Comment 4 for bug 426061

Since my previous post above, i've rebooted & grub2 menu do not show me all the distro. Strange because i've ran grub-mkconfig & it was complete, but seem that it has not been saved.

So, i run again :
sudo os-prober : still don't find all the distro
sudo update-grub2 : nothing added
sudo grub-mkconfig : everything is found

run again:
sudo update-grub2

and reboot

Good, grub menu is now complete & it boot fine.

So, there is still something wrong about os-prober.

All this on Karmic 32 with the latest upgrades.
