Nvidia GT540M not detected anymore in Windows 7 after successful Mavericks installation

[TGudde]

Hi there,

 

I recently successfully installed Mavericks 10.9.2 on my samsung rf711 laptop.

It took me a while to get the intel hd 3000 working, but all is running smooth now.

 

There is only one problem: 

 

When i boot in Windows 7 it doesn't recognize my Nvidia GT540m video card!

It's not in the device manager anymore.

 

It only showed up when i completely broke my hackintosh partition due to a kernel panic.

 

How do i get my Nvidia card back so i can use it in windows again?

 

Thanks in advance for any help!

did you shut it off in bios to get osx running i think it's called optimus?

My bios doesn't allow me to shut off a video card. My card indeed works with optimum, but that doesn't make a card disappear from the device manager when it's not being used. Trust me
