UniBeast USB

[musiclee]

can we please have a step by step on how to create a USB drive to load Mountain Lion onto so we can do a fresh clean install?

i guess what i'm looking for is the "full OS X Mountain Lion retail installation and upgrade guide"

For me doesn't work, Stops at apple logo.

maybe make this a sticky somewhere,
and put it in this 10.8 Laptop Support Section

For me, (I've done all the boot flags I can think of), I get a black screen after the grey Apple logo or if I do a Verbose boot. So I just spent $20 on an app icon.

I'm on Lion 10.7.4

i7-820QM
NVIDIA GeForce GT 240M
Corsair Force 3 480GB SSD
8GB DDR3 1333 RAM

I tried seeing if hooking up to HDMI with GraphicsEnabler=Yes I would see a screen but nope.

My biggest fear is Apple no longer supporting the 2XX series from NVIDIA but that doesn't make sense. I will see if anyone else gets this.

Okay, so here is what happens when I try to install ML with UniBeast.

Pics:
Select USB HDD from BIOS (F12)

Enter in my flags (I've tried numerous ones)

look at the smbios.plist file in the extra folder.
there is another extra folder within, that has a diffent smbios.plist
and that one will boot your graphics card.

(It does for me, but I have the corrupted video with me Intel HD 3000)

IF anyone out there got it to boot with that videocard and has a normal screen, please let me know how you did it.
I'm stuck for almost 3 weeks now)

Solved. On another thread someone said to boot with PCIRootUID=0 only. He had a 560 ti. Yay!

 

[pka4916]

are the boot options case sensitive ?

Like EnableGraphics vs enablegraphics when you enter something for the bootup ?

I'll try this with my 560Ti. Thanks

I totally agree with this request. I found the new unibeast 1.5 guide for ML lacking a full step-by-step instruction as it was done for Lion.
