Problem Booting up installer on Lenovo Thinkpad T61

[creepish.longman]

Hey guys,


I have accidentally screwed up my laptop - Thinkpad T61's MBR, so i thought since I need to go through the process of reformatting, I might as well do a hackintosh this time round.

I have followed through the tutorial for creating a yosemite boot up drive.

• After boot up using the flashdrive created using unibeast, I got past Apple logo booting screen (loading phase 1).
• However after the Apple Logo loading phase has finished, there is another round of loading that shows nothing but just a loading bar (loading phase 2).

Ideally I should get to the language selection phase of the installer once this logoless loading finishes.

My problem is that i can never get past loading phase 2.

I have tried booting up with or without [-v -x] or [-v -x GraphicsEnabler=yes] and a bit of other flags.
I realized that my problem is not really with loading phase 1 which most people are experiencing.

Based on my observation, if I boot up without commands, i can get to about 20% in loading phase 2.
If I boot up with any of those commands, I get up to 5% of loading phase 2 and get stuck.

Also for a control test, using the same flash drive on a dell laptop, I can get past both loading phase 1 and 2, and successfully begin the Yosemite installation process.

Can someone please give me some hints as to where the problem might be?

Refer to this guide: http://www.tonymacx86.com/yosemite-...-booting-os-x-installer-laptops-unibeast.html

You will need at least GraphicsEnabler=Yes for your nvidia device, and will probably need to do additional research for how to make it work with the internal display (DSDT patches specific to your device).
