[Bug 339724] Re: Unable to install GRUB in /dev/sda: "Cannot find a GRUB drive for /dev/sda1. Check your device.map."

[Balan Nadaajah]

I have been trying to install Ubuntu 11.10 since one week.  Everytime it
fails in the end with bootloader can be loaded.  That is the grub part.
it is bit frustrating and there is no clear steps to resolve this issue.

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

Status in “ubiquity” package in Ubuntu:
  New

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.
