Windows 7 Clean Installation

Install Windows 7 on a computer and format the hard disk during installation

What is a Windows 7 clean installation... It's a process of booting the Windows 7 installer manually without using Windows OS (BIOS settings: booting from CD/DVD) and formatting the hard drive during installation. Then the old operation system will be removed. Otherwise, booting the Windows 8 installer automatically using Windows OS is not a clean installation, because the old operation system will not be removed fully and you'll have problems of compatibilities in the future.

The main differences:
  • A clean installation: Turn on PC - BIOS settings (boot from CD/DVD) - Installation
  • An installation: Turn on PC - BIOS settings (boot from HDD) - Operation System (OS) - run CD/DVD - Installation

Backing up personal files, passwords and a list of PC components

Passwords and personal files - a data backup is the main step before a Windows 7 clean installation (copying and archiving the personal files and passwords). Backup programs help to do it. Also simply to know the passwords when you have used Mozilla Firefox. Open Mozilla Firefox and click Tools - Options - Security - Saved Passwords - Show Passwords. Make a PrintScreen (press Prt Sc key), then open Paint program, press Ctrl+V and save as .jpg format.

A list of PC components - for example, a sound doesn't work on your computer after installing Windows 7. Then find the name of adapter in the list of components, next type the name of components in Google search (realtek sound driver download Windows 7), download and install a sound driver. Everest Home Edition program helps to make a list of components easy and carefully. Type in Google search - Everest Home Edition download, download and install this program. If you do not have a list of PC components and a sound of PC doesn't work right now, then you need the program SlimDrivers or finding drivers by vendor. Windows 7 installation is made with formatting of hard drive, which guarantees reliable operation of your PC.
