Can not get to the installation screen (UniBeast + NVidia Card)

Hey!

I've used UniBeast to prepare a usb drive to install OS X Mountain Lion.
When I boot from that usb drive, after a few seconds the fan of my graphics card gets quiet (as normal) but i can not see anything. I tried -v, -x, PCIRootUID=1 and GraphicsEnabler=No - but none of them help. My graphics card is a NVidia Geforce 9800 GT and it works fine with Lion.

Has anybody a solution for that issue? :) Thanks!
 
What I did when I had this was use the ATI kexts and bundles from /System/Library/Extensions and placed them in my unibeast usb and it seemed to work :)

Okay. I'll try the same with the GeForce Kexts from my Lion partition.

EDIT: Does not help. Same issue.
 
I also put the NV Enabler 64.kext from MultiBeast into System/Library/Extension on the usb drive and now it works without any bootflags! :)
Thanks for the tip!
 
Had Problems with my GTX 460 / 768MB...

SOLVED WITH UNPLUG THE CARD AND USE MY INTERNAL HD3000 VIA HDMI... THIS WORKED... AFTER INSTALLATION I HAD TO REACTIVATE MY GEFORCE CARD AND BOOTED FINE :)
 
Recommended Hardware GA-Z77X-UDH5 Cannot Boot to Install Screen with 6870 Video

I am using IVY Bridge i7 on a Gigabyte GA-Z77X-UDH5 with a 6870 Video Card. I get as far as the Unibeast logo and prompt for booting. However, none of the flags I use get me to the install screen. My guess is that there needs to be Kext's for that Video Card. I am trying to boot from the built in 4000 card from the mother board to see if that will work first and than add the 6870 Later.

Nope that did not work either. The system reboots when it tries to get to the installer screen.


Has anyone used this hardware and had a successful boot to the install screen?

Thanks in advance.

This worked for me too. Thanks a million.
 
Guys try starting this process over.

Remove your card before booting from unibeast
install ML and dont touch any kexts during this

once finsihed re add graphics card.
I know this is an issues with 6xxx cards not sure about anything else.
