Linux Blank Screen While Opening (Manual fsck Required)

• If you faced with the problem of Manual fsck Required and see a blank screen.
• The root filesystem on /dev/$part requires a manual fsck where $part is the problemetic part of the disk in the system.

# from there, you should be able to drop to some maintenance shell (if not already opened)
fsck -yf /dev/$part
#if there are any errors rerun the command above

# login as usual
exit
# and proceed normally
