Windows7 not showing in the boot menu after installing ubuntu along side windows 7

Hi , I am using Inspiron N5110 laptop. Recently i  have installed Ubuntu alongside Windows7 on my laptop by creating a  new partition. However after i reboot my machine, in the boot menu i could see only ubuntu related OS. I am unable to see Windows 7 in the menu for selection. Please can you let me know any solution for this. Thanks, Sridhar

It sounds like during the install of Ubuntu, you wiped out Windows 7.
