Windows 10 Kernel Security Check Failure on a Mac Pro with Boot Camp

Would you mind going into a bit more detail regarding the WHQL drivers and what I should do? Disable any Apple/Boot Camp ones and install those (if so, how/where?)

Do you have any external peripherals connected to the MP when you switch to W10?

No, just the wired keyboard and Mighty Mouse. The Bluetooth ones are connected as well I think, but I prefer to have the USB ones for all the resets and such.

I assume you are referring to Update firmware on Mac Pro (Mid 2010) and Mac Pro (Mid 2012) - Apple Support.

Yes, exactly.

Hi! As of this afternoon, the reset-NVRAM-and-carry-on-as-normal trick doesn't seem to work anymore. I now get a BSOD every time, either within a minute of logging in or already during the login screen, if I linger around for a bit too long. So I can't run the Windows Update.

I can login in Safe Mode (with Networking), but then the Windows Update doesn't work. And I also can't download the Debugging Tools in Safe Mode. Below are Google Drive links to the last two Small Memory Dump files, if there's a way for you to open them.

Thanks so much for your help!

Hope this is correct (via Device Manager):

Driver Provider: Advanced Micro Devices, Inc.

Driver Date: 14/12/2013

Driver Version: 13.250.28.1000

Digital Signer: Microsoft Windows Hardware Compatibility Publisher

If I click on the Update Driver button, it says "The best drivers for your device are already installed", but I'm not sure if this is because it's in Safe Mode.

I did find this on the ATI website (https://www.amd.com/en/support/graphics/amd-radeon-hd/ati-radeon-hd-5000-series/ati-radeon-hd-5870) for Windows 10 x64 — Catalyst Software Suite (15.7.1 WHQL) and Radeon Software Crimson Edition Beta (Crimson Edition 16.2.1 Beta).

Would it make sense to install one or both of them? And if so, is it ok/possible to do it in Safe Mode? It's my only way in at the moment.

It is. Actually, at first I installed 1709, because it's what I had, but I got a BSOD soon after installing Boot Camp, so I then downloaded the latest ISO (1909) from Microsoft's webpage and did a clean install with that one. Not sure if it's relevant though.

I'll try to install the Adrenalin 19.11.1 from bootcampdrivers.com now.

I tried installing the bootcampdrivers.com one and while I could delete the existing drivers in Safe Mode (I now have the Windows Basic Display Adapter) I couldn't then install the driver itself, because when it rebooted into normal mode, I got BSOD within a minute and it restarted, and if I tried to install it in Safe Mode it said Detection driver error. In normal mode it does detect the card/driver and moves forward to give installation options, but then BSOD appears before it can begin installing.

I also tried with the official drivers from AMD's website (both Catalyst and Crimson, as I'm not sure if they're the same thing and if I should install both or just one of them) and it was the same story — starts to install, then says We are unable to find a driver for your system. No supported AMD hardware was detected.

Anyway, as I'm now running on the Windows Basic Display Adapter, it makes me think it might not be the display drivers causing the BSOD?

That seems to have done it! Thank you so very much! The bootcampdrivers.com drivers are installed and no BSOD to be seen!

As far as I understand, AppleHFS.sys and AppleMNT.sys are only used for mounting the macOS volume/partition? If that's all, I don't really mind if I can't mount it/see it from Windows.

Is there anything else I would need to have a look at or set up now or is this it and I can just go an use it normally?

Also, can I use the Apple Software Update within Windows or is better not to (in case it tries to reinstall AppleHFS.sys and AppleMNT.sys or something like that)? It just popped up with a Wi-Fi Update for Boot Camp (6.4.0), Boot Camp Update (6.1.9) and Apple Software Update (2.1.4)?

Hi, no, it's a 5.1 (Mid 2010, 2x 2.4 GHz Xeon, 32GB RAM, 250GB SSD (OWC) and ATI Radeon HD 5870).

Not sure if it's relevant, but I did do a firmware upgrade before installing High Sierra.

Will do!

And thanks again for all your help, you've been a lifesaver!
