Step By Step How To Install Windows 7

Articles Jul 13, 2019 04:25

Sometimes when your computer fails so many times or have a lot of virus, installing a fresh copy of operating system is the best way. This is called clean install, erase everything on the current device and install a new fresh OS. Here are how to clean install Windows 7, step by step.

Most of the time, a Windows 7 clean install means to remove an existing operating system (like Windows XP, Linux, Windows 7, Windows 10, Windows 8, ...it doesn't matter) and replace it with a fresh or "clean" installation of Windows 7.

In other words, it's the "erase everything and start from scratch" process for Windows 7, a procedure referred to as a "clean install" or sometimes as a "custom install." It's the ultimate "reinstall Windows 7" process.

A clean install is often the best way to solve very serious Windows 7 problems, like a virus infection you can't get rid of completely or maybe some kind of Windows issue that you can't seem to solve with normal troubleshooting.

Performing a clean install of Windows 7 is also usually a better idea than upgrading from an older version of Windows. Since a clean install is a true start over from scratch, you don't risk inheriting any buggy situations from your previous installation.

To be 100 percent clear, this is the right procedure to follow if:

  • you want to erase whatever you have and install Windows 7.
  • you want to reinstall Windows 7.
  • you want to install windows 7 on a new hard drive.

This guide is broken into a total of 34 steps and will walk you through every part of the Windows 7 clean install process. Let's get started...

The steps and screenshots shown in these steps refer specifically to Windows 7 Ultimate edition but will also serve perfectly well as a guide to reinstalling any Windows 7 edition you may have, including Windows 7 Professional or Windows 7 Home Premium.

Microsoft has changed the clean install process for every new Windows release. If you're using Windows 10, 8, Vista, etc., see How Do I Perform a Clean Installation of Windows? for links to specific instructions for your version of Windows.

01. Plan Your Windows 7 Clean Install

Step By Step How To Install Windows 7

The most important thing to realize before performing a clean install of Windows 7 is that all of the information on the drive that your current operating system is installed on (probably your C: drive) will be destroyed during this process. That means that if there's anything you want to keep, you should back it up to a disc or another drive prior to beginning this process.

One quick way to back up the list of programs you have on your computer is with the CCleaner tool. It doesn't back up the actual program data but simply a list of what's installed so that you don't have to remember every program name.

NOTE: You should also locate the Windows 7 product key, a 25-digit alphanumeric code unique to your copy of Windows 7. If you can't locate it, there is a fairly easy way to find the Windows 7 product key code from your existing Windows 7 installation, but this must be done before you reinstall Windows 7.

If Windows originally came preinstalled on your computer (i.e. you did not install it yourself), your product key is probably located on a sticker attached to the side, back, or bottom of your computer's case. This is the product key you should use when installing Windows 7.

When you're absolutely sure sure that everything from your computer that you want to keep is backed up, proceed to the next step. Keep in mind that once you delete all of the information from this drive (as we'll do in a future step), the action is not reversible!

02. Boot From the Windows 7 DVD or USB Device

Step By Step How To Install Windows 7

To begin the Windows 7 clean install process, you'll need to boot from the Windows 7 DVD if you're using a Windows 7 DVD, or boot from a USB device if your Windows 7 installation files are located on a flash drive or other external USB drive.

TIPS: See our Windows Installation FAQ if you have Windows 7 as an ISO image that you need on a flash drive or disc, or a Windows 7 DVD you need on a flash drive.

  1. Restart your computer with the Windows 7 DVD in your optical drive, or with the properly configured Windows 7 USB flash drive plugged in.
  2. Watch for a Press any key to boot from CD or DVD... message similar to the one shown in the screenshot above. If you're booting from a flash drive, the message might be phrased differently, like Press any key to boot from external device....
  3. Press a key to force the computer to boot from the Windows 7 DVD or USB storage device. If you do not press a key, your computer will attempt to boot to the next device in the boot order, which is probably your hard drive. If this happens, chances are your current operating system will boot.

NOTE: If your existing Windows installation begins to boot or you see a "No Operating System Found" or "NTLDR is Missing" error here instead of the screen above, the most probable reason is that your computer is not set up to boot first from the correct source. To correct this problem, you'll need to change the boot order in BIOS to list the CD/DVD/BD drive, or External Device, first.

NOTE: It's perfectly fine if, instead of the screen above, the Windows 7 setup process begins automatically (see the next step). If this happens, consider this step complete and move on!

03. Wait for Windows 7 Installation Files to Load

Step By Step How To Install Windows 7

You don't need to do anything at this point but wait for Windows 7 to finish loading files in preparation for the setup process.

NOTE: No changes are being made to your computer at this time. Windows 7 is just temporarily "loading files" into memory for the setup process. You'll be removing everything on your computer as part of the Windows 7 clean install in a future step.

04. Wait for Windows 7 Setup to Finish Loading

Step By Step How To Install Windows 7

After the Windows 7 install files are loaded into memory, you'll see the Windows 7 splash screen, indicating that the setup process is about to begin.

You don't need to do anything at this point either.

05. Choose Language and Other Preferences

Step By Step How To Install Windows 7

Select Install now in the center of the screen, under the Windows 7 logo.

This will officially begin the Windows 7 clean install process.

NOTE: Do not select the Repair your computer link at the bottom of the window even if you're completing this clean install of Windows 7 as part of some larger repair project for your computer.

The Repair your computer link is used to start a Windows 7 Startup Repair or perform another recovery or repair task from System Recovery Options.

IMPORTANT: If you're performing a clean install of Windows 7 as a solution to a major problem but have not yet tried a Startup Repair, do that first. It could save you the trouble of completing this clean install process.

07. Wait for Windows 7 Setup to Begin

Step By Step How To Install Windows 7

The Windows 7 setup process is now beginning.

No need to press any keys here–everything is automatic.

08. Accept the Windows 7 License Terms

Step By Step How To Install Windows 7

The next screen that appears is a textbox containing the Windows 7 Software License.

Read through the agreement, check the I accept the license terms checkbox under the agreement text, and then select Next to confirm that you agree with the terms.

NOTE: You should always read "small print" especially when it comes to operating systems and other software. Most programs, Windows 7 included, have legally binding limits on how many computers the application can be installed on, among other limitations.

IMPORTANT: You are not breaking any laws or contracts by reinstalling Windows 7 via this clean install. As long as this particular copy of Windows 7 is only being operated on one computer, you're OK.

09. Choose the Type of Windows 7 Installation to Complete

Step By Step How To Install Windows 7

In the Which type of installation do you want? window that appears next, you're offered the choice of Upgrade and Custom (advanced).

Select Custom (advanced).

IMPORTANT: Even if you are upgrading from a previous operating system to Windows 7, I highly recommend that you do not follow the Upgradeinstallation. You'll get better performance with less chance of issues if you follow these clean install steps.
