Currently I have trouble entering UEFI after setting Ultra Fast Boot. I'm using
Mother board: Gigabyte GA H87N Wi-Fi rev 2.0
Graphic Card: Palit GTX 660 Ti 2GB.
Memory: 2x4GB Kingston HyperX 1600
HD: 1TB WD Blue 7200x
So let's start from the beginning. I've already done an UEFI win 8 install on GPT partition. After that I tried to fiddle a bit with the secure boot. After a custom install of secure boot key, the first sign of trouble start: I got blank screen and can't boot.
So I found out that I can circumvent the problem by unplugging monitor from graphic card and plug into mother board instead. After it boot, I plug it back to the graphic card and it work just fine. And after that first boot, I can boot it normally (most of the time) direct from graphic card. There are several time I need to do the unplug trick though.
At the time I can still enter UEFI by shift+click restart button on windows power menu, or through setting recovery menu. So I enter UEFI, switch secure boot mode from user to default (which still keep the previous keys and still keep secure boot enabled), disable CSM, both of which seems to somewhat help stabilizes my booting. And then I also change fast boot from just being enabled to Ultra Fast Boot.
I know that UFB requires GOP compatible graphic card and judging by the card's temper when enabling secure boot it doesn't seem likely to be the case.
But surprisingly it works. I can boot in 12 seconds flat from off to login screen using 7200 RPM hdd.
So now that I see that UFB works, I wanted to check some more setting on UEFI, perhaps disable secure boot altogether, or at least delete the keys. But I found out that I can't enter UEFI. When I shift+ click restart, there's no troubleshoot menu. There's only 3 menu: return to Win8, use device boot (DVD/USB/network), turn off.
Is there any other option to enter UEFI other than using Shift+click restart, I've tried setting recovery and still the same result.
And of course since UFB is activated, there's no longer logo screen on booting, therefore pressing Del key is definitely useless.
Additional note: I've contacted Palit asking about their VBIOS-UEFI compatibility with BEFORE enabling Secure Boot or Ultra Fast Boot. And I've just now received their respond saying that the card wasn't configured for UEFI BIOS yet. I know, it's my fault for being impatient and twiddle all the setting too soon. But frankly I'm surprised that the graphic card CAN accept Ultra Fast Boot setting, albeit might be a bit temperamental. Palit have promised to sent me an update for VBIOS. So I'd like to ask as well, is it safe to update VBIOS without any access to motherboard BIOS?

Just reset CMOS and it will return back to default settings (no UFB or FB).
That would require unplugging motherboard battery from the board right?
After that I would have to enter BIOS via Del key from POST screen?
Is there going to be any other side effect from doing that? Windows recognizing the board just fine or something else?
Just wanted to be sure of what I have to do. Since it's a mini ITX case, unplugging battery would require me to dismantle everything, since the whole board is blocked.
And the other thing, is it safe to update VBIOS without BIOS/UEFI access? Because if it is, I might try that first before attempting to dismantle.
1. Yes, resetting CMOS require take out the silver battery on the motherboard, or by using jumper (you will be able to find it in manual).
2. Yes, you press the BIOS setup key to enter BIOS afterward.
3. There is no side effect, it's only the BIOS settings, does not affect any software.
4. Reading this should help you figure out everything about VBIOS http://www.gigabyte.com/WebPage/40/index.htm
I would just reset the CMOS first, everyone who mess stuff up in BIOS does it. Quick and easy way to solve the problem, and the battery should be reachable unless you have a giant cooler or the GPU onto of the motherboard.
Make sure you disconnect the plug on your outlet before attempting to take out the battery, and discharge yourself.
