I am getting black screen after i run the command fsck.ext4 -vf /dev/mapper/federa-root in emergency mode

   Hi @pscoder.  During boot of your machine, hold the Esc key to access GRUB menu.

and remove the word quiet, then press Ctrl X.

PS:  Is the file system was unmounted when you’d ran this command (i’m sorry, just want to know about these things)?
