Gentleperson, stop doing anything until you know what you are doing!
No, I actually mean that politely. I didn't intend for it to sting.
In the space of a few minutes you have made things considerably worse than when you started, because you didn't understand what had happened and you grabbed for the "okay, time to re-install Windows!" knee-jerk response.
This .. isn't .. Windows.
What you need to do next
is to carefully observe what the system does, or tries to do, when you boot up. Write down exactly what you see and post it here.
