description |
This happened after an update to grub using Ubuntu 12.10, all the sudden one day after updating windows 7 would not boot, i noticed that GRUB has now added LDM parameters to the Windows 7 loader in GRUB. Windows 7 is in fact NOT installed on LDM. |
GRUB recognizes stale LDM headers left on the disk after reformatting without LDM. This causes grub to complain either that embedding is not possible, and/or to incorrectly use the ldm partition module instead of msdos. |

WORKAROUND:
Use Boot-Repair ( https://help.ubuntu.com/community/Boot-Repair ) from liveCD to replace GRUB2 by GRUB Legacy: run Boot-Repair --> Advanced options --> GRUB options tab --> tick "GRUB Legacy" --> Apply |

******************** |
[Impact]
Grub can no longer boot Windows
[Test Case]
Use Windows to format a dynamic disk. Use fdisk to repartition the disk as a regular MBR disk. os-prober still recognizes the defunct ldm partition table with the Windows partition in it.
[Regression Potential]
Previously grub had no support for ldm, so the worst case is that it goes back to not recognizing ldm, as opposed to the goal of this patch of only recognizing *valid* ldm.
