Title:
  Unable to install GRUB in /dev/sda: "Cannot find a GRUB drive for
  /dev/sda1.  Check your device.map."

Status in “grub” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: ubiquity

  Ubuntu-version: 9.04 Jaunty AMD64 ALPHA 5, running from live-CD.

  Trying to install to an USB flash stick (4GB) as a normal drive (not
  the USB-live-disk option), with ext4 and boot loader (?) checked to
  install to /dev/sda, not /dev/hd (!). There are no other harddisks
  present in the system, I have not select to create a swap as I've 4GB
  of RAM.

  At 94% / 95% completion, I get a GUI popup:

     Unable to install GRUB in /dev/sda

     Executing 'grub-install /dev/sda' failed.

     This is a fatal error.

  AFTER that: "ubiquity crashed with InstallStepError in
  configure_bootloader()", which is probably a result, not the cause, so
  something else than
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/260001

  I would expect to after installing the OS to /dev/sda, installing GRUB
  should work too.
