Let's sort out the symptoms first. First openSUSE 42.1 usb boot: 1. 'Failed to set MokListRT: not found' showed. 2. "Welcome to Grub" showed. 3. "relocation 0x0 is not implemented yet" showed. 4. Pressed a key and the system rebooted. Second openSUSE 42.1 usb boot: 1. 'Failed to set MokListRT: not found' showed. 2. "Welcome to Grub" showed. 3. The system hanged. Is this correct?
