Windows 7 - Install Windows 7 Operating System - Part 1

Before we start the tutorial for installing Windows 7 I will make you aware of what you need to be able to accomplish this tutorial.

This tutorial can be used to install Windows 7 onto a new computer, an existing computer with a blank hard drive or an exisiting computer with a corrupt Windows 7.

By following this tutorial you will lose any data stored on the computer you use it on. You need to back up any data you require before following the steps through.

Items you need to complete this tutorial:

  • Windows 7 Media DVD
  • A Windows 7 product key or what is sometimes refered to as a COA.
  • Patience, and a cup of coffee!

Let's begin

installing windows 7 operating system

Switch your computer on and insert your Windows 7 CD into the cdrom drive. Depending on how quick your computer boots up, you may miss the signal to boot from CD so if need be switch off or reboot the computer once you have the CD in the drive.

When you see the prompt 'Press any key to boot from CD' press a key on the keyboard.

After a few seconds you will see the Windows 7 setup screen start to load.

Depending on the speed of your computer it will stay like this for a minute or so whilst all the drivers are being loaded to produce the graphical setup screen.

Eventually the welcome to Windows 7 setup screen appears.

You will notice that there are three drop down menus allowing you to set the language and keyboard options.

Use the mouse to click the appropriate drop down option such as 'Time and Currency Format' and select the relevant option for your country. If you prefer you can change these settings later.

Once you have chosen the appropriate language options click next to continue.

This is the start of the Windows 7 installation

You will notice the main option to click is 'Install Now' and further below there are a couple of other options, most notable 'Repair your Computer'. We will not go into detail here about that function but it is worth noting for the future.

Once you are ready use the mouse to click the 'Install Now' option.

This next page is a license agreement that Microsoft include.

You must accept the terms of offered by Microsoft to use the Windows 7 software. In a nutshell it wants you to confirm that you will not do anything detrimental to the software.

To accept the terms click the checkbox at the bottom of the screen to 'I accept the license terms' and click the next button at the bottom of the screen to continue.

You are now presented with two options. Custom or Upgrade.

If this computer doesn't contain a previous version of Windows such as Windows XP then you will need to click the 'Custom' button to install a fresh version of Windows 7.

Personally I would suggest not running an upgrade option even if you do have a previous Windows installed here. It is best to start from scratch on a clean disk. If you want to upgrade click the upgrade option.

We will be following the 'Custom' route so click the custom link.

You will now be prompted with the question 'Where do you want to install Windows?'. A box showing you the list of available hard drives is diplayed and will show how large the disk is. In our case it is 15.7 GB.

If you select 'Next' Windows 7 will create a partition for you on the available hard drive. We will create a partition manually here though.

Below the drive list you will see some options. Click the option labelled 'Drive Options(advanced)' and more options will appear.

You will now notice an option called 'New'.

Click the new button and more options will display. These options are designed to manage the different partitions on the hard drive.

You can read more in depth about partitions in our other tutorials.

The box that is now displayed is asking how much of the drive you wish to use for the Windows 7 installation. Accept the amount in the box and click 'Apply'.

You should now notice that there are two hard drives in the list. With your mouse click the second partition (not the one labelled reserved!) and then click the 'Next' button at the lower right of the window.

That will start the setup procedure to the selected partition.
