I haven't used ubuntu for long time so I forgot most of command and how to fix issues.
I have Dual boot , Windows 8 and ubuntu latest version I use ubuntu for my work and Windows for gaming and other stuff.

Unable to access “Main [G-E]”

Error mounting /dev/sda2 at /media/semary/Main [G-E]: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/semary/Main [G-E]"' 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/sda2': 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 already turn off fast startup on widows 8
