USB is a much faster way to go if you want to install Windows 7 from the scratch. In this post, we will show you in step by step guidance how to create and use the bootable USB flash drive to install Windows 7 from the very beginning. 

Before we begin
Step 1: Create or Download an ISO
Step 2: Create an Installation USB Drive 
Step 3: Install Windows 7 via USB

Before we begin

Note: Please make sure that your USB flash drive is with at least 8 GB of free storage and that there is no important data in it since all the data will be erased completely later. 

We are now getting your USB flash drive ready by erasing the entire contents of the drive. 

1) Insert your USB flash drive into your computer. 

2) Press the Start button on your keyboard, type cmd in the search box. Right-click cmd and click Run as administrator



3) Type the following commands into the cmd window and press the Enter key on your keyboard after each command: 

a) diskpart 

b) list disk 

You can see which disk is your USB drive listed. Yours could be listed as Disk 0, Disk 1, or Disk 2. On our screen shot, the USB drive is listed as Disk 1

c) select disk 1

Note: If your USB flash drive is listed as Disk 0, Disk 2 or some other numbers, you should change the 1 here accordingly. 

You will see the notification saying that “Disk X is now the selected disk“. 

d) clean



You will see a successful response saying that “DiskPart succeeded in cleaning the disk.” 

e) When the drive is cleaned, we need to format the USB flash driver. Type in the following commands, and hit Enter after you type each of the command: 

select disk 2 (or what number your USB drive has)

create partition primary

select partition 1 

active

format FS=NTFS



Step 1: Create or Download an ISO

Download the Windows 7 SP1 ISO from Microsoft’s website. You need to provide your product key (in the form of xxxxx-xxxxx-xxxxx-xxxxx-xxxxx) to download the file. 

The instructions on the site are pretty easy and straight-forward to follow. 

Step 2: Create your Installation USB Drive 

1) Download Windows USB/DVD Download Tool. Even though it’s stated to be appropriate for Windows 7 and XP, it’s totally OK for you to create Windows 8, Windows 10 setup file with it. 

2) Double-click the setup file to install Windows USB/DVD Download Tool. Then double-click it to run.

3) Click Browse to locate the Windows 7 ISO file that you have downloaded and click Next to continue. 

4) Click USB device.

5) Choose from the drop down menu the USB flash drive that you want to use. Then click Begin copying

6) Now wait for the process to complete. 

7) Exit the download tool when the process finishes. 


Step 3: Install Windows 7 via USB

Now you can start your PC from USB or you can change the boot order so it will boot from the USB first to run the installation of Windows 7.
