Black screen on installing yosemite

Recommended Posts

I am trying to install Yosemite 10.10.1 on my lenovo laptop, Here are the specs:

Model : Lenovo g 50-80

Processor: Intel i5-5200U

RAM : 6 Gb

Graphics: AMD R5 230X (2Gb)

BIOS: B0CN75WW

 

  I have managed to boot from USB by enabling Legacy Support on Bios. After selecting yosemite disk from charmelon with default intel kernel, It brings me to a screen with a Hackinthosh logo.

This screen doesn't even have a progress bar. So i tried waiting about 1 hour and nothing happened. but the usb light is still blinking indicating data transfer.

 

When I Enter in verbose mode it shows some BIG letters scrolling through screen and in about 10-15 seconds, the screen goes blank (back-light is still ON and the USB led is also blinking ). I think the mode is switched to laptop resolution 1366x768 and showing a blank screen.   I did these things :

1. Changed kernel and tried to boot with all /amd variations

2. Tried every flags.

3. used Graphicsenabler = no / yes

4. typed setup_var 0x18c 0x3 to change dvmt from an efi shell and it gives me an error 0x1111111111111111a

 

 

Please help!!
