I hope nobodys annoyed by this bump, but I found another good solution after struggling to install Bootcamp on a new SSD on my Mid-2012 non-retina MacBook Pro 15". It's essentially very similar to the one in this thread, but will work without the dependancy on a upload somewhere in the internet.
The reasons for this BSOD are simple: Some Bootcamp support drivers are simply too old for the 1903 update of Windows 10 and cause some kind of hickup, so you need to replace them before they can cause any harm to your system.
The way to solve it:
1. You need to install Windows 10 with all its updates BEFORE you install any Bootcamp drivers.
2. Then install the drivers of your Mac system (brigadier helps with that), but DON'T restart yet. You need to edit two files before that.
3. Head to C:\Windows\System32\drivers. Delete WUDFRd.sys & rename MacHalDriver.sys to MacHalDriver.sys.bak (you might need to allow permission in order to do that, which is its own topic. I might link instructions to that later)
4. Create a shortcut to brigardier, right-click it and edit "destination" like this: "brigadier.exe" --model iMacPro1,1" - This will force brigardier to download more recent drivers that you will need.
5. Run this shortcut, head to the directory where brigardier.exe is in and click through this path: BootCamp-041-55643\BootCamp\Drivers\Apple\AppleHAL.
6. Right click on that "newer" MacHALDriver.inf & install it. Check if this file appears in the System32. folder.
7. Restart & enjoy your system!
Feel free to text me or ask me questions on any of these steps. I struggled for two weeks and finally got it working. At the end, here's some context & insights which might only relate to my MacBook model, but might help you with your Bootcamp issues:
- It's somehow more difficult to install Bootcamp on a SSD
- In case you removed your DVD drive in favor of another HDD (like I did), UNPLUG the HDD drive before erasing your SSD & installing your TimeMachine Backup
- I also updated to macOS Catalina: That's when the Bootcamp assistent worked the best (I unchecked Windows Support software though - it loaded way longer than it should and I was fine with using brigardier for that)
- You should install from a DVD and not from a USB stick. The Win10 installation didn't accept the BC partition for some reason when trying it with a ISO-based USB stick
- ...but if you removed your disc drive and connected it externally via USB, it might still need a stick in order to even start any BC assistent functions. So leave a stick in there, let it install an ISO on it, but don't use it.
- Hook your MacBook to ethernet, since its the only way to update Windows before installing the Bootcamp drivers.
- After you finished all steps, you're free to reconnect your other HDD
surprised to have followed his instructions, rebooted and found that my keyboard is now backlit! and the function keys are working like they should be!!! Thankyou!!
