This simple guide is not made for you to have a fully functional G75VX Hackintosh but to solve the main issues about reaching the desktop in Mavericks. So, to install Mavericks on this laptop follow this steps:
01 - Inside the file attached you will find a torrent to download a DMG image that some "hacker" did from an original Mavericks 10.9 but customized for this Notebook.
02 - Clone the DMG to an 8GB pendrive using disk utility. (Maybe you want to set the keyboard layout of the /extra/ folder of the pendrive just cloned from spanish to your language)
03 - Go to the BIOS and set:
Secure boot control = DISABLED
Launch CSM= ENABLED
Boot priority always from pendrive first
04 . Make sure the disk where you are going to install Mavericks is MBR
05 - Boot the pendrive and Install Mavericks. The system will reboot automatically
06 - Once again in chameleon partition selection screen, simply shutdown the machine.
07 . Extract the HD and attach it to an USB enclosure and put it into a Mac or Hackintosh.
08 - Navigate to /System/Libraries/Extensions of the just installed Mavericks partition and move NVDAResMan.kext to / (Just move it, don´t delete it)
09 - Install all the mandatory .pkg files in /_Stuff/Kexts/ folder of the pendrive and install all of them to the recent installed partition setting the location in each .pkg installation.
10 - Boot again from the pendrive and rechoose the mavericks partition you just installed and configure the system.
Untill here Mavericks boots correctly when you fire it from the pendrive. If you want to boot Mavericks from de HD you just go to the /_Stuff/BootLoader/ folder of the pendrive and install chameleon to the new Mavericks partition
