[Bug 1400421] Re: grub installation failure

[Phillip Susi]

Your EFI system partition appears to be corrupt.  Please run chkdsk on
it from windows, or run sudo dosfsck /dev/sda2 in Ubuntu to check and
repair it.

Title:
  grub installation failure

Status in grub-installer package in Ubuntu:
  Incomplete

Bug description:
  On trying to install ubuntu in my Lenovo z50-70 laptop (i5 processor,
  8Gb RAM, 1 TB HDD) preloaded with windows 8.1, I get a grub-installer
  failure. I have created separate partitions for ubuntu installation
  (three partitons for /, /home and /swap) using the windows disk
  managment tool. The computer has  a UEFI partition with windows
  bootloader and I am trying to install ubuntu 14.10 using USB flash
  (the boot device is set to /dev/sda). The computer boots into windows
  without a problem.
