Emergency mode screen problem!

Hello, I wasn’t able to make any thing at one of my partitions like deleting, coping, cutting or even moving files so I tried this solution in the picture below that caused the emergency mode problem I tried many times to boot in my ubuntu 16.04 and the emergency mode screen appears to me and I can’t login the system because of this screen.
please note that I have windows 10 beside ubuntu 16.04.
