Title:
  Ubuntu dual boot failed due to failure of "grub-install"

Status in grub-installer package in Ubuntu:
  Confirmed

Bug description:
  I had a working Ubuntu 14.04 and Windows 8.1 dual boot system on
  Lenovo Ideapad P500 touch.

  After upgrading to Windows 10, grub had issues identifying correct
  boot partition. I tried to re-install grub but it failed. I couldn't
  restore Ubuntu 14.04 ever since.

  I am now trying to upgrade to Ubuntu 16.04 LTS or even a fresh start
  will be ok. but installation fails due to failure of "grub-install"
