No a lot of information to go off... but it could be that you placed the stick in a USB3 port. Try a USB2 port.

I have 3 USB Ports 2 USB 3.0 and one USB 2.0 I tried it in diferent ports but i allways get this error.
I have also tested different Bootflags but nothing works.

I used this guide for my usb stick http://www.tonymacx86.com/61-unibeast-install-os-x-mountain-lion-any-supported-intel-based-pc.html

What boot flags did you use to get to that screen?

Can you try PCIRootUID=0 -v and see what happens?

Also look in your BIOS for something called VT-d and disable it if it's enabled. VT-d is Intel Virtualization for Directed-IO.

Is your Unibeast USB created with 10.8.2?

ok i disabled intel virtualisation in the bios

i booted with this bootflag: cpus=1 PCIRootUID=0 -v

Edit: when i use cpus=1 PCIRootUID=0 USBBusFix=Yes -v

There is also an error: "EHCI controller unable to take control from BIOS"

Intel Virtualisation Technology in BIOS is VT-x. VT-d should be separate setting. Do you have both settings? Just make sure both are disable.

Do you have a setting for EHCI Handoff or XHCI Handoff in your BIOS? What are they set to?

You shouldn't have to use CPUS=1. What happens if you don't?

Can you try PCIRootUID=0 -v and see what happens?

Is your Unibeast USB created with 10.8.2?

i can only set virtualization technology <Disabled>
There are only three other options
fan always on
usb3.0 configuration in pre-os
and boot options
there i can set legacy support and the boot order.

if i dont use cpus=1 i get a kernel panic :/ but i probably fix it with the lapic_fix Kernel PKG Installer.
and it stops at "System uptime in nanoseconds: 1230042271"

Unibeast is created with 1.8

Edit: I read that i must patch the OSX Setup because I want to install it on a MBR HD with windows 7 is that right? If yes how can i do it?

You can try the same flags plus EHCIacquire=Yes.
