After having trouble logging into my computer, I reset my windows 10. However, I still can't log in and now the shutdown/restart button from the login window has disappeared.
Following is the image i found online, as you can see there is a button on the bottom right corner of the screen which I am missing. The Utility Manager button also does not do anything when I click on it. I can't reset the pc again either, it says it is locked.

Anyway I can just remove windows 10 and reinstall windows 7 without losing my personal files? Thnx.
