I started with a Snow Leopard Hackintosh Setup with the ff:


Almost the same setup from Lifehacker.

Followed the bios correctly

To make it short it was a successful install.

Recently i decided to try out Mountain Lion Hackintosh install and followed this

Problem is after booting into the USB i only reached the part where i can boot from the USB and after selecting my installation i am getting the apple logo and a few seconds a black screen.

Tried reading and used the following boot flag commands like
GraphicsEnabler=No
-v
But did not get a different result.
Still apple logo and black screen will follow.

How Do i fix this one since i am done with snow leopard and time to move on.
Thank you!
 
After applying the following commands

GraphicsEnabler=Yes PCIRootUID=1 -v -f -x

This is what i got. Please download screenshot.

Thank you for assisting. Hope the screenshot is readable enough.
Cheers!
 
Here's another try


Commands used:
GraphicsEnabler=Yes PCIRootUID=1 -v -f -x -s
[FONT=tahoma, helvetica, arial, sans-serif](in the end i put -s for single user mode)[/FONT]


See screenshot for results:

I am having the same problem:

mobo: asus h87i-plus
cpu: i5 4670k

After chimera loads up, and I choose "Mountain Lion" (the unibeast drive), it loads the apple logo briefly, then goes black, and tries to boot again.

I tried it with -v, and here is the last thing before it goes to the black screen:
