Dual boot Ubuntu/Windows emergency mode

Almost every time I try to boot Ubuntu I get emergency mode screen as seen here:

I tried all options listed and nothing helps. After randomly many reboot and/or force shutdown I manage to boot Ubuntu. How can I solve this?

My fstab looks like this:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=73afa7f9-6262-495e-b6a3-deda059da829 /               ext4    errors=remount-ro 0       1
# /home was on /dev/sda5 during installation
UUID=68294dbf-0922-49bb-9cf6-2b1fd89b45f8 /home           ext4    defaults        0       2
# swap was on /dev/sda6 during installation

I am currently running 17.04. but had same problem in older versions.

The results of fdisk -l are:
