SecureBoot enabled.  No errors were visible, IIRC.  The system kept
rebooting.

I then updated to the second test version and I was not able to boot to GRUB
with SecureBoot enabled.  No errors are displayed.  The system kept rebooting.

With SecureBoot enabled, that is correct.  I cannot boot even to GRUB.
