HELP: can’t boot without usb.... (mobo: B75A-G43)

Please help me. I want to run Mavericks 10.9.4 on my PC
I made installer USB with UniBeast 4.0.2 with newest Mavericks 10.9.4 and installed it..
I installed it on my 500GB external HDD (usb 3.0, but tried on USB 2.0 port)
I have disabled in BIOS:
VT-d virtualization
set limit CPUID max - disable
set execute disable bit - enable,
set intel virtual - disable

MY PC:
CPU: Intel Core i5 3570
Motherboard: B75A-G43
GPU: GEFORCE GTX 660 Twin Frozr 2GB
8GB DDR3 RAM


Fast forward... Everything went quite good, till the step i should install drivers using Multibeast. I try free dsdt, with custom dsdt that i found for my mobo, and easy mode too but everytime i cant boot without usb and after install Multibeast drivers, i cant boot with usb neither, only with -x

I read that problem can be my GPU (GEFORCE GTX 660 - TWIN FROZR) but i think its something with bootloaders.

I took some pictures from boot with -v. Those are pictures from multiple options i tried with Multibeast.

bump! please

I have the exact same problem even though I have other specs.
