I try to install Mountain Lion 10.8.2 on my laptop Acer Aspire V3-571G. Here's the specs, even if they are in my sig :
CPU : Intel i7 3610QM 2.3GHz with Turbo Boost up to 3.3GHz
GPU : HD4000 integrated / Nvidia GT 640M working both with Optimus Technology3
Memory : 8Gb DDR3 Ram
Network : Broadcom BCM43228
Audio : Realtek ALC269
Wifi : Broadcom BCM43228
Hard Drive : 750Gb SATA II (or III ?)
Partition Sheme :
Windows 8 EFI NTFS Primary
Windows 8 NTFS Primary
OSX FAT32 Primary Active
Data NTFS Logical
Not many options in BIOS, only switch for GPU (Switchable/Integrated) and AHCI/IDE. Actually they are set to Integrated and AHCI.
What I do
Well, I do so many things I can remember exactly what. I try to expose the problem clearly. Early install with Tony tools was successfull, only problems with chameleon at boot... Tired of the tools I decided to make it work myself, with insanelymac support off course.
The laptop had already boot some Mac OS X Mountain Lion before this, it can handle it.
I follow your installation guide twice. I follow this guide on Mac OS X Mountain Lion VMware Workstation.
I attach the ready USB Key to my laptop, booting up and select the key with -v flag and got Kernel Panic related to AppleCPUPowerManagement.kext. Isn't weird ? I have NullPowerManagement.kext installed.
So, no problem, I delete AppleCPUPowerManagement.kext but now facing another error I see already : PCI Configuration begin .... Still Waiting for root device...

I think about AHCIPortInjector.kext but I really don't know if it's the good solution. I put AHCI_Extended_Injector.kext System/Library/Extentions but same error...
I also have a weird error since my first install of OS X on this laptop :
"Error Encountered While Starting Up... Pausing5 Seconds..."
Here I am, i'm sick and this is my only occupation at the moment.
Hope you can see what's wrong.
Thanks for your help.
