The following steps show how to use Rufus to quickly create a bootable flash drive in Windows. Of all the available tools, Rufus, a free and open-source application, is one of the best. In fact, Rufus is one of the few necessary tools that every Windows user should have in their software catalog.

Tip: you can also use Rufus to format a USB drive in FAT32, which isn’t possible with the regular formatting tool in Windows 10 and 11.

What Is a Bootable USB?

A bootable USB drive (or “Live USB”) refers to any USB hardware device whose file systems have been reformatted, enabling it to install an entire operating system. The bootable USB drive folder can be viewed in a File Explorer window and contains various setup files and preloaded commands. You can’t use a bootable USB to store normal text, image, music or video files unless you reformat it.

It is very difficult to find a CD/DVD ROM nowadays, so most people prefer to use a bootable USB drive instead to install an operating system or software edition. They’re lightweight and you can create clone images of bootable USB drives, which makes the data indestructible.

Along with a regular installer, Rufus also comes in a portable variant. Download the portable version if you don’t want to install Rufus on your system. In this case, we are downloading the portable version. After downloading the .EXE file, install and open Rufus.

Frequently Asked Questions

Is Rufus safe to use?

Rufus is an extremely safe software application, as it is totally free of malware, advertisements, or bundled crapware, making it a leading recommended program to create bootable USB drives. Its portable version doesn’t even require installation on your device.

Is Rufus available in Linux or Mac?

Unfortunately, Linux is only available with Windows. It does not support either Linux or Mac, but these Rufus alternatives do: BalenaEtcher (Windows, macOS, Linux), PowerISO (Windows, macOS, Linux), and Ventoy (Windows, Linux).

Windows has a ton of other software programs to help you create bootable USB drives. Even Microsoft has its own tools that allow you to create a Windows installation media on a USB drive.

Why is my bootable USB with Rufus not working?

If your bootable USB created with Rufus fails to load properly, it means the boot mode (UEFI or legacy BIOS) of your USB drive may be different from that of the computer in which you are installing the operating system. Converting legacy BIOS to UEFI is the best way to ensure a successful boot.
