Title:
  'grub-install --force "(hd0)"' fails on trusty during installation

Status in “grub-installer” package in Ubuntu:
  Fix Committed

Bug description:
  Network/PXE installs of Trusty fail on installing grub.

  The error message in syslog is:

  Installing grub on '(hd0)'
  Running chroot /target grub-install --force "(hd0)"
  Installing for i386-pc platform
  grub-install: error: disk `hd0' not found
  error: Running 'grub-install --force ''(hd0)''' failed.

  The workaround is the following

  chroot target
  echo "(hd0) /dev/sda" > /boot/grub/device.map

  Then prompting the installer to try installing again.
