[Bug 1053793] Re: warning: this LDM has no Embedding Partition; embedding won't be possible

I cannot get dual boot running with ubuntu 12.10 and windows 7. I spent
a lot of time trying to get it work, without success. With boot repair,
I get either windows 7 running by repairing MBR, or ubuntu 12.10 by
reinstalling grub. But I cannot start windows 7 after grub install, I
get always "Invalid Signature".

Boot repair: http://paste.ubuntu.com/1311856/

I get also this warning:
grub-pc (2.00-7ubuntu11) wird eingerichtet ...
Creating config file /etc/default/grub with new version
/usr/sbin/grub-bios-setup: Warnung: Dieses LDM hat keine Einbettungspartition, Einbettung würde unmöglich sein.
/usr/sbin/grub-bios-setup: Warnung: Einbettung ist nicht möglich. GRUB kann in dieser Konfiguration nur mittels Blocklisten installiert werden. Blocklisten sind allerdings UNZUVERLÄSSIG und deren Verwendung wird daher nicht empfohlen..

Also compared to grub 1.99, the win7 partition needs to be be mounted in
order for grub 2 os-prober to detect it. update-grub does not detect
win7 when partition is not mounted, this was different with 1.99.

Also update-grub always produces an error:
Linux-Abbild gefunden: /boot/vmlinuz-3.5.0-17-generic
initrd-Abbild gefunden: /boot/initrd.img-3.5.0-17-generic
Windows 7 (loader) auf /dev/sda1 gefunden
/usr/sbin/grub-probe: Fehler: Unbekanntes Dateisystem. (Error: Unknown Filesystem)

Can you please tell me how to downgrade to grub 1.99 on ubuntu 12.10?

Title:
  warning: this LDM has no Embedding Partition; embedding won't be
  possible

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Since grub 2.00-4ubuntu1 I've been getting:

  /usr/sbin/grub-bios-setup: warning: this LDM has no Embedding Partition; embedding won't be possible.
  /usr/sbin/grub-bios-setup: error: embedding is not possible, but this is required for RAID and LVM install.

  when trying to update grub, which results in an unbootable system,
  which I've worked around by downgrading to grub 1.99-22ubuntu2 and
  running grub-install /dev/sda

  This system is a self-build that has never had windows on it.

  $ fdisk -l

  Disk /dev/sda: 300.1 GB, 300069052416 bytes
  255 heads, 63 sectors/track, 36481 cylinders, total 586072368 sectors
  Units = sectors of 1 * 512 = 512 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disk identifier: 0x8f83bc52

     Device Boot Start End Blocks Id System

  As suggested, attached are dumps of the first and last megabytes of
  /dev/sda
