Last time I used this (update-grub on fully updated Debian testing) a few weeks back it did nothing for me either, however as a workaround you can re-install/re-configure grub-pc and/or grub-pc-bin (via apt- get, synaptic or your personal favourite installer) and that will install the grub menu for you. I think it was the first of these two options (re-install grub-pc) that did the trick but just in case I remember wrongly, I mention the other software too. However, it probably needs tracking down as to why this no longer works for all, so if you are willing, please continue to work through other processes first.
