[Bug 1707498] Re: Installation failed: unable to install grub in /dev/sda

[Phillip Susi]

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

Title:
  Installation failed:  unable to install grub in /dev/sda

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  New laptop with Windows 10 preinstalled.  I created a partition and
  installed Ubuntu 16.04 as dual-boot which worked, until Windows 10 ran
  some updates and I lost the boot menu.  So I cleared the partition,
  and now every time I try to reinstall Ubuntu desktop it fails when
  trying to create the GRUB menu and I can not continue.
