[Bug 1709336] Re: ubuntu 16 Grub2 fails to install dual boot windows 10

[Phillip Susi]

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

Title:
  ubuntu 16 Grub2 fails  to install dual boot windows 10

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Trying to install Ubuntu 16 or 17 on a Dell Inspiron 7640 with a pre
  installed Windows 10. Dual boot.

  I'm using a gpt/uefi pen drive. Notebook setup with uefi and secure
  mode on. Fast start disabled.

  Tried everything: automatic installation side by side, advanced
  installation with boot in the efi partition (Windows), versions 17 and
  16, network connection on and off. It always abort installation at the
  same point: grub2.

  Thanks!
