What's Rufus?

Rufus should not be strange to most computer savvy who plays a lot and knows well about their computers and operating systems. Indeed, Rufus is a free and open-source portable application in small size for Microsoft Windows, and it provides experienced consumers with almost everything they need, including two of the most popular features. One is to low-level format a USB flash drive or memory stick, and the other is to create USB installation media from bootable ISO files of Windows, Linux, UEFI, etc.

About Rufus Bootable USB

The Rufus bootable USB feature is used to create bootable USB drives so you can clean install Windows operating system on a none-bootable computer that needs repairing or upgrading to a newer operating system like Windows 11.

The standard procedure of creating a Windows USB drive with Rufus requires an empty clean USB flash drive of 8GB bigger, and a downloaded ISO file of Windows 11 or Windows 10. In short, the USB drive's capacity is at least equal to or larger than the ISO file. Turning a normal USB to bootable will completely remove data if there is any, so make sure that you've transferred the data to another drive to keep it safe if the USB flash drive is a used one.

How to Create A Bootable USB Using Rufus

As we mentioned, you can start using the Rufus bootable USB option when your case is involved in the following cases:

  • You need to burn a Windows 11 or Windows 10 ISO file to a USB drive
  • You need to create USB installation media for Windows 11 or Windows 10
  • You need to work with a computer with the startup issue
  • You need to boot a computer that does not have any OS installed

With those cases in mind, it's useful to create a bootable USB drive so that you can install any supported Windows operating system (Windows 7 and later of both 32-bit and 64-bit) to be able to repair a computer, reinstall OS, or manually do a Windows upgrade.

Bonus Tip: Bootable Windows USB vs. Portable Windows USB

After staying for a while with the Rufus guide, you should be clear that a Windows bootable USB drive carries a Windows installation file (ISO) so that you can install a fresh, working and stable new Windows OS on your PC and laptop. However, sometimes your purpose of having a bootable USB drive is not for Windows installation, but a simple demand for a portable version of a desired operating system. 

If your request for a bootable Windows 11/10/8.1/8/7 USB drive is related to the following cases, you should try EaseUS OS2Go instead of Rufus:

  • You want to keep using the customized Windows OS on one computer to the other. 
  • You want to play Windows games on a Mac but don't want to install Windows OS on your Mac.

In a word, when you want to make a copy of one Windows computer on a USB drive and use the USB drive on any other Windows computer or a Mac machine without taking time to install, there you go. EaseUS portable USB creator can make it happen very seamlessly.

For Windows 11/10/8/7

The way of making a portable Windows OS on a USB drive is to migrate the whole Windows OS installation, programs, data, preferences, and user accounts on the computer to the USB drive. So, the requirement of the USB drive's capacity is based on the used space of the system drive. You can check the disk space for the Windows system drive (C:) at first, and find a proper USB drive to start with the below guide to create a portable Windows 11 or Windows 10 USB drive with EaseUS OS2Go.

Step 1. Install EaseUS OS2Go on your Windows computer, it will display your system drive's used space. Plug in a USB drive that is larger than the system drive used space. Choose the target USB drive and click Next to continue.
