[Bug 1697586] Re: grub-install failed on /sda.

[Phillip Susi]

Your EFI system partition is corrupt; you will need to repair it with
either dosfsck or Windows' chkdsk/scandisk.

Title:
  grub-install failed on /sda.

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Forgot the command line.  Have windows 10 preinstalled and am trying to install Ubuntu 16.04 alongside in multiboot.  17.04 beta sort of worked.  It was great until I chose Windows 10 boot manager, then I lost the capability to boot into unbuntu.  The partitions were found on install of 16.04.
  Anyway, sorry, there was a grub-install error on the hard drive.
