Mavericks 10.9 at Acer Aspire V3 771G

Hello there,
I am trying for 2 days now to install Mavericks on my Acer.
It is all HFS+ formatted and i can install Mavericks with Unibeast using the flags
PCIRootUID=1 GraphicsEnabler=Yes -v.
Once it is installed it tells me to reboot. After rebooting i can choose between my USB Device and Mavericks.
When i launch Mavericks without any flags, grey screen with black Apple Logo appears with the loading circle below it. It lasts for about 2-3 minutes then the screen turn completely black for even hours.
I tried different flags, such as mentioned before plus -f -v -x ncpi=0x3000 dart=0 and so on.
Can someone help me?

My Specs:

Intel i7 3630QM 2,4 GHz
nVidia GeForce GT650M @2GB
IntelHD 4000
16GB RAM
Standard HDD

Best wishes and hopefully someone can help me

Boot "-v" to diagnose. You probably need boot flags to enable your HD4000. The flags depend on your screen resolution.

I was able to reinstall using the flags as mentioned before (GraphicsEnabler=No IGPEnabler=No), but when i try to boot with the exact same flags plus "-v" it wont load any further then this:
