oh I got it now
Remove the X in the vgapnp.sys to bring it back to working state.
Whatever NVidia driver it is using do this:
1. Go to Device Manager -> Dislpay Adapters
2. Right-click on the nvidia card driver that Windows 7 installed -> Properties->Driver->Driver Details
3. Look for the file with extension '.sys'. It should point to c:\windows\system32\drivers' path
4. Follow the steps and edit THAT file with the same method as in my tutorial.
Your step 1 will be to start with default Windows 7 nvidia drivers installed. Then you will edit the file, unistall those drivers and on the restart it should not install it so you should be able to install your own drivers.
Tell me the results.
