How to Fix Raspberry pi's fstab

I was trying to use raspy as a file sharing server in the CIFS-compatible application samba.
Up to that point, the operation was normal operation.
Also, at the point where you set the automatic mounting method at startup ↓

The etx4 part of the fstab file (specifying the Linux file system name behind the mounting destination at the bottom of the UUDI)
I wrote it wrong in ext4.
After that, I couldn't start the raspy, and after that, I rewritten the problem (ext4→etx4), but it still doesn't seem to start.

Please let me know who you are.

By the way, here is the error on the raspies↓↓↓

Also, I tried to mount it from my computer's virtual environment (centOS7), but it's stuck because it looks like the following.

mount point does not exist

Also, since the mtab is broken, I think it can't be mounted, so I would appreciate it if you could fix the mtab.

Please help me.
