Still waiting for root device

Question

Hi! I'm new on this forum. I want to install Yosemite with USB pendrive. When I try to boot it with "/amd64 GraphicsEnabler=No npci=0x3000" I have to boot with "GraphicsEnabler=No npci=0x3000" because I had "PCI configuration begin" message. In few seconds there's a crossed circle. I tried to boot it in verbose. The last line is "Still waiting for root device". I tried to fix it by placing GenericUSBXHCI.kext or Niresh's Still Waiting for Root Device Fix, but nothing changed. I have to boot with "GraphicsEnabler=No npci=0x3000" because I had "PCI configuration begin" message.

 

My specs:

CPU: AMD FX-4300BE

GPU: Gigabyte HD 7770 OC

MOBO: ASRock N68C-GS FX

RAM: 1x4GB DDR3

Ethernet: Realtek RTL8211CL

Audio: Roland UA-1EX

 

I hope someone will help me :)

Thanks

@siralex90 Can you attach a verbose picture with

"/amd64  npci=0x3000 -v" at the point where you get stuck with still waiting for root device

Yes, I tried "USBBusFix=Yes" and others boot flags many times, and when I disable USB Legacy my USB pendrive isn't recognized.

Laptop has Inel Core2Duo cpu and 500gb HDD and 2.5 gb of ram.
