Pgr456 Posted November 5, 2012 Share Posted November 5, 2012 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.

iFIRE Posted November 6, 2012 Share Posted November 6, 2012 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 Link to comment https://www.insanelymac.com/forum/topic/284176-help-with-mountain-lion-on-lenovo-b560-problems-while-loading-installation/#findComment-1865394 Share on other sites More sharing options...
