Initially, I was using Windows 7 home premium. And I decided to switch to Ubuntu 16.04 LTS. After installation, I am unable to see 500GB partition. The partition consists of important files. Below is the result of commands I found on AskUbuntu. Please suggest some solutions ASAP.
sv@sv-Aspire-5755G:~$ sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 698.7G 0 disk

├─sda5 8:5 0 555.1G 0 part /
└─sda6 8:6 0 3.9G 0 part [SWAP]
sr0 11:0 1 1024M 0 rom
sv@sv-Aspire-5755G:~$ sudo mount -t ntfs /dev/sda5 /media/windows
Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.
