Windows 8, the latest OS from Microsoft was made available to Technet and MSDN subscribers and will be available for general public in October. If you have already got a Windows 8 license, you might be planning to install it. There are two options available, you can either clean install it or upgrade from Windows 7, Vista or XP. A Windows 8 clean install simply means an installation of Windows 7 on an unused partition on your hard drive. In most cases, though, a clean install of Windows 8 means to remove an existing OS and to replace it with a fresh installation of Windows 8.
In this article, we will cover how to do a clean install of Windows 8. For this installation, you will need a a bootable DVD or a bootable USB pen drive. You can also start the set up from your existing Windows installation.
Run the setup file or boot from the DVD or bootable USB. Select the language and keyboard and click next.
Enter the 20 digit product key for Windows 8 and click next. The set up will check the key for validity.
Now accept the license terms and click next.

In the next step, select the drive where you want to install Windows (assuming you already have multiple hard drives configured) or install on the default drive.
Click next and Windows will start the installation. First it copies all the files required, then it installs all the features.
