Public bug reported:
Dual boot Ubuntu 12.04 / Win7 SP1 Dell Optiplex 990 computer. The
following problem is repeatable every time and occurs on multiple
machines. When running update-grub the terminal displays:
dtc-admin@DTC141:~$ sudo update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.2.0-23-generic

done
update-grub doees not generate entries for the win7 partition so the system can
no longer be booted into that OS.
