I'm working on both Ubuntu 17.10 and Windows 10 as a dual boot system. Suddenly today I restarted PC from Windows and tried to logged into Ubuntu and then I got stuck at emergency mode. Now I can't get pass the emergency mode. This is what I get and I'm stuck in this screen

You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or D to boot into default mode.
Press Enter for maintenance

When I try to exit by pressing ctrl+D I it loads until 4.9% and redirected to this same screen. So I can't get pass trying to boot into default mode.

I checked and followed this askubuntu question by unmounting and running fsck -y for root directory with Ubuntu live cd. I don't think this is windows stutdown issue as I have been using the dual boot system for quite some time.

So, how can I get pass this and work on Ubuntu ? Any help would be appreciated.

  • Is there anything interesting in journalctl -xb? – Jos Feb 27 '18 at 12:11

Usually one of your file systems is faulty and needs check, a good practice before anything is to check all your file systems:

sudo fsck -y /dev/sda2

sudo fsck -y /dev/sda3


and so on.
