Rufus is a tool that can be used to create a bootable USB flash drive with an ISO file. When you download it from the Internet, you might ask: is Rufus safe? Here, MiniTool Partition Wizard lists everything you need to know about Rufus and you can get the answer eventually.

What Is Rufus?

Rufus, short for The Reliable USB Formatting Utility, with Source, is the software developed by Pete Batard. It is a free and portable application that doesn’t require installation. To better understand this utility, let’s see its features:

  • Rufus enables users to create a bootable USB flash drive using an ISO file. It supports various bootable ISO files, including some Linux distributions and Windows installation ISO files, and raw disk image files.
  • Users can use Rufus to download an ISO image of Windows 10 or 8.1 to their computer. And they can configure the release, edition, language, and architecture type according to their needs.
  • It also allows users to create a full DOS-compatible environment to run legacy tools with FreeDOS and the MBR partition Scheme.
  • It provides advanced boot selection, including Syslinux 4.07, Syslinux 6.04, ReactOS, Grub 2.04, Grub4DOS 0.4.6a, and UEFI:NTFS.
  • It supports two partition schemes (MBR and GPT) for users who want to create a bootable media with ISO image.
  • Rufus allows users to format their USB flash drives to FAT, NTFS, FAT32, exFAT, UDF, and ReFS file systems, set the cluster size, and edit the volume label.

In a word, this software is an ISO burner that is mostly used to format and create bootable USB flash drives or Live USBs with an ISO file easily.

Tip: Most downloadable operating systems such as Windows and Linux distros are distributed as ISO images. Users can burn them to optical discs or USB flash drives and install these operating systems.

To run Rufus, your operating system needs to be Windows 7 or any later versions of 32 or 64 bit. By the way, Rufus provides 38 languages so that users can enjoy it more conveniently.

When you encounter severe system problems and need to reinstall Windows 10, you can burn the operating system into a USB flash drive with a Windows 10 ISO file. Rufus can help you finish the operation, and you can get it from the official website of Rufus. However, you might worry about safety issues when you download a new application.
