Q: AMD Radeon R9 M370X not recognized by Windows 8 partition. Mid 2015 15 inch Macbook Pro

My AMD Radeon R9 M370X isn't being recognized by my Windows 8 partition. It only lists the "Windows Basic Display Adapter" in the device manager. I've tried installing the boot camp drivers, AMD drivers, reinstalling Windows, updating drivers, uninstalling drivers, and I can't get anything to work. Any ideas?

 

The gpu runs great on the Mac side, Windows just can't see it.

MacBook Pro (Retina, 15-inch, Mid 2015), iOS 8.3

    OK. Windows applied many updates and now is willing to start downloading Windows 8.1. However, it gets about 60% through the download process and then says "Sorry, we couldn't update the system reserved partition" and stops the process. I restarted it, but it happened again the same spot. I believe I've got to get to Windows 8.1 to correct the video driver issue, but am stopped by this latest roadblock.

    Can you post the output of diskutil list? The MSR partition exists only if your Windows was installed using EFI boot. The output will show what your installation type is - BIOS or UEFI? You can get the same information using MSInfo.

    Can you post the output of sudo fdisk /dev/disk0 ? There is a MSR partition for EFI-based installations. You do not have it, yet your installation is UEFI according to the output you posted.

     

    Is it possible to clean install W8.1 rather than a W8 -> W8.1 upgrade?

    Funny you should say that. I am actually downloading the W8.1 iso right now. I'll have to switch over to the mac book to do the sudo command. Will post that in a moment.

    Here is the output of the sudo command:

    Disk: /dev/disk0 geometry: 60821/255/63 [977105060 sectors]

    Signature: 0xAA55

    4: 00    0   0   0 -    0   0   0 [         0 -          0] unused

     

    Assuming that checks out - and now that I have the W8.1 iso - should I start over with BCA, delete the current windows partition and just start from scratch?

    Problem solved! I followed the Boot Camp instructions and did a clean install using the W8.1 iso image. The installer updated the boot camp drivers without a hitch and the screen resolution looks great. Thanks for all your help!

    Can you verify that the drivers for the GPU are the Apple BC drivers?
