Can't boot without the -V -X flags

[gv260ea]

Hi, I managed to install OS X 10.10.2 on my HP 8560P. However I can not get the gpu to work. When i boot without any flags during the regular loading screen the screen turns black. When i add the safe mode flag it boots with low resolution.

 

Here is how i installed the OS X 10.10.2

Booted off the clover installer i made with the files downloaded from this post "http://www.tonymacx86.com/threads/guide-to-install-yosemite-on-hp-laptops-with-clover-uefi.143675/"

Installed the OS

I then booted with the usb, this time I selected the HDD that I had mac os installed on with the -x -v flag

Then I ran PBI CE.

 

Here are the specs of my 8560P

AMD 6470M

1600x900 Display

i5 2520M

8GB Ram

QM67 Chipset

*NO SWITCHABLE GRAPHICS

 

Thanks in advance
