Hi folks I accidentally changed my password.

and wanted to ask if someone can help me how I can get access again.

Please learn to google…: /

When I press the esc key there's nothing with root but something completely different

Then what is there?

We don't know your screen. How should one help you somehow if you do not provide any information. Why do you use Linux at all when you are generally unable to google small things.

I say yes! I watched tutorials but I see completely different windows.

The only thing that is shown to me or that opens is the boot menu

With shift key?

Yes
