Public bug reported:
New, clean install of x86 11.10 Desktop from CD with network upgrade.

tried the workaround @
http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:search
Commenting out three lines in /usr/lib/grub/grub-mkconfig_lib (Step 4)
This bricked grub2, booting 11.10 gets "error: no such partition"
and booting Windows gets: "error: invalid signature"
Undoing the changes (using chroot and the LiveCD) and rerunnin update-
grub restored the original grub boot process.
