Windows disappear from GRUB after updating to Ubuntu 11.10

Hi folks! My laptop has ubuntu and windows. I just updated my ubuntu from 11.04 to 11.10. I used the updater from ubuntu 11.04. However, after updating Windows XP disappeared from the GRUB list. What should I do to recover the windows option?

Open gnome-terminal and enter this command:
sudo update-grub

I just fixed the problem. I ran bootcfg /rebuild under windows recovery console and then ran update-grub in ubuntu. Then I can see windows option in grub.

Thanks, gordintoronto and darkod!
