My partition mounted at /home keep getting unmounted after every restart. How to stop this?

I have recently started using Ubuntu 16.04 and I made a fresh installation. Whenever I restart my computer the /dev/sda gets unmounted. As a result I can't login through the UI and I have to manually mount my disk and login every single time

Following is the result mount -l command

# /etc/fstab: static file system information. Use 'blkid' to print the universally unique identifier for a device; this may be used with UUID= as a more robust way to name devices that works even if disks are added and removed. See fstab(5). <file system> <mount point> <type> <options> <dump> <pass> / was on /dev/sda5 during installation
UID=5396e03e-8e0a-4845-95da-31290534e988 / ext4 errors=remount-ro 0 1 /home was on /dev/sda6 during installation swap was on /dev/sda2 during installation

Thanks in Advance!

Add your /dev/sda6 to your /etc/fstab and it will be automatically mounted during start up.

Find out your UUID of the partition:sudo blkid /dev/sda6

Then add this line below the
#/home was on /dev/sda6 during installation
UID=inserthereUUID /home ext4 defaults 0 0

you can try if it worked if you unmount it manually and then type in the terminal sudo mount -a if it was mounted correctly it will always be mounted during start up.
