BootCamp fails to start after upgrade to MacOS Sierra 10.12.1

I have seen similar behavior on my mid-2016 retina MacBook. I no longer have functioning Bluetooth.

I know how to fix this but you will use with out Bluetooth
first open your BOOT CAMP setup file
delete setup file Bluetooth
And setup agian BOOTCAMP, you can pass the blue srceen and use normal
Enjoy you MacBook <3

this works for me (disabling the serial UART host controller) in 1511 but problems started when windows 10 tried to update itself to 1607 (anniversary update), the bluescreens appear mid-way thru the update. For Now I'll click defer upgrades in WIndows 1511 build.

Apple, pls patch macOS sierra 12.1 asap!!

my guess is that until apple fixes this, no one will be able to install or upgrade Windows 10 as the setup process will re-discover the disabled bluetooth device.

I have the exact same problem (MacBook 12" Early 2015).

I am planning to reinstall Windows 10 after Apple has fixed this issue. How do I know if Apple has fixed this?

Dear jspegs,

You did a great job, you've test the 10.12.2 beta that let us know the first beta still not fix the Boot Camp bugs. You save me time because I've registered as beta tester but didn't have time to test this beta patch.

Do you mind keep testing the next couple beta patches and update us the results?

Appreciate on your great help.

Anyone know if Apple has officially acknowledged this issue? Pretty insane that it's still an issue and no clear fix other than downgrading. Anyone checked in Beta 3 of 10.12.2?

Wow, this worked for me on my 2015 macbook, thanks. I had to reboot lots of times using an externally connected USB keyboard to be able to choose safe mode in Windows 10. I could not disable the device directly in safe mode, but instead uninstalled the driver, rebooted normally into Windows 10, and from there disabled the device completely.

Apple needs to address this ASAP.

I have macbook 2015 12 inch same problem - disable buetooth solve this. But where can i find information wheter Apple fix this ? Because i have second macbook and i want know when i can update to The latest Sierra (now have el capitan)

Run Apple Software Update on the Windows side to check.

Stay with El Capitan, otherwise you will end up this problem on a second Mac.

same issue here. it all started when my windows 10 couldn't boot showing a BSOD generating an error with ACPI.sys

So i thought it was windows and a went for a clean install through bootcamp. the thing happened again once i tried to install the apple drivers (previously downloaded by bootcamp itself).

APPLE please do something or we can't use windows.

You don't have to reinstall windows. As workaround described in detail in this thread start windows in safe mode and disable the UART enumerator in the Device Manager.

Running a Macbook 12" 2015

MacOS Sierra 10.12.1

Still Stick in an endless loop

Cannot get SafeMode prompt anymore even with a USB Keyboard

Windows Partition has been set as default Boot Disk in OSX

Hi

I seemed to be lucky to have enabled F8 in my previous windows 10 installation. Just read that F8 is disabled by default in Windows 10 (UEFI + SSD) to make the boot process faster :-(

After the BSOD is there the option to restart. Seems that pressing Shift while selecting Restart enters safe mode as well. RobjDerby: Would you please try if this is working.

unfortunately Windows 10 doesn't allow to enter "safe mode" and it just keeps rebooting.

the faulty driver is the Bluetooth one.

If you finally go for a new Windows installation, when you install the bootcamp drivers, you will experience the same issue, so the workaround is to delete the following folders under the WindowsSupport folder and run the installer again:

\WindowsSupport\AppleBluetoothBroadcom64

\WindowsSupport\BootCamp\Drivers\Broadcom

it worked for me after on a new Windows installation. of course the Bluetooth doesn't work.
