MAKE SURE YOU BACKUP ANYTHING YOU WANT BEFORE YOU START OR ELSE IT WILL BE GONE!!!!

The first thing you want to have before you start is your Windows 7 PRODUCT KEY. On laptops it is located on the bottom and on store bought desktops it is located somewhere on the computers case.

If you can still boot into Windows, but just want to do a clean install to free up some room, you can use HTG’s article, http://www.howtogeek.com/75496.....activate/, to reinstall Windows without having to reactivate OR you can just enter your product key during the installation process of Windows. It just depends on what you think is easier, both work.

To start off, you need to have a Windows 7 Installation disc. If you don’t have one, you can get the official Windows 7 Service Pack 1 ISO from Digital River, http://www.mydigitallife.info/.....al-river/. When you download the ISO, make sure you have the correct version of Windows (i.e. Home Premium, Professional, or Ultimate).

Once you have the ISO file downloaded, you will have to burn it to a DVD or USB. I’m not going to go over how to burn a DVD, just how to make a bootable USB. I use Rufus Bootable USB, http://rufus.akeo.ie/, to do this.

First thing is to download Rufus and open it. Rufus doesn’t need to be installed so it just opens when you click the downloaded file.

Once Rufus is open, you need to select “Quick Format, Create a bootable disk using: ISO Image, and Create Extended label and icon files.” After those are checked, click the CD drive icon to the left of “ISO Image” and choose the Windows 7 ISO you just downloaded from the link above.

BEFORE YOU CLICK START, MAKE SURE YOU HAVE THE FILES YOU WANT TO KEEP OFF OF YOUR USB DRIVE BECAUSE RUFUS WILL FORMAT THE DRIVE. Once you’re sure, click start, then ok!

Rufus is now going through the steps of making the USB drive bootable and copying the Windows 7 setup files from the ISO to the USB.

Once Rufus is done, it will say this:

Now that you have a bootable USB, you have to set your computer’s BIOS to boot from USB. Every BIOS is different, but it should be in a menu called something like BOOT.

Once your computer is set to boot from USB and you have booted, you will get the Windows 7 Halt Screen:

At this screen press (SHIFT + F10) to open a command prompt window:

In the CMD window, type in Each Command and Press <ENTER> Key as follows:

DiskPart <ENTER>

list disk <ENTER>

select disk 0 <ENTER>

clean all <ENTER> (Will Take a While)

create partition primary align=1024 <ENTER>

format fs=ntfs <ENTER> (Will Take a While)

assign <ENTER>

active <ENTER>

exit <ENTER>

exit <ENTER>

IMMEDIATELY Click Out On Top X, TERMINATE Installation Process and REBOOT.

Once you go through the first halt screen, you will come to this screen:

Click “Install Now.” You are now at the License Terms screen. Accept them if you agree (if you don’t, you can’t install) and press “Next.”

Now you want to choose “Custom (advanced).”

There will now be ONE partition. DO NOT ALLOW WINDOWS TO FORMAT! Choose this partition to install Windows to and click next.

Windows is now installing:

Your computer will restart a couple times after the “Completing installation” step.

Your computer will now boot into Windows 7. Setting up everything else is going to be straight forward.

If your computer boots into the installation instead of Windows 7, turn your computer off, remove the USB drive, and turn your computer back on. Now you should be booting into Windows 7.

Also, if you are using the Reinstall Windows without Reactivating method, skip the window where you enter your product key. If you ARE using the product key, enter it in this window.

I hope this helps you do a clean install of Windows 7!
