Performing a clean install of Windows 8 is quite a straightforward process, which begins by booting from your choice of installation media (usually the Windows 8 install DVD or USB Drive). You may need to change your boot order settings depending on your system. Once you've booted from the Windows 8 installation source, you'll be presented with the following screen. Choose your language and keyboard preferences and then click "next": Next, simply click "Install now": You'll then see a "setup is starting" message, followed by the license agreement. Tick the accept box to continue installing: To perform the fresh install, click "Custom (advanced)": The next step is to choose your installation partition. Most users will have a single drive and will be performing a clean install, but may need to format the drive first. Advanced users can click the "drive options" button and resize partitions, but in this example we are simply choosing the 40GB unallocated partition and clicking "next": Now the install process begins and the operating system files are copied to your drive. This may take a while minutes on the speed of your computer and it will automatically restart several times: Once this process is complete you'll be shown the "License Terms" - just tick and click "accept": The next stage is to enter your PC name and click "next": At the next stage you are given the open to choose express or custom settings. In this example we customise the settings: First, you need to choose if you wish to share network locations and devices. If you're at home, then you'll probably want to answer yes - if you're connected to a public network then you'll probably want to answer no: The next stages involve customising other settings to your own preferences, so browse the options to choose how you want Windows 8 to act and click "next" until you reach the "log on" stage: You can choose to log on using a Windows Live account, allowing you to sync settings across systems. Click the button for the method you would like to use to continue. In this example we created a local account: If you're making a local account, choose your username, password and hint: Once you've clicked next, Windows 8 will take a few moments and then you'll see that you're all done!
