I'm unable to restart Windows, it throws up an error. So I got to use Ubuntu and yet I am unable to mount the volume. It throws up the following error:
Error mounting /dev/sda3 at /media/ubuntu/OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=999,gid=999,dmask=0077,fmask=0177" "/dev/sda3" "/media/ubuntu/OS"' exited with non-zero exit status 14: Windows is hibernated, 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.
