Ubuntu gives message "Welcome to emergency mode !"
The Emergency Mode sometime means that your file system may be corrupted. In such cases, you will be left out with a prompt to go nowhere.
All you have to do is perform a file system check using,
fsck.ext4 /dev/sda3
where sda3 can be your partition and if you are using ext3 file system, change the command as follows:
fsck.ext3 /dev/sda3
About the partition number, Linux shows you the partition before arriving at the prompt.
This should solve the problem.
From my experience, if you have created a new partition or edited existing one, you may get this error. I had the same error some time back. If you happened to be in the the Emergency Mode and see that it cannot load some of your drive. It means that some of your device id have been changed. So, you have to update the id accordingly in /etc/fstab file. Then do the following steps.
- Type your root password
- cat /etc/fstab
- blkid (show the device ids)
- Now check which which UUID in /etc/fstab does not apper in blkid output
- type 'nono /etc/fstab' and Comment out that line (Just put # infront of the line)
- type 'reboot' (Now your problem should be fixed and after logging in successfully, you can add the current UUID in /etc/fstab file )
As an example, this is my output of /etc/fstab file, in which I simply commented out the line ( UUID=C3D1-3CB7 /windows vfat utf8,umask=007,gid=46 0 1), because the UUID=C3D1-3CB7 has been changed.
