It will show you how you can keep both windows 7 and windows 8 on the same machine. It will give you the experience to make an informed choice between two.

Follow the steps accordingly -

1. Get Windows 8

The first thing you need to do is download Windows 8 Pro and place it on a DVD that we will use to install it. Of course, if you already have Windows 8 on a DVD or USB key, you can skip this part. If you don't, click Buy Windows 8 and we're off and running. Note: Unlike its predecessors, Windows 8 requires a valid Windows 8 key before you can install it.

2. Compatibility Check

Before you buy Windows 8, you'll download the Windows 8 Upgrade Assistant application. When you run that, it shows you this "Let's see what's compatible" screen. After it checks your machine for compatibility (it doesn't check to see if your copy of Windows is genuine, though), it lets you know whether software you're using will still work with Windows 8.

3. Here's What We Found

When the upgrade assistant is done, you'll get this "here's what we found" screen. Take a look at the compatibility details (which don't matter much since we're not upgrading) if you wish, and then click Next.

4. Choose What to Keep

Here's the "choose what to keep" screen, and because we're not upgrading but creating a clean installation for our dual-boot, select "Nothing," and click Next.

5. Buy It

Now it's time to buy Windows 8 Pro. Click Order, follow the payment instructions, and when you're done, you'll get a Windows 8 Pro product key on the "thanks for your order" screen. Copy that product key and paste it into a safe place, and I'd recommend you write that number down, too. You'll need it later.

6. Download It

The installation files begin downloading, and as you can see, it is fairly quick if you have a fast connection.

7. Create Media

Once the download is done and the download's checked and files readied, you end up on this screen. Select Install by creating media, then click Next.

8. Choose ISO

Choose to either create a DVD or USB key. If you don't have a DVD burner, you'll need to click "USB Flash Drive." For this guide, let's go with a DVD, where you'll choose ISO file (an exact image of the Windows 8 files that will go onto a DVD ). Click Save.

9. Creating the ISO File

Save that ISO file to a place you can find easily, such as your Desktop. After a few minutes, Windows will assist you in burning that file to a DVD.

10. Open DVD Birner

Click Open DVD Burner and place a blank DVD in the drive.

11. Burn, Baby

This window will appear. Click Burn, and soon you'll have Windows 8 on DVD.

12. Create a Partition

Next, let's create a separate area on your hard drive, called a partition, where Windows 8 can exist without bumping into Windows 7. You'll be able to choose which one you'd like to use when you boot your PC. To do this, click the Start menu, right-click Computer, and select Manage. Click Storage, and then Disk Management, and after a few seconds you'll see this screen. It shows you the drives available on your PC.

13. Shrink That Volume

Right-click the hard disk where you'd like to install Windows 8, then select Shrink Volume. It will determine how much space you have.

14. Give It Some Space

Decide how much space you would like to dedicate to Windows 8. Remember, you must have at least 20GB.

15. Allocate

You'll end up with a disk with a black bar on top, labeled "unallocated." Click on that. Keep clicking Next until you see "Format Partition." Do that, using the defaults.

16. Name It Something Meaningful

Give your new drive a recognizable name -- I chose "Windows8". You are now ready to install Windows 8 Pro, without affecting your Windows 7 installation.

17. Press Any Key

With your DVD in the drive, reboot your computer. When it's booting, you'll see a notification like this, asking you to press any key to boot from CD or DVD. And no, there is no such thing as the "any" key

18. Off and Running!

Choose your language, click "Install Now" and the installation is about to begin!

19. Enter Product Key

You did write down that product key, didn't you? Here's where you'll be asked to enter it. Do so, and then click Next.

20. Careful! Choose Custom

On this screen, be sure to click the second choice, "Custom." This is the choice that lets you do a clean install of Windows 8, rather than an upgrade. Click Next.

21. Carefully Choose the New Partition You Created

Here's where that recognizable name of the hard drive comes in handy. Be sure you click on the partition you created, and then click Next. Now you can sit back and relax for a while as Windows 8 installs.

22. Dual Boot Success!

Once the installation is done, here's the screen you'll see after your computer boots. You can choose either Windows 7 or Windows 8. If you don't select one of them in 30 seconds (and that time is adjustable), the default is Windows 8. Click "change defaults or choose other options" and you can designate your comfy old Windows 7 as the default.
