I was thinking more "navigate to a file" type stuff. Understanding what admin privileges are, copying and pasting, stuff like this.
Often times when I needed to help a non-tech savvy person solve an issue on any OS it is some really dumb problem like them not knowing how to run some program as admin (no idea why they want to run a graph software that needs admin privileges to this day), opening the file manager, navigating to a folder to paste a file to it, or simply reading the popup instead of panicking.
At no point have I said going into a BIOS is basic knowledge. But if the people you're dealing with struggle with the most basic shit ever then you're not even gonna get to the BIOS part, and if they aren't willing to learn how to use a computer then they probably shouldn't use a computer.
