This tutorial explains in a detailed 13 easy step-by-step procedure on how to install Windows 7 using the Windows 7 installation CD.

 This tutorial is created by me. I have really worked hard on this post as I do in every other post so I have one request. Please show your appreciation by not stealing this post and do not copying it as is without giving me the credit for it. I would really appreciate it. Thank You!

 Before you start this procedure.

1. Make sure to back up your data: First, make sure there is absolutely NOTHING you cannot afford to lose on the drive you're going to install Windows on (let's say the C: drive.) 
2. Make sure your network cable is unplugged from the wall (to avoid getting viruses from your local area network). 
3. You have a Windows 7 installation CD with a valid Product Key.
4. Hardware driver discs that shipped with the PC and any components you added on (Optional, but VERY strongly recommended) 
5. Time & Patience (you need to be calm and give the setup a little time)
