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

Question

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

# /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).

 /home was on /dev/sda6 during installation

Thanks in Advance!

Solution

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.

Can you post your /etc/fstab?

Well you see that your home is not listed as a mountpoint in fstab, if you add it in the file it will be mounted automatically during boot.
