Laptop shows strange sign?

My laptop was off and immediately after switching on this sign came up (see photo). I pressed "no" and then it went off. Then he switched on normally. I didn't do anything before, just used it normally. (Youtube, Wikipedia etc) … What could that have meant?

Hmm… Sounds like a virus, I would say, as long as you have not started the recovery mode manually, which can also be canceled by pressing the "no" button

It's not just a virus… Just came across a key or the device didn't turn off properly. That is enough.

Just came across a button or did not turn the device off properly. Half as wild. So he just wanted to fix your record.

I would press yes because they ask you if you are sure you want to go back.

But that doesn't look like repair mode to me, but rather like system recovery… If he presses YES here, his system should probably be flattened and assume the delivery status. Whether he wants that…

No it does not.

https://www.google.com/...overy.html I think with the disks it is data recovery. There are always different definitions. For some it's factory reset for others it's data recovery.

No way!

OK
