8 Questions that may sound strange ...
9 What version of Windows does your motherboard support?
10 Do you use any add on ( PCI / PCIe ) cards that do not support UEFI and
11 load a BIOS?
12 Have you configured a specific type of video card in the kernel?
13 .
14 The reasons why I ask this :
15 The UEFI driver for video changes type & version between Win 7 & Win 8.
16 An LSI 9211-4i ( Raid Controller / SAS  ) loads only a BIOS ... and
17 interferes with the Win 8 UEFI Video driver.
18 ( It interferes enough with the Win 8 UEFI Video driver, that Win 7 will
19 work with it. )
20 It also means no console video until init is ( almost ) completed.
21 That is when the chosen specific video card frame buffer takes over.
