Hi,

I think a already asked this question, anyway.

I have an Acer Aspire V3 771, i want to know if i can disable the Nvidia card when i can't boot after installing.

I can boot on OS X install without any flags, after installation, i get black screen so i can't disable nvidia card and only use Intel HD 3000.

I don't have option and my bios and i thinking about flashing the bios but i read 'cause it's an UEFI, it was risky.

But, i want to know if a can totaly disable nvidia card with an dsdt or delete some kext ?

I have too Windows 7 so if i need to delete something on hdd, i can.

Thank you, bye.
