Intel Motherboards : x99 taichi, ultra fast boot doesn't work + blue sc

I bought last week an x99 taichi and it's giving me a headache. 

I installed windows 10 using a rufus manual as GPT EFI as can be seen here

So, till that point I think I did everything fine.

After that, I used the computer fine for some days, today I wanted to tweak things and entered the bios.

I selected ultra fast boot and "windows boot manager + SSD option" as bootable device, restart andIt takes at least 25 seconds from cold boot to windows

what's wrong here? How can I get a 5 / 6 seconds boot like my laptop or the thousands asrock ultra fast boot videos from youtube? Why my windows installation doesn't want to boot without ultra fast boot on bios?

My bios options:

The computer:

no overclock:

5820K

32gb ram

1070GTX

no other pci used

5 HDD + 2 SSD, I boot from a 840 pro ssd.

I didn't touch any other thing in the bios. I am running the latest 1.4 bios from the last week.

I  tried with only the ssd connected, no other hard drive, still the same, ~25 secs. Also, that kind of "this will boot soooo fast that you will not be even able to enter the bios!". Well, nope, I always still get the menu of press sup to enter bios.

Also, I formatted the HD 2 times to see if was some fault mine. but, still the same.

Any help?
