Kali Linux Gets Stuck while booting

Good day guys. Please can anyone tell me how to resolve my Kali Linux 2016.2 boot problem? I was using the system and copied a video from my external hard drive to the system and the system froze after the cooking was complete and external HD was uncounted. I did a hard reboot, ever since the booting stops and give an error message " Failed to start anonymizing overlay networks." And that's where it stops. I tried recovery mode and tried to use system maintenance but still doesn't work.
