Bootcamp - can't boot into windows safe mode

Hi,

I'm trying to boot into windows safe mode so that I can run the DDU utility and install the Bootcamp adrenalin drivers (for gaming). When I boot and select the windows partition, I hold 'shift' which brings up the boot options, I select 4 (safe mode), and the login screen flickers, then a black screen, and no response.

Anyone got any advice (MAC PRO 2019) - I've tried booting from USB and I get thrown into booting in Apple safe mode/target disc mode.

Thanks,

:-)

Mac Pro, macOS 11.2

Hi,

Thanks for your help however no method appears to work - I've tried everything and cannot get into safe mode. Could it be that Bootcamp & the T2 chip doesn't like Windows safe mode? Possibly.

I removed the graphic drivers via DDU app (not in safe mode & rebooted).

I rebooted to a black screen using a 5K monitor over USB-C / Thunderbolt. So, I hooked up a 4K screen over HDMI which did the trick. Windows doesn't play nice with 5K screens over USB-C / Thunderbolt.

Apple T2 has Startup Security. See About Startup Security Utility - Apple Support for reference.

There are several methods to boot in Safe Mode. See https://support.microsoft.com/en-us/windows/start-your-pc-in-safe-mode-in-windows-10-92c27cff-db89-8644-1ce4-b3e5e56fe234 for reference.
