Hey there,
i try to boot to my USB. I installed installed Yosemite on this USB with Unibeast.
But now, if i want to boot from this USB wit "-x -v" it stucks at [IOBluetoothHCIController][start] -- completed.
If i want to boot with "-f" or "PCIRootUID=0" i come to a white screen with an Apple Logo and a loading bar, but the loading bar stucks at ~25%.
Here are my pc specs:
i5 3.2 GHz
GTX 750Ti
12GB Ram
Hope for an working answer
