Title:
  grub-install returns "1: /usr/sbin/grub-install: sed: not found" error

Status in Boot-Repair:
  Triaged
Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  The original problem was that Ubuntu would not launch on my dual boot
  machine.  I got errors like: "failed command: read DMA EXT" and
  "status DRDY ERR" and "error UNC."  Messages that made me wonder about
  hard drive failure.  However, after I ran boot-repair (from an Ubuntu
  12.04 live CD) and it failed, I lost my boot screen and couldn't get
  into Ubuntu or Windows.  All the disk scans I ran showed no hard drive
  problems..  I got failure messages during the boot repair.  Here is
  the report from the repair: http://paste.ubuntu.com/1019494/
