How to access windows files in Ubuntu

I am running Ubuntu 14.04 on LEGACY and Windows 8.1 on UEFI . I have my media ( movie songs and video songs) in "MY MUSIC" and "MY VIDEOS" folders in windows.

I am able to access different hard drives except C drive ( windows ). Now can someone please tell me how to access those "my music" and "my videos" folders in UBUNTU? because i cant find them in ubuntu.

Output of lsblk:

Run the below commands on terminal to mount your 240 GB /dev/sda5 partition.

sudo mkdir /media/windows
sudo mount /dev/sda5 /media/windows

Now your /dev/sda5 partition will be mounted inside /media/windows folder.You can browse for the files inside /media/windows through nautilus.
