[Bug 487689] Re: Ubuntu Server 9.10 (karmic): grub2: error: invalid magic number

Karmic reached end of life some time ago, are you able to reproduce this
on a currently supported release?

Title:
  Ubuntu Server 9.10 (karmic): grub2: error: invalid magic number

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub

  I installed Ubuntu Server 9.10 (karmic) using text-based installer
  into a KVM VM.  During installation I provided console args after
  "quiet splash" so that a serial console would work.  After
  installation the hypervisor reboots the VM and reconnects me to domain
  console.  There is no console output.

  I boot the VM using the 9.10 iso file and enter rescue mode.  The
  kernel args are fine in grub.cfg but upstart is not configured for a
  serial console so I configure one.  Create a /etc/default/grub file
  with serial console definitions. Do a 'update-grub' and a 'grub-
  install /dev/sda' and exit.  set hd as boot dev and reboot.  The
  serial console now works but I'm getting this message on console:

  error: invalid magic number

    Failed to boot default entries.

  Press any key to continue...

  
  Something is obviously wrong with grub2.  Is there any workaround to get this system booting?
