My Boot Runner dual boot worked fine for a long time, but I can no longer boot to Windows 10. My OSX boot disc is an external SSD:

And my Windows boot is on a seperate SSD. Here is the Disk Utility report from the OSX boot:

Any idea why it has ceased to work?
Do I need to provide additional information?
Is it possible that SIP is no longer partially enabled? What do you get when you run “csrutil status” in Terminal?

System Integrity Protection status: disabled.

??? Any ideas? Additional information needed?
I realize that I can go into System Settings and permanently change the boot drive to Win 10 (my Os’s are on two seperate SSD’s). I do not, however, know how to change it back once (or if) I am able to boot from my Win 10 drive. I’m not quite ready to dump OSX - but I am getting close!
You can always hold the option key down when the Mac is starting up and choose either Windows or macOS.

The option key held down on reboot did not work. OSX starts via Bootrunner.
When you hold down option on startup, it should show least the MacOS volume. Does it show that?
tim
I have a mid-2010 Mac Pro. It works fine, but Apple no longer supports OS upgrades on it. So I’m dumping OSX and I’ll make this a pure Windows machine. It’s funny that Microsoft provides better legacy support for legacy Apple hardware than does Apple.
