No Boot Menu Appears after Dual Boot Installation with Windows 7 Pro

Hello everyone,

I've a Windows 7 Professional laptop, and want to install Ubuntu 13.04 alongside Windows 7. But facing some issue. Here it is:

My laptop came with Windows 7 Pro (64-bit), and I've made 6 partitions (or logical drives, whatever it is called) in it. Recently I installed Windows 8 in my laptop (Dual boot with Win 7), but then I wanted to try Ubuntu, so I formatted Drive D: (in which Win 8 was installed) and through "msconfig", I removed Win 8 from boot option, so that my PC could directly boot into Win 7 (which it is doing perfectly).

Now when I want to install Ubuntu, it says, "Install Ubuntu alongside Windows 8" (and some other options).

Why it is detecting Win 8 (though I don't have it in my laptop anymore). It doesn't detect Win 7 in my laptop.

Anyway I went ahead and selected the option "Install ubuntu alongside Windows 8".
-Formatted one drive with ext4 and then there was some option where I selected "\" (I was not sure whether to select "\" or "\boot") :(

But after installation my PC directly boots to Win 7, no boot menu appears when I start my PC with options of Ubuntu and/or Win 7.

I searched online, couldn't really find any solution, but tried bootrec \fixmbr, bootrec \fixboot etc commands, but still ubuntu detects windows 8 in my laptop.

Can anyone please guide me how can I make ubuntu detect Windows 7 in my laptop and after installation it gives me boot menu options?

And one more thing, what should I select when formatting/selecting partition for ubuntu installation?
-ext4?
-\ or \boot or something else?

Thanks and sorry for such a long text :)
