Recovering GRUB (Bootloader) after windows installation

GRUB (GRand Unified Bootloader) is a bootloader package used to support & load an Operating System from a list of several operating systems already installed.

   I dont know about others but here at P.I.C.T most of the students install Linux on Windows with the help of WUBI (Windows-based Ubuntu Installer). When you run wubi on windows operating system it prompts many options but most of us select 'Install inside Windows'.

   I also have been doing the same since many of my last semesters, but I always used to face the same problem. The problem is 'how do I recover my Ubuntu installation if I reinstall a fresh copy of Windows operatin system.' This is where recovering GRUB comes into picture. So this time I just set my shoulders to go ahead and take a look into getting this all in charge.

SNORT is and Intrusion Detection System (IDS). We are given a problem statement as
"Study, Install and Configure any Intrusion Detection System (IDS)" in our lab manual.
I have just played with Snort for about 4 hours and now I am able to detect network traffic from internet to my computer and able to raise alert as specified in the rule file.
