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

It didnt work, I still get the error. But before the error i get SATA WARNING: Enable suto-activate failed

[eep357]

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?

[besttech]

The intell sata controller device ID is 1e03.

[eep357]

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.

Thank You. So can i repair the error with the chkdsk utility from windows

I am also getting
AppleUSBEHCI unable to get device memory
AppleUSBEHCI Error uccured  (0xe00002be)

I have the same laptop. No matter what USB port i use nothing works. Also tried PCIRootUID=1, USBBusFix=Yes, -v -f no go.. any thoughts. Mine is a core i3 with USB 3.0, Hd 4000

Also i get EHCI controller unable to take control from BIOS, AppleUSBEHCI Unable to obtain ownership
then still waiting for root device.

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

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)

[c0rrupts3ct0r]

Anyone? I got ethernet working, I tried installing the Wifi kext on the Niresh disk (package), but still no wifi.

[iFIRE]

and where is your hardware? I send for you a folder by a Laptop Lenovo with the kexts, but if this work or not only you can know, I don't  have any Laptop

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

ok I got the wifi working, but i did your thing w/ chameleon wizard and it still shows HD 3000 w/ no acceleration, but I do have the right resolution. could it be that stuff that i put in for that T420 that i fire attached?
