I have a lenovo g780 with a core i5 processor. I have been trying to install mountain lion for a while now. Everything I tried I get still waiting for root device error.
So i finally tried to make a vanilla usb using http://www.insanelym...-for-beginners/

I still get still waiting for root device error. My bios is set to ahci. The only other mode is compatible and i tried that and it still didnt work. Help. Please

with USB, problem is not AHCI/sata. Try PciRoot=1, USBBusFix=Yes (hope I typed those right) or changing USB settings in bios

Ok, I probably had the syntax wrong there, but if you looked up the right way and tried that, then that's fine. What's the device ID for your intel sata controller?

OK, your fine there. After also trying -x -f -v (which you probably already did)..... And I'm glad you mentioned this; SATA WARNING: Enable auto-activate failed -is very likely due to a hardware failure (or partial failure) such as bad or loose sata cable, failing HD, HD firmware issue, etc.

I was able to bypass the issue by using niresh's distro. Everything worked perfectly.

can you tell me what options you used both at boot and what drivers/kext's you installed for this lenovo? Mine is HD 4000, Core i3, 6gb ram, 750gb HDD AHCI turned on.

I used the folder you attached, but it detects my CPU's graphics as HD 3000 and not HD 4000, USB does not work, and neither does ethernet. Etherner is Atheros, I have usb 2 and USB 3 on this laptop, and the Atheros wifi does not get detected (i think its 9285 or 9287)

This link has wifi kext

http://www.osx86.net...ros_ar9285.html

get your smbios from chameleon wizard and put it in the extra folder. In chameleon wizard under org.chameleon.plist in device properties put in the following code for Intel HD 4000 graphics

7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000004006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31

I think it is because you have the wrong smbios.plist. In chameleon wizard under smbios.plist you should create a new one according to your processor. This will correct the problem. So the smbios you put from the t420 might be the wrong one for your computer.
