Hackintosh Yosemite problems

[hAyO]

Hello guys, I know it's been a long time since I last came in, and it's mainly because I don't have the same amount of time I used to have, and well, it's also been a while since I did any research and I only do it very occasionally.

The thing is, I'm preparing my 2 hackintoshes, the i7 one and the quad one... And I've had a paranoia or a very strange event, rather.

On the i7, whose machine is | Core i7 4770K | Asrock Z87 Extreme4 | 2x4GB DDR3 | GTX560TI.

I currently had Mavericks 10.9.4 installed (which I had trouble installing in its day), so I decided to install Yosemite since I already had a dedicated graphics card (GTX560TI) and it was natively supported by Mac. So I gathered my courage and tried it on a test disk... and wala, installation OK! with all the "boot args" or "boot flags" recognized and executed.

I noted the steps (I only used GraphicsEnabler=Yes -x) and it let me install OK, then I started Multibeast and everything was correct.

My surprise came when I saved the data from the disk where Mavericks was, and followed the same procedure... and the installer gave me an error in all cases.

Does anyone know what this could be due to? my BIOS version is 3.00 of said board.

Thanks!!

Currently writing from the Q9550 with Yosemite 10.10.

I reply to myself, and maybe it will be useful to someone with the same motherboard:

1 - We install Mac OS X with the motherboard and without the graphics connected. With the help of "GraphicsEnabler=Yes -x"
2 - We patch with Multibeast
3 - We restart to see that everything is OK.
4 - We place the graphics in the PC and indicate that the PCIe should be the main one.
5 - We start up and enjoy MAC OS X.
