> 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.

Please create a new bug report for this (and indicate the report link
here, so that we can follow-up).


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

I think BURG is based on 1.99 so it may help: https://help.ubuntu.com/community/Burg
Else, you may be able to workaround this bug by installing GRUB-Legacy (Boot-Repair --> Advanced options --> GRUB options --> tick GRUB Legacy --> Apply)

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
  /dev/sda1 562628430 586067264 11719417+ 82 Linux swap / Solaris
  /dev/sda2 * 63 562628429 281314183+ 83 Linux

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