Hi,
So I'm stuck with this problem and I don't know a way out...
When I recovered a Toshiba satalite laptop FORM windows 10 to 8.1 it crashed. So that probably means that all the files are gone... But that's not even the biggest problem. The screen of the laptop was broken and I used an secondary screen. With the update everything was okay, but when this happened my secondary screen also didn't work anymore! Probably because there ain't no driver installed right now, or is it something else?

So my question is: How can I make the secondary screen work, to install windows again, or do a factoryreset at the beginning? Or is this unhelpable?

THANK you!
LukaHow EXACTLY did you run this Recovery ? ?In the settings of windows.Thats less info than i asked for...there's a few recovery options in Windows....which one exactly did you run ? ?I went left down at the windows button and went to settings, I opened "Update & Security", went to "recovery" and hitted "Go back to a pervious version of Windows.

It worked but halfway it crashed. Now my second screen doesn't work anymore so I can't SEE whats going on

Thanks already for helping!
