CDs and DVDs have gone old school today. In fact, most latest computers and laptops don't even support CD or DVD installation, making disk installation obsolete. 

Though you can still install movies or video games using CDs or DVDs, unfortunately, you need a bootable USB drive if you want to clean install Windows 7. 

A bootable USB is a simple USB drive that has an ISO image of the operating system you have installed on it. The ISO image contains all the information about the operating system found on an optical disk. 

Having a bootable Windows 7 USB can help you in many scenarios, such as: 

  • When you have to reinstall Windows 7 operating system on your computer 
  • If your hard drive gets damaged or corrupted 
  • When you already have the necessary installation files on your system, all you need to do is reinstall them 
  • When you want to run Windows 7 on your Mac, etc. 

Your bootable Windows 7 USB drive can help you a lot to clean install the OS. So, let's now check out how to create a bootable Windows 7 USB. 

How to Create a Bootable Windows 7 USB Using Rufus 

Traditionally, Microsoft Windows Installation Media Creation Tool is used to create a bootable Windows 7 USB. But unfortunately, this isn't possible for Windows users anymore because Microsoft has ended the support for Windows 7. 

Thus, you can't download Windows 7 ISO files any longer directly on your computer. And if your computer doesn't have Windows 7 CD or DVD installation, it will not be possible for you to downgrade to Windows 7 unless you have a bootable USB. 

So, one of the free alternatives to create a bootable USB drive for the Microsoft Windows Installation Media Creation Tool is Rufus. 

Rufus stands for The Reliable USB Formatting Utility with Source. It is a free and open-source application for Windows to format and create bootable USB flash drives. 

The software supports various bootable .iso files, including Windows installation and Linux distributions. It also lets you create MS-DOS, FreeDOS, and Windows To Go bootable USB drives. Further, you can format USB drives using FAT, NTFS, UDF, and many other file systems. 

To create a bootable Windows 7 USB using Rufus, you have to follow these steps: 

Step 1. Go to to download the latest version of Rufus on your computer. 

Step 2. Open up Rufus and insert your clean USB (at least 8 GB space) stick to your device. 

Step 3. Rufus will automatically detect your flash drive. After that, tap on the Device and select your USB from the dropdown menu. 

Step 4. Ensure that the Boot Selection option is set to Disk or ISO image and then hit on the Select. Rufus will now open a file explorer; you have to select the location of your Windows 7 ISO image and select it.
