My system is
Asus Z170-P Motherboard
i5 6600K Processor
NVIDIA GeForce GTX 1050 Ti 4095 MB
Be-quiet 500W PSU
Crucial 16 GB 2400 MHz DDR4
xHCI Handoff enable
Serial Port disable
SATA AHCI mode
IOAPIC 24-119 Entries (enable y disable) two mode stuck
I can not build a robust and stable system, The system Sierra is already installed but when I restart or shut down, I get the error Still waiting for root device error, but after too many reboot ( from 2 times to 9) start correctly or other times leave too minutes, with prohibited symbol and finally starts.
Once started recognised correctly HDD.
Also I tried with a new EVO860 nvme SSD , but I have the same problem.
I dont know because sometimes yes sometimes no, the system stuck in this error
I add some information files and logs.
