With a clean installation of Windows 7, the computer installs a new copy of Windows 7 and erases all your files, programs, and applications or user settings. Be sure to back up your any files on the partition before performing Windows 7 installation. I defiantly recommend you to copying your documents, email, and other data such as all the installation files for the applications and your system hardware drivers to an external hard drive.
Step 1 would be to turn on your computer, insert the Windows 7 installation DVD in your computer's optical drive or USB flash drive, and then shut down your computer. Step 2 you would restart your computer, after the BIOS screen flashes by, press any key when prompted "Press any key to boot from CD or DVD". If your system does not boot from the DVD or USB flash drive, and you're not asked to press any key, you may need to change some system settings. Step 3 after loading Windows 7 installation files, the Install Windows screen appears, here you can enter the language, time and currency formats and then click Next button. Step 4 you continue with Windows 7 Interactive Setup, click Install now. Step 5 on the next screen please read the license terms page appears, you must agree to the End User License Agreement. If you accept the license terms, click I accept the license terms check box, and then click Next button. Step 6 you have to choose which type of installation you want? Custom (Advanced) or Recommended (Easy). I always recommend the easy route and not wasting time with the advanced route unless you have knowledge of the computer and how windows 7 installation works. Step 7 where do you want to install Windows? Choose the disk, or partition, to which you want to install Windows 7 on, and then click Next button. Step 8 after you have selected the disk or partition where you want to install Windows 7, the setup will start copying various installation files, expand the Windows 7 image file from the DVD to the hard drive, install Windows 7 and complete the installation by configuring your hardware devices. Lastly this process requires several automatic restart. When the Windows 7 installation finishes, the windows 7 operating system will be loaded. After the final reboot, you can complete the second, and final, interactive phase of installation, which include naming your computer and setting up an initial user account.
