Stuck at "Still waiting for root device" error

[hitz2000]

I am trying to do a fresh install of 10.10 and I have tried many different bootflags and keep getting stuck at "Still waiting for root device". I followed the buyer's guide for the customac socket 2011 guide, and don't understand why I cant get past this.

UPDATE: I got the USB to mount to the root_device, but now on the last line it states "Darwin Bootstrapper Version 2.0.2; root: libxpc_executables-559 .30.1˜2/launchd/RELEASE_X86_64"and stops there. what does this mean now?

Try booting with "dart=0 -f -x -v cpus=1"
