After the update I have absolutely no problem with Linux, but Grub doesn't let me start Windows any more. (Entry is there but I only get the flashing hyphen and nothing else happens)
Can I safely run "update grub" without damage to the Ubuntu installation?
sudo update-grub will do the job I guess. :) (In a nutshell, yes you can. >.>)
Corrected the 'update grub' line in my answer ... thanks Quack.
2, sudo update-grub will do fine. all this does is regenerate the /boot/grub/grub.cfg

grub-mkconfig -o /boot/grub/grub.cfg "$@" -- can you guess what update-grub2 execs? update-grub "$@" !! so yeah, no need for the 2.

You have been hit by Bug #570765 , which is quite common for 10.04 adopters running Windows.
Loading the latest updates and rebooting will fix it.
