  • @harry -- see if the linked 'possible duplicate' helps. Are you able to make a LiveCD with a different computer?

  • harry, it's quite possible to recover this. This happens to Wubi installs where the root.disk is corrupted or missing. You can find more discussion here: askubuntu.com/questions/85268/grub-booting-problem (I mentioned this before but my comment was deleted).

    These commands are incorrect for installing grub from a live CD. Also since this is a wubi install, it will stop the computer from booting. I can only -1 once though ;)
