Still waiting for root device (Incl. Picture)

[SeloMac]

Hi everyone,

I made an unibeast USB drive and followod everything step by step.
But when i try to install the OS it says "Still waiting for the rood device".

(This picture i get while trying to boot)

I tried GraphicsEnabler=No and some other but it didn't worked. I tried to plug the USB stick to another port and it didn't helped me out also. I think my BIOS settings are ok. because i don't have so much options to change (only thing i changed is AHCI & RAID instead of IDE).

My specs:
HP Z600 Workstation
Intel Xeon E5520 @2.27GHz
8 GB of RAM
64 Bit
AMD Radeon 6800 Series

Can anyone please help me out?

I believe your problem is graphics related. See this quote from the 10.8 guide (http://www.tonymacx86.com/61-unibeast-install-os-x-mountain-lion-any-supported-intel-based-pc.html):

Special Instructions for AMD 6xxx Graphics Cards:
There is an issue with AMD 6xxx cards in Mountain Lion. We recommend using an alternate graphics card or onboard Intel HD 3000/4000 graphics for the entire process. After you're fully installed, you can switch back to your 6xxx card.

In your case, I don't think it is possible for you to use the onboard graphics (Xeon doesn't have it), so you will probably have to temporarily remove all ATI/Radeon kexts from the USB, or do like the guide says and use a different card that is better supported during the install.

And how can i delete those kexts?

I only see the mountain lion app to install on the usb and nothing more...

The folders are hidden. You can show them with:

# in Terminal
sudo chflags -R nohidden /Volumes/Installer/System
sudo chflags -R nohidden /Volumes/Installer/Extra

(assuming your Unibeast USB is called 'Installer')

Note: You will want to save backups of the kexts, because you'll eventually need them.
