Situation:

  • (See also for context: a previous question)
  • Cannot access Win7 (bootcamp) system via screen, as AMD GPU is bust
  • Win7 Safe Mode does not help
  • Can run OSX partition as managed to manually disable AMD drivers via single-user boot

So...

What I want to do:

What I want to try to do is disable the Win7 AMD (Radeon HD 6490M) driver via Mac's Finder.app (have NTFS rw capability).

How would I go about that? Is it possible?

Follow-up question

Can I then manually install a Intel HD Graphics 3000 driver purely via Finder?

Device configuration is stored in the registry file C:\Windows\System32\config\SYSTEM. However, I'm not aware of OS X having any way of editing a Windows registry file.

If you want to edit the registry without using Windows, you could use something like Offline NT. You will find keys related to display driver configuration under HKLM\SYSTEM\CurrentControlSet\Control\Video.

Rename the AMD drivers (atikmdag.sys and atikmpag.sys) in Windows\System32\Drivers. Now Windows should not start the AMD GPU.
