Hi everyone. I just finished my build and I'm getting the error listed in the title. I fixed all of the relevant motherboard settings for my board and I'm kind of stuck. The only settings I couldn't find were "OS Type" and "XHCI Handoff". I'm not sure if these are important. I also haven't tried a different USB port. Another possible cause could be my boot usb, it was originally formatted as MBR. I haven't switched it to GUID yet but again, I'm not sure if this is important or not. Any help would be greatly appreciated.

I'm running:

i-5 6500
750 ti SC
MSI H170i pro ac board.

Thanks

@Kineticcz, please update your profile (personal details) with your build (Motherboard, CPU and Graphics Card).

Yes it is.
