Post Instalation HELP

[Slimpasha]

Hello, people. First of all, I apologize for my English
My problem is this:
I can not find the way back, to the correct settings after installation using Multiboot (on Mavericks)
Can anyone explain me in detail that I choose settings for proper operation?
Technical details of my pc:

Micro: Intel Core i3-530 @ 2.93GHz Socket LGA1156
Motherboard: Intel DH55TC
Chipset: Intel H55 (IbexPeak DH)
Bios: TCIBX10H.86A.0048.2011.1206.1342 (Intel)
Audio: Intel 5 Series/34x0 Chipset PCH - High Definition (RealTek ALC888)
Video: Sapphire Radeon HD 4870 1GB GDDR5 (Video Chipset: RV770 XT) (ATI/AMD RV770/RV790 - High Definition Audio)
Lan: Intel 82578DC (Hanksville-D) Gigabit Network
HDD: WDC WD3200AAKS-00UU3A0

Several attempts by post installation at the most you get is the monitor without video signal.
From already thank you very much to anyone who can guide me

im not sure if you said that after installing kexts from multibeast you have no video signal? if thats the case have you tried GraphicsEnabler=Yes? im almost positive your graphics card needs GraphicsEnabler set to yes
