+I have not seen this issue before and not seen a 2016 machine, Let's try resetting the PRAM first.
Here's how to reset your PRAM:
Shut down your machine. Yes, all the way down, not sleep or logging out.
Press the power button and then press command-option-p-r. ...
Hold those keys down until your Mac reboots again and you here the startup chime.
Let go of the keys and let your Mac reboot normally.
+That failing, try holding down the Option key on boot and go to the repair partition an run Disk Utilities.
+Do you have an external Boot disk?
