Before and After Install Sierra, system displayed the forbidden icon

[persistz]

i5 7500 + MSI B250M mortar, without Discrete Graphics, used HD 630
When I tried to install the Sierra with unibeast, the system sometimes displayed a forbidden icon after the apple logo, but this not displayed every times, so I can install the Sierra successfully after several reboots.
Then I finished the install process, used multicast with quick start and added realtek ALC892 drivers.

But when I reboot the computer, the forbidden icon displayed again...
How to solve the problem? or which log should I provided for you reference?
Thanks a lot if you can reply me.
