[Bug 1140414] Re: GRUB needing to be continuously reinstalled

[Michael Blackburn]

I uninstalled the program which supposedly manages the cache features.
The drive is also formatted into ext4 and is not visible unless you go
into Device Manager.  I am not sure how to be more sure windows is not
interacting with the drive.  I have also noticed that when I am unable
to boot GRUB from the cache drive I am also unable to boot GRUB from my
USB stick Ubuntu 12.10 install.

sudo dmraid -s -> "no raid disks"

I have just reinstalled GRUB again and will run that script if/when the
problem happens again.

Title:
  GRUB needing to be continuously reinstalled

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo T430s laptop with a dual Windows/Ubuntu Install.

  Windows 7 Pro 64bit is installed on the laptop's main hard drive
  (default from the manufacturer)

  I also have Ubuntu 12.10 64bit installed on the laptop's internal 16
  gb cache drive. The original function was to be a cache drive for
  windows but since Lenovo did not set it up properly I decided to try
  running an Ubuntu install off of it (works wonderfully, when I can get
  it to boot!).  This drive is a select-able boot option when choosing a
  device to boot from before the computer starts up.

  The problem: I have had to reinstall GRUB on the drive multiple times
  using an Ubuntu Install DVD (with boot repair).  Seemingly at random
  intervals GRUB will not launch when I select the bootable cache drive
  and I need to reinstall it with the DVD, then it will work fine for
  several boots until GRUB dissapears again.  I have only been
  installing GRUB on the drive with Ubuntu on it as I like the ability
  to turn the laptop on and have it automatically boot into Windows
  without launching GRUB.  If installing GRUB on the main drive is the
  only solution then I will do that but I am wondering if there is
  another problem happening here.

  Thanks for the help
