No OS Found

I'm having trouble installing Factory on my E325 ThinkPad Edge. Accepting the defaults, turn off secure boot (my laptop does not support secure boot.) GPT & EFI. After install the laptop reboots to no OS found. I'm thinking after Googling my Lenovo possibly has non standard EFI as per Ubuntu forums, however nothing SUSE specific. The installer chooses GRUB2-EFI automatically the only other options being GRUB2. When I installed 12.3 I had to switch on legacy boot in order to install. This seems to be the same problem.

EDIT: If I go with all defaults, secure boot check box ticked, the bootloader config fails to install. I then uncheck secure boot check box & laptop actually reboots to Factory. OS found! However new bug;

"Calling YaST module `inst_automatic_configuration has failed" All my username/password settings are not present to log in & it prompts to enter new user settings.

I reboot, problem solved!

Boy! Hairy!
