Stuck on IOBlueToothHCIControllerstart (Mavericks installation)

[JesterKynes]

Hey guys.

I've been trying to install Mavericks on an Asrock z77 extreme 4. I've flashed the modded BIOS (2.7) from another thread in the forums. I'm using a unibeast boot usb, with the bootflags -v PCIRootUID=0. I've also tried using -x and GraphicsEnabler=no. I keep getting stuck at [IOBluetoothHCIController][start] -- completed. If you guys have any suggestions, or if any of you have gotten mavericks to work on a Z77 extreme 4 it would be much appreciated. I've been stuck for about two hours

Cheers and thanks in advance

are you using a video card? if not you should be able to boot with the HD4000 onboard gpu with -x
