Q: bootcamp windows 8.1 driver problems

First off I have early 2011 MBP and trying to run windows 8.1 with bootcamp.

 

Curently, I have windows up and running but with a few issues. Everything went according to plan installing windows, however when I tried to install the drivers from bootcamp utility windows would crash at 'installing intel graphics' and as such the driver installation never completed. I got around the issue by removing the intel drivers folder from the USB and then re-running setup, everything worked except obviously no intel drivers were installed. So atm, I have no sound and I assume a graphics driver issue as I can't open metro tiles (including PC settings)?

 

Any idea on how I can install drivers to fix this?

    Did you install Windows using an EFI Boot?

    On a preUEFI Mac, using EFI boot will cause Graphics and Audio issues at a minimum. You will need to use a MBR method for it to work properly. On a dual GPU MBP, CSM-BIOS does not expose the Intel integrated GPU to Windows (because Windows has no drivers for switching between the two GPUs), but as you can tell, EFI Boot does not know that, hence your issue.

     

    From BC info.plist...

     

    <key>PreUEFIModels</key>

            <array>

                    <string>MacBook7</string>

                    <string>MacBookAir5</string>

                    <string>MacBookPro10</string>

                    <string>MacPro5</string>

                    <string>Macmini6</string>

                    <string>iMac13</string>

            </array>

    excellent. Okay, so the reason I used EFI boot was because I got the message 'this mac can only run windows 7' or something, and I want to run windows 8.1. However, I have litterally just read a post about just installing windows 8.1 anyway through bootcamp from DVD and just downloading the latest support software 5.1.5621 and install that in windows, i'm assuming this should work?

    From BC info.plist, Win7Only models are

     

        <key>Win7OnlyModels</key>
        <array>
                <string>MacBook7,1</string>
                <string>MacBookAir3,2</string>
                <string>MacBookPro5,5</string>
                <string>MacPro2,1</string>
                <string>Macmini4,1</string>
                <string>iMac10,1</string>
        </array>

     

    Yes, W8.1 should work in MBR mode (not EFI mode).

    I have a problem. I need GPT for Windows 8. I have formatted my USB Flash Drive in GUID-Partition..., but when I install the .iso on Boot Camp-Assistent the partition table switch to Master Boot Record. Do you have solution for that?
