There are few methods to do this, most of them involve running disk part commands and partitioning USB drive etc. which I think it makes harder for technically challenged people. Using this method it makes it very simple and can get the things done easily.
We are going to use Windows 7 USB/DVD download tool to create Windows 7 bootable USB stick.
Install Windows 7 from USB
Download Windows 7 USB/DVD Download Tool for free from Microsoft.
Install the Windows 7 USB/DVD download tool on your system.
Go to Start > All Programs > Windows 7 USB DVD Download Tool and open the application.
Now you need to click on browse and select the Windows 7 ISO Image and click next.
You’ll get two options to choose either USB or DVD, In this case you could select USB.
Once you select USB click on Begin copying.
Once it begin first it will format your USB drive and copy the installation files to it.
You’ll see the above screen once it’s complete. Then when you plug in your USB should be seeing this screen.
If this method fails then you could try the following manual creation method.
Open the command prompt (If its Windows 7/Vista open it as administrator) and type in Diskpart
Note: If it fails to find diskpart then you could download it from Microsoft.
Then type in list disk
In this case my USB device is Disk 4
Now type in Select disk 4
Now we have to clean the drive so type in the command clean and press Enter.
Now we have to set the USB as primary partition so type create partition primary.
Now type in active to make the partition active
Now to we need to convert the USB partition as FAT32 so we have to run the command
format fs=fat32 quick
In order to enter drive letter type in assign
Now you can start copying the Windows 7 installation files to the USB. Once that’s complete your Windows 7 USB Installation drive is ready.
