Can’t Mount NTFS drive “The disk contains an unclean file system” Well, it can be the most annoying error while using Ubuntu in dual boot mode with Windows.
This could be caused by a faulty hard drive, a bad sector on the disk, or a number of other computer problems. As an example, I have had the error after a sudden shutdown and before restarting the computer.
If you getting this error while accessing disk drives in Ubuntu 16.04 you can fix it very easily.
Unclean file system
All you need it to log off the Ubuntu and boot from the Windows.
Now shut down the Windows using Command Prompt with the following command:
Now boot into Ubuntu. The error must be gone.
