[Bug 995229] Re: grub-installer refuses installation to media that previously held a hybrid image

[LeoRochael]

** Description changed:

  While installing Precise to a USB media that previously held an
  isohybrid image, installation fails with error message:
  
  /usr/sbin/grub-setup: error: hd2 appears to contain a iso9660 filesystem
  which isn't known to reserve space for DOS-style boot.  Installing GRUB
  there could result in FILESYSTEM DESTRUCTION if valuable data is
  overwritten by grub-setup (--skip-fs-probe disables this check, use at
  your own risk).
  
- The error I got exactly as described here:
