My PC just stopped and displayed "The current bios setting do not fully support the boot device"

I walked away for 5 minutes and when I came back, that was displayed on the screen. So I found a YT video that suggested enabling CSM in the bios, which I did and rebooted.

I then saw this:



So I manually powered the pc off and on and it's back in Windows. What is going on and should I be proactive in fixing something?

As you haven't listed any of your PC's specs, it's impossible to guess whether CSM is relevant to you.

As you say that you're running Windows 10, it's possible that your hardware is old, which could mean that it should be enabled. But if the machine booted OK before. that's unlikely.

If you need specific Windows 10 help, there are similar forums for that. Ten Forums - Windows 10 Help and Support Forum

Set your BIOS to defaults again. Did you make any changes to it?
