I am using ubuntu 14.04 Lts. And i have administrative access.
I have failed to mount the disk drivers automatically. It says
Error mounting system-managed device /dev/sda7: Command-line `mount "/mnt/D6EEAF55EEAF2D25"' 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/sda7': 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.
I have used the disk drivers option to mount it. But It gives error on startup and ask S for skip and M for manual mounting.
[i have installed windows 8 and ubuntu in different drive.]
I have Found the solution. It is due to the windows 8 fast boot up feature. I have just disabled the fast boot option in windows 8 and it worked for me.
Here you can get how to disable fast boot feature in windows 8. enter link description here
