Hey i need help. I had long time a snow leopard running in an virtual machine, but now i want to install mountain lion on my Lenovo B560. But i can't even boot to the installation menu so i used the verbose mode i added the picture in the attachments. I tried different flags but nothing worked. It needs something about 30min to show those 4 timeouts after that nothing happens. What can i do to get it working? I used this tutorial: http://thetecherra.c...oshosx86-video/ Hope someone knows how to fix.

if you are using USBInstaller method, delete all Graphics kexts and AppleintellCPUPowerManegement.kext, backup first, and boot with this flag: -f -v -x GraphicsEnabler=No npci=0x3000 cpus=1

and put your hardware in your signature for guet support
