I have problems installing my Mountain Lion
I have HD6850 graphic card and I had to remove the Ati6000controller.kext, because I got the white screen. I succeeded to install the OS to my hard drive, but when I boot first time(after it has copied the files), the wheel just keeps spinning and nothing happens...I have tried with different boot flags and for example -v does not give any error message, it just stops. I tried with -x and after a while a gray bar appeared under the apple logo(I suppose this should happen?). It kept loading a while until disappeared and the wheel kept spinning.
Any suggestions what I should do?
EDIT: When booting on safe mode, it loads the grey bar about 1/3 until it disappears and the wheel continues spinning.
