Grub Doesn't show menu

Hi guys.

I have installed Acronis disk director in windows XP and allocate some free space to install Debian beside fedora.
after completion i rebooted and now grub is in command line mode and does not show the menu list.
(I didn't remove the fedora partition. I just allocate some space from windows partitions.

How can i change it to show OS menus.
