Thanks for the reply, and my specs are; intel core i3 processor, a gigabyte GA-Z68MA-D2H-B3 mother board and a sapphire AMD radeon HD 6670 graphics card, and its currently not running any operating system. Oh and i also have corsair 8 gb of ram and antec hcg 520 watt power supply .. not sure if those two things matter at all

I would double check my BIOS settings are set correctly since it looks like it is complaining about waiting for root device.

Never mind I was able to fix it by plugging the boot usb into a usb 3.0 slot then typing in PCIRootUID=0 before sekecting the usb option, then when the apple screen loaded up I switched the usb from a 3.0 slot to a 2.0 slot and it worked but thanks for your help !
