GRUB2 not displaying timeout in the OS selection screen at startup

Hello,

I have newly installed Windows7 on the computer with ubuntu installed. Then using the Ubuntu 9.10 live cd I have reinstalled the GRUB 2 and recovered Ubuntu. After that when system starts up and loads Grub 2 the timeout is not displaying. Please tell me the solution. I am able to boot all the submenus option. But I want to boot the default OS automatically and don't want to always press the enter key.

I am attaching my grub.cfg file. I also want to know how to make Windows7 default entry in the boot order menu. Please help me soon.
