Weird Screen Corruption + Prohibited during Boot

[FriedCPU]

Hi,

No matter what I try this is all I keep getting...

 

and in non-verbose 

 

my specs and methods are...

 

Asus x79-Deluxe, 4930k, 64GB RAM, 2GB EVGA GTX 770, 250GB Samsung SSD.

 

I prepped my USB like it says here http://www.skylineosx.com/yosemite-installation-guide/

as the createinstallmedia method caused clover todo nothing when I selected the install drive.

 

I have loaded the latest FakeSMC into S/L/E which is http://www.insanelymac.com/forum/files/file/266-fakesmckext-yosemite-1010/

but I have also tried the one modified by RampageDev for Yosemite. Both in S/L/E and EFI/CLOVER/kexts/10.10, makes no difference.

 

I am using EmuVariableUefi-64 and OsxAptioFixDrv-64 as without them I just get a reboot as soon as Clover loads the kernel.

 

I am using npci=0x2000 darkwake=0 kext-dev-mode=1 -v   but have also tried with -x and -s too.

 

Cannot find anyone else who has had the same problem.

Thanks for any help anyone can contribute

Can you get a better pic? I can't really see where it's hanging... Post your config.plist. For some reason, my girlfriend's amd build does this if USB injection is enabled. The prohibited thing usually happens when you get "still waiting for root device" though. Make sure you are booting in AHCI mode (should be default on your board anyway), and that your board doesn't need any special kext or injection for SATA (it shouldn't AFAIK).

Well after a couple more hours of pulling my hair out, thinking about the 'waiting for root device' error, it occurred to me to try the USB2 port instead of the USB3...

 

Feel like such an idiot for not trying it sooner, after remaking 6 or so install usbs with various combinations, they probably would of all worked if I had tried it in a USB2 port.

 

Ahwell, thanks for your help jamiethemorris, and hopefully this will save someone else from going through the same pain I did.
