iATKOS 7 on DX58SO mobo with i7

[t3ofil]

Hello,

I'm trying to install iATKOS 7 on this configuration:
DX58SO mobo, i7 920 processor, BFG videocard with intel GTX 285 1024 MB chipset, 8 GB of Corsair DDR3 at 1333 MHz, Seagate Barracuda 1 TB HDD.

It boots normally with "busratio=20" command and installs normally with no changes in the customization. I've chosen Mac OS Extended (Journaled) as a volume format for the HDD without partitioning it (I didn't know how to partition anyway). After the installation completes and it reboots, it freezes at this image:

As you can see, there's a small "banned" sign that appears there.

What could be the problem?

I also tried by installing nVidia GT200 EVGA with NVEnabler in the customization menu, a hint which I found around... but still the same result.

Thanks in advance.
