    Rufus

    Rufus

    Utility to create bootable USB flash drives

    Rufus is a standalone app designed to format and create a bootable USB drive for a large variety of ISOs. The app is just over 1MB in size and is notably faster than similar competitor apps such as the Windows 7 USB utility, Universal USB Installer, and UNetbootin. Rufus can come in handy when you need to simply format a USB drive, install an OS on a machine that lacks a CD/DVD-ROM drive, or when you need to boot an operating system temporarily without intentions of actually installing the media. This can be immensely useful while you're on the go or just need access to an OS for a temporary, isolated reason. The app can even be used to flash firmware to BIOS or other destinations by just using DOS. Even though Rufus is a tiny utility in comparison to other USB creation tools that can be rather bulky in size, it contends easily with the competition and creates bootable USB drives in record time!
