Have you set the SATA protocol to AHCI in your BIOS? I've seen this behavior when it was mistakenly set to IDE.

Trying to boot Unibeast USB? Make sure you're using a USB2 port.

If this is when booting the Unibeast USB, try different USB ports and try different USB sticks if you have them. Also check "-v" to see what the issue is. If "still waiting for root device..." then try removing then re-inserting the Unibeast USB when you see that message.

Your OP is not clear on which stage of the process you are on -- whether you are booting Unibeast USB first time, or whether you have already installed and are booting off the HDD.

I didn't install it already. it happeans when the apple logo is loading-after that i should be in the language step.
i tried with 2 ports, 2 disk on keys.

so yes the error is still waiting for root device.
tried to unplug and replud, didn't help.
also tried to unplud and plug to another port-didn't help
the ports are usb2
is there a simple solution ?
big thanks for your help !

This is usually only necessary with older hardware (which you haven't listed...)

Try booting with USBBusFix=Yes

Also there is a "Legacy USB" fix in Unibeast. And you might check BIOS options related to USB...
