MP 7,1 Bootcamp safe mode: black screen

[jaapaap79]

Stupidly I tried installing bootcampdrivers blue using the Setup in the zip file with everything set to default.

Now I can no longer boot into Windows 10 and I just get a black screen after the Windows logo is shown briefly, presumably because it doesn’t have the graphics card driver anymore.

I tried removing the MPX module and a regular RX580 card instead but that doesn’t even display the Windows logo.

Does anyone have any ideas what else I might try to get things to boot again and reinstall the regular bootcamp drivers?

Normally safe mode should do. Have you tried it?

Switch display type cables. For some reason, safe mode in bootcamp only functions with HDMI not Displayport or thunderbolt.

Thanks, both. I feel like I’m further from a solution now. I’ve reset the NVRAM and booted in my MacOS which worked fine, but since my Bootcamp has Bitlocker I can’t select to boot back into it. Not sure how to proceed here. Will I have to reinstall both and lose my Windows data?

If you try booting to Windows more than 3 times unsuccessfully it will take you to safe mode selection. If you select safe mode boot you can reinstall the drivers.
