How to configure GRUB2 to give me the multi boot option
 

The hard disk inside my laptop looks like this

[ Win 8 ][ SWAP ][ Linux ][ Data ]

What are the steps to configure the GRUB2 to give me the option to dual-boot when I turn my laptop on?

If you boot into Linux then run update-grub as root it should add Windows 8 to the GRUB menu.

That is only true for Debian (Ubuntu) derivatives. Or used to be ... :p
OP needs to give more info.

Sory, yes, though there are similar commands on other systems.

Which linux distro it is?
Do you use a live cd/dvd to boot for installing grub?
Give output of 'fdisk -l'.

Read grub manual.

First backup your data and then have a look at this dual boot link:

If things get messy, I recommend that you keep a GRUB2 repair kit handy:

I realized the Mint installation did it perfectly even without asking for my permission, or asking me to enter any information!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
