That put it in some limbo state that in the past I've had to use recovery media or if lucky the onboard recovery to recover.
HOWEVER that does wipe out apps and files. If you didn't backup your stuff you stop and recover files first.
i was updating my windows 7 to 10. it was updating smoothly but then my father(being the hero that he is) hard reset the laptop and now my laptop is stuck, it goes to the booting menu. then the "windows error recovery" screen, and when i choose "start windows normally" it shows the logo and says "starting windows" and then it just restarts. how do i solve this? this loop has been going on for the last 2 hours.
