Pro, at this moment there are not drivers available for Windows 8.1 since this is a preview version.
Regarding the issue you are experiencing, we got the following workaround. Would you please give it a try and let me know the results?
1. Go to the secure boot options on BIOS
2. Enable secure boot (if disabled)
3. Check on the option that says “Install Intel platform key”
4. Press F10 to save changes and restart the system
@sylvia_intel Thanks for your help.
I tried you steps but that didn't fix it. Any other ideas?
By the way, Windows 8.1 should be supported because it isn't a preview version anymore! It got released on 21st october. But I don't think this is a Windows problem because Windows boots up, but the bootscreen doesn't show.
If I plug the Display into the integrated graphics card, I can see the boot screen (as already mentioned). But I need to use the graphics card because of the better performance.
I think this problem is related to secure boot and invalid or unsupported integrated graphics driver.
Because if I disable Secure boot, the mainboard automatically switches between integrated and graphics card without problems.
Pro, would you please access the following link and use the Intel® System Identification Utility: http://www.intel.com/support/siu_la.htm?wapkw=%28siu%29
That will generate an 8 digits code called Report Reference ID. Please let us have that code, this will provide us information on what is being detected on your system. In addition please fill in the following information:
AA number and Serial number of the motherboard:
Memory manufacturer and part number:
power supply model number:
Any other device connected:
Once I received this information I will provide this behavior to the Engineering Team.
Here you go:

Other devices connected:
- GPU: Sapphire Vapor-X Radeon HD 7770 OC, 1GB GDDR5

One thing i found out:
I installed the most recent driver for Intel Graphics HD 4000 ( https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23323 ) but in the Device Manager the graphics card has a yellow error triangle. If I open the details page there is the following error: Code 43: Windows has stopped this device because it has reported problems. I already tried the steps as described here but that didn't fix it: Code 43: Windows has stopped this device because it has reported problems
Thanks for your help!
I have the same problem.
DH77DF, AA #: G40293-301, BIOS 0110.
I set the Secure Boot in the BIOS and now when I restart my machine, there is no intel logo, no ability to press F2 to enter BIOS and it boots straight to Windows 8.1,
Ironically, I enabled SecureBoot in hopes of getting rid of the "SecureBook isn't configured correctly" watermark and it's still there.
How do I get have into the BIOS settings? Do I really need to open my case and set the BIOS jumper to configure?
Same motherboard, same problem plus :
Now, even if I disable Secureboot my bootscreen stays black.
Like Pro, if I plug the monitor into the onboard DVI Port, I get the Video OptionRom authenthicate fail message whereas I never used to get that before activating secureboot.
Somehow, turning on secureboot broke something somewhere in the BIOS that cannot get fixed by a firmware update (I just updated from 0108 to 0110).
I'm considering purchasing a new graphics card, maybe a GTX760, but I'm unsure this will solve the problem.
PS : Turning off "UEFI boot" in BIOS seems to fix the issue but is an unacceptable solution.
When you enable Secure Boot, the BIOS must have UEFI drivers for all necessary hardware in order to support the use of this hardware during the boot process. The BIOS provides the drivers for the embedded features, including Intel graphics, but add-in cards, to be included, must provide their own UEFI driver (via OP-ROM). The authentication failure message is an indicator that the OP-ROM provided on the graphics card is not in compliance and/or does not provide the necessary UEFI driver. Look to the board's manufacturer for an updated OP-ROM that brings it into compliance...
