  • I would boot from a live CD and backup your important data. Then, check your HDD for errors, check the SMART data. Then, download the boot-repair CD, boot from that and see if it fixes your boot issues. (Not holding my breath but worth a go). Failing that I personally would re-install. – hatterman Dec 27 '16 at 18:47

Lets check the file system to make sure there aren't any errors.

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery Mode
  • choose root access
  • type sudo fsck -f /
  • run fsck more than once if there were errors
  • type reboot

To check the hard disk for hardware errors...

  • boot the Ubuntu Live DVD
  • choose Try Ubuntu
  • start the Disks application from the Unity dashboard
  • click on the "hamburger" icon in the top-right corner of the Disks window and select SMART Data & Tests
  • review the data, and run the tests
  • if you get/see errors, you may have a hard disk problem

If this doesn't help, you're going to need to reinstall Ubuntu. Boot the Ubuntu Live DVD and choose Install Ubuntu. Choose reinstall, and make sure to uncheck the format partition selection, and it'll keep your existing /home directory.
