FuriousEnchiladas

Hello, I'm having an issue with getting my egpu setup properly detected. First of all, i have a Windows 8.1 partition that was set up by Bootcamp Assistant, I can get the egpu detected, but the Device Manager lists it as a Microsoft Basic display adapter and says "Code 31 This device is not working properly because Windows cannot load the drivers for this device. The driver trying to start is not the same as POSTed display adapter" Uninstalled the Nvidia drivers, used DDU to clean up Nvidia drivers completely. Installed latest drivers from Nvidia website with the same result. Nvidia website scan only picks up the onboard GT650M card and the egpu is still detected as a basic display adapter in the device manager. My specs are 15" Mid-2012 Macbook Pro, Intel Hd4000 and Nvidia GT650M 512MB graphics, Akitio Thunder2, GALAX GTX970OC, Dell DA-2 I think maybe the problem is that I need to delete my partition, and do a BIOS or UEFI installation of Windows. Is that correct? Or maybe there is something else I'm missing?

Thanks for the reply, I should be good to go then. Just waiting for parts for my build.

Hi, bsohn. Im working with the same laptop as you have and I was wondering if it is necessary to have a fresh install of windows? I've had a windows 8.1 partition for quite awhile now. Though, all the projects I have read about start with a new installation.

@Dschijn, I have misunderstood. In the text of Morv's photo, it mentions that it is a paperclip being used on the DA-2 as the "switch". I thought seefew was referring to an on/off switch (or spst switch I believe it's called?). Thank you.

Could you possibly link this pic? I searched for it and looked for it under Morv's build but I did not see it. By the way, thanks for the wealth of information you have all put up. Despite having zero experience with this, most of it is easily understood.
