Windows setup post (multi boot) install. What if anything is there to configure?

I have Catalina & Windows 10 installed and running on separate SSDs. What do I need to do to setup windows post install? I just left Windows running unattended and when I returned after an hour it woke up to the open core boot loader.

Were you able to boot Win10 from OC?
