First of all, I would like to inform you that this motherboard has been out of support since December, 2012.
Also, Windows 8 or 8.1 is not a supported operating system for this specific motherboard therefore; there are no plans for making drivers. http://www.intel.com/support/motherboards/desktop/sb/CS-008326.htm
As far as I remember, 4th series motherboards do not come with UEFI and this feature is require in order to install Windows 8.1.
The DQ45CB will boot in UEFI mode with x64 Windows 10, and probably in Windows 8 and 7 as well. I am running Windows 10 booted with UEFI/GPT right now as I type this reply. In addition to setting the board to use UEFI, you have to set the SATA mode in the BIOS to RAID and supply an "F6" Intel ICH10 RAID driver downloaded from Intel's website during Windows installation. I got the same errors as the OP time and time again until I came across this hint in another forum. You don't have to pre-format the drives or anything; setup will do that for you, creating four partitions on an empty (GPT) drive. Unfortunately, setting the SATA mode to AHCI and supplying an F6 Intel ICH10 AHCI driver during Windows installation does not work. You just get the same behavior as if you didn't supply the driver.
Thanks. I was trying to load Server 2012 in UEFI mode for my 4TB mirrored drives, but couldn't figure out how. I cheated by loading it from the new Dell I picked up, then moving it to the DQ45. I will have to try this the next time I have some free time. Are the RAID drivers fairly comprehensive (covers many OSes and boards)?

Microsoft® Windows Server 2012 is not compatible with Intel® desktop motherboard (Home Use); however, you can install the operating system and use generic drivers of Microsoft® Windows. The hardware might not be recognized properly.
