I cannot boot into Windows, see point 4. But thanks anyway - might fix the problem if I would be able to boot into Windows.

Just keep doing what you have been doing as far!

Installs mint. Connects to wifi at work. Prompted with a window that wants me to specify certificate versions or whatever. No clue about what any of it means and never get to connect. Uninstalled and back to Windows. Mint so easy to use /s 👍

Well, only way to solve this is by having people here who aren't idiots (whatever that means to you) to participate and make things better. But this is too hard for most people, I guess.
