Boot error on ubuntu 16.04

How to solve this error
I run fsck /dev/sda1 using live cd
Nothng happen

usually /dev/sda is the whole device, and /dev/sda1, /dev/sda2 … are partitions which may contain filesystem. fsck works with filesystems, so running fsck on /dev/sda is usually meaningless - you will get an error, because there will be no filesystem to check. But sometimes it works (but in that case there will be no /dev/sda1 and other partitions).
