How do I get Boot Camp back as default startup volume? I used to have Boot Camp as my default startup volume. 

I have updated to 10.14.4 recently and since then Boot Camp is no longer shown under start volumes. My MacBook Pro boots to macOS now. 

I can boot to Windows using the Alt key, but this is not what I want.

Is there any way to change it back to Boot Camp?
I just noticed that it was not only an update of macOS, but I had also NTFS for Mac installed. This prevents the Boot Camp partition to be used as a startup volume. If you deactivate the NTFS driver in NTFS for Mac, it can be used as startup volume again.
