MP 7,1 Bootcamp endless boot cycle with Mac Pro 2019

[LeonPro]

Checking if there are any Windows 10 bootcamp users out there that may have experienced and endless boot up cycle trying to boot into Windows 10 with a Mac Pro 2019.

I don't know if it's a drivers issue, but basically I am able to install Windows 10 Pro just fine. Restarting between Catalina 10.15.6 and Bootcamp Windows 10 is no issue. However once I actually shut down the computer and then start into Bootcamp the machine goes into an endless boot cycle with an error message in between. It says it's repairing itself but it never resolves and only goes into an endless boot.

Leon,

There may be a corrupted Windows 10 bluetooth driver. Look here: https://answers.microsoft.com/en-us...rea-bsod/5a224ada-cbce-4178-af88-1118f475cf7a

I DuckDuckGo'd the terms "mac bthport.sys stopcode" after reading the fine print in your screen capture.

Hope this helps.

Since I don't have that problem, I can't be sure...

Tom

Appreciate the assistance. I didn't realise I had a "fine print" on my screen capture on what specifically failed. Hoping that narrows down how I can solve it in the future.

I removed and reinstalled Windows 10 under Bootcamp for the Nth time (countless times at this point). And will slowly start loading drivers back in to narrow and see which failed.

I'm talking out loud at this point in case something sticks for other people:

- My only Bluetooth peripherals are the Apple Magic Mouse and Magic Trackpad.

- Other peripherals I've connected after are:
Razer Nari Ultimate Headset with 2.4GHz USB dongle
Razer Viper mouse
Corsair K70 MKII SE keyboard

- Only app I've installed (and the reason for booting into Windows 10 when not working into Mac OS:
Steam app with CSGO

Prior, I've installed the Razer and Corsair apps to customize but this last round I have not installed anything. In fact I've disconnected both Razer products and started with only the Corsair keyboard.

Will go from there.

UPDATE: Okay so I narrowed it down to the Razer device(s) that I have connected - either the Razer Nari Ultimate headset which operates wirelessly over 2.4GHz or the Razer Synapse 3 software.

After a complete reset of the Bootcamp partition, I slowly installed each device. Boot up between Catalina and Bootcamp. When I don't get a boot error in Windows, I go install the next device.

I now stopped at installing the Razer Synapse 3 software that manages both my Razer Viper mouse and Razer Nari Ultimate wireless gaming headset.

I've been booting between Catalina and Windows 10 Pro since yesterday with no further issues. I decided NOT to attach the Razer Nari Ultimate gaming headset and Razer Synapse 3 software (it tries to auto install itself after detecting the Razer Viper mouse - which I cancel the installation procedure).

One of these two Razer is the offender and I'm guessing it's how the wireless headset despite operating at 2.4GHz is causing havoc with Bluetooth.

I have tried it so many times.With VMWARE Fusion Parallels Desktop. and Rufus when i in-staled Windows Bootcamp on the internal drive, i don,t know whether that was the reason i had problems with the internal Windows bootcamp?I get all that stuff to ,sometimes it says it is trying to repair and trying to diagnosing the problem. I have a 2017 5k IMAC.I also get the same stuff when i got Windows Bootcamp on external drive.i managed to set it all up ,but the next time i just got the same problems i have tried it so many times.With VMWARE Fusion
I don,t understand why Windows bootcamp want work on my 2017 IMAC?

@LeonPro , @Roxy.music do these errors happen before or after you install the BootCamp drivers? Do you know what BootCamp build you're using (should say when downloading in BootCamp Assistant)?

I've had no problems at all so far since installing, but I don't use Bluetooth devices. I recently added a Logitech MX Vertical mouse (USB wireless, 2.5GHz) with no problems.

Okay, I think I found the device that's causing my specific Bluetooth error. I was blaming the various apps as I get the error after installation like I said above.

However, I now narrowed it down to my Macally Solar Wireless Bluetooth Keyboard that I paired, but only use as a spare. Because it's a Mac-only keyboard, the drivers didn't carry over to Bootcamp and Windows didn't know what to do with it.

When I removed the pairing, Windows Bootcamp is now playing fine.

It wasn't obvious to me, but lesson learned. Just because it works under Mac doesn't mean it will carry under Bootcamp.
