How to boot ubuntu on start up?

I installed ubuntu on my system. Then I installed windows in other drive. But on start up windows gets automatically loaded without askin for the option to choose between os. How do I get the option to choose which os to boot?

anirudhkumar_r,
I hope you mean that you installed a version of Ultimate Edition, as that is the forum your posting to. If not, why not try one of the current releases of Ultimate Edition, such as 2.7 or even the 2.8 Beta? However, the following information is correct for either UBUNTU (the base of Ultimate Edition) and Ultimate Edition.

If you had installed Windows first, and then installed Ultimate Edition (or UBUNTU), all would have been setup correctly by the install of Ultimate Edition (or UBUNTU). If I were you, and I had not yet done much configuring/installing apps or modifying the system settings in Ultimate Edition (or UBUNTU), I'd re-install Ultimate Edition (or UBUNTU) - to the same partitions/drive you originally used - and let it correct this problem. After the normal install of Ultimate Edition (or UBUNTU) on a system with other OSs (Windows, other Linux OSs, etc...), your re-boot would take you to a Grub Boot Menu and allow you to select the OS you wish to boot. This would be the easiest method, I believe.

Should you need further assistance please post back here with your request.

Here are a couple of screenshots of my Ultimate Edition install....

Thank you Mike for ur reply.

Now if I re-install ubuntu, I know i would get the grub from which I could choose the OS. But in future, if at all it happens that I have to re-install Windows due to some crash, I would again have to re-install ubuntu. Is there no way in which I can choose the OS to boot, not bothering the order in which I have installed ???
