Here is what i done to get my system going again updated the bios to 2704 it was a great help. did the usual bios setting boot os other xhci auto graphics to pcie vtd disable xmp profile q boot device to usb. Now off to fix the video resoltution and hdmi audio.
Ok I Got it in stock form this Mobo with on board Intel Chip is not bootable but if you add a compatible video card then the installer works like a charm so here are the bios settings I used to get this going xHCI Auto eHCI enabled Fboot disabled SecureBoot other OS Vt-d disabled thanks
For some reason i am having issues with video resolution as when booting with unibeast the video is compressed to the top corner of screen . My video card is intel 4000 as opposed to 6870 in your case. thanks
It is a display thing and we know it has to be set to 1080P but the issue at hand is that this is happening with Installer USB before we can even install or use MB options any other ideas pointers ? thanks.
