   Hi. 
I've fixed memory issues with my MB now I ca't install windows.
http://forum.asrock.com/forum_posts.asp?TID=9248&PID=54040&#54040

I've disabled IOMMU option as FAQ says. I've able to boot windows installer from USB.
But after it windows says it is not enough drivers and asks to look for them.
Looks like it can't see storage devices. I've have Samsung 850 1Tb evo sata ssd, and 4*6Tb Seagate IronWolf hdd. Everything is configured in AHCI mode, no raid. 

I've tried to give installer any driver I've found on asrock but now effect. How could I install windows 10?

	update: 1. UEFI sees devices correctly. 2. Ubuntu could install itself from 1st try. Problem obviously in windows drivers, most probably AHCI drivers not the hdd/ssd, because i've couldn't see nor ssd nor hdd.

	Solved. I've created windows boot USB just copying iso to usb with mac dd utility, this is incorrect way. This installation couldn't be installed on new hardware because Rufus or Windows Install Creation utility download and put additional drivers during installation USB/CD creation, which wasn't done in my case. I used Rufus and everything became ok, you need just have some other working windows to do it
