After trying out a number of backup solutions with the entire household in mind, and where we need the least complex user interface possible, I ended up going with EaseUS To Do Backup.
One of my machines already had Macrium Reflect installed, and when I did that I elected to install the feature that prompts you at boot time as to whether you want to boot Windows 10 or go directly into Macrium Recovery (which is a really nice option I wish that others offered). I expected that this would be backed out as a part of the uninstall, but it was not.
If anyone happens to know off the top of their head how I might fix this, please share. I thought I'd ask here before beginning to do web searches and/or slog through Macrium's support pages or user forums.
