Win8? first, you must disable driver signing.

Command Prompt (Admin) Win key + X Type:

bcdedit /set {current} testsigning yes

-> "The operation completed successfully" -> reboot -> Install drivers.

Exit test mode, cmd (admin).

bcdedit /set {current} testsigning no

->reboot.

Yup you're absolutely correct, I went to check the disable driver signing again and found out pressing "7" will reboot but it won't work and hence it confused me. I had to press "F7" while choosing the options. (which also clear stated in the menu, but I was too hasty which leads to stupid mistake)

Thanks again for your help. And sorry for the bad English as it's not my first language.

@J95

My apologies, quick one I am following all your threads including the one how to mod my nvdmi.inf

I have a m17 r3 and just got a gtx880m(clevo)

I had 344.11 NVidia download and I've tried moding the nvdmi.inf (which I pretty much sure this is the problem)

It ran pass the NVidia "Checking Compatible Scan"

After I choose a clean install it didn't install any driver.

Any chance if I can request a moded nvdmi.inf file for this to compare with the one I failed....

This post should pretty much go on the1st page of the post because this is such a useful information. This solved all the issue I had(including emotionally spending money on the 880m which didn't work until I saw this).

Thanks J95 again

I am trying it now, however if you follow this Threat from J95's reply from page 23 onwards, you will get all the information you need
