with BIOS boot disk selection.

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.
