Now my other pc also works.
I copied the menuentry from grub.cfg for sda5 into /etc/grub.d/40_custom and
ran "sudo update-grub" - it never showed sda5 in the output from the command,
but showed the other OS
The setup is:
sda1 windows xp
sda2 ubuntu 8.04 (grub legacy)
sda5/6 ubuntu 9.10 encrypted (grub2)
sda7 debian 5.03 lenny (grub legacy)
sda8 ubuntu 9.10 encrypted (grub2 - active grub.cfg
