Fix Windows 8 (Dual Boot) NTFS Partition Mount Failure In Ubuntu

Below is error message viewed when you try mounting NTFS partitions:

Error mounting /dev/sda3 at /media/elliot/Data: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda3" "/media/elliot/Data"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0).

Metadata kept in Windows cache, refused to mount.

Failed to mount '/dev/sda3': Operation not permitted
The NTFS partition is in an unsafe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.

Reasons

After series of searches, reasons for this were

1. Windows didn’t shutdown properly or has been hibernated.

2. Fast start up has been enabled in Windows 8 (this is by default)

Solutions

1. Reboot Windows and then boot into Ubuntu.

2. Disable fast start up in Windows 8, by navigating to Control Panel –> Hardware and Sound –> Power Options –> System Setting –> Select What the power buttons does and un-check the Turn on fast startup.

You should be able to access you NTFS partitions now.
