Rufus vs balenaEtcher: Which Bootable USB Tool to Use?

Pick Rufus if you are on Windows and need a bootable USB drive from an ISO, especially a Windows 10 or 11 installer, or a DOS drive to flash a BIOS. Pick balenaEtcher if you are on macOS or Linux, or you want the simplest possible way to write a Linux or Raspberry Pi image to a USB drive or SD card and have the write checked for you.

Both are free and open source, and both turn a disk image into a bootable drive. Rufus gives you many options and runs only on Windows. Etcher has three steps, runs everywhere, and says plainly that Windows ISOs are not its job.

Rufus vs balenaEtcher at a glance

Can balenaEtcher make a Windows 11 USB?

Not reliably, and this is the single biggest difference. We checked balenaEtcher's FAQ on 6 November 2026. To the question "Can Etcher write Windows ISO?", it answers: "Windows images are not bootable without extra treatment that etcher is not designed to do." It points Windows users to its documentation instead.

Rufus is built for exactly this job. After you press Start with a Windows image, it opens a Windows User Experience dialog where, according to the Rufus FAQ, you can find the options to bypass the TPM and Secure Boot checks of Windows 11. It can also create Windows To Go drives, which run Windows straight from USB. If you need a Windows installer, use Rufus.

Which is easier to use?

balenaEtcher is easier. Its site describes "an intuitive 3-step process with no command lines": pick an image, pick a drive, flash. It also hides your system drives by default and shows warnings, so you are less likely to wipe your computer's own disk by mistake.

Rufus is still straightforward for a basic job, since you choose a drive and an ISO and press Start. But it exposes more settings, and some Linux images can be written in either ISO mode or DD mode. The Rufus FAQ has a long section explaining why it recommends ISO mode for ISOHybrid images. That is helpful if you want control, and confusing if you just want a working stick.

Which one checks that the drive was written correctly?

Etcher does this automatically. Its "Validated Flashing" feature "confirms that your flash has completed", so you know the card or drive will boot and is not corrupted.

Rufus handles checking differently. It has a checksum button next to the image selector that computes the MD5, SHA-1 and SHA-256 of your ISO, so you can confirm the download is genuine before you write it. It also has an optional bad blocks test for the USB drive, which is off by default because it is slow. It does not re-read the drive after every write the way Etcher does.

Do they work on macOS and Linux?

Only Etcher. Its FAQ says it works on Windows 10 and later, Linux (most distros) and macOS 10.10 (Yosemite) and later. The 2.1.9 release on GitHub includes builds for Windows x64, macOS on Intel and Apple silicon, and Linux x64 as .deb, .rpm and zip files.

Rufus needs Windows 8 or later. Its FAQ says there are no plans to port it to Linux or macOS because it is built closely around Windows APIs. On the plus side, Rufus has a portable version that runs without installing anything.

Can they write to SD cards?

Etcher is made for it. Its tagline is "Flash OS images to SD cards & USB drives", and balena built it because its own users needed an easy way to flash SD cards. Rufus describes itself as a tool for "bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.", so for SD cards Etcher is the more natural fit. Rufus's list of supported ISOs does include Raspberry Pi OS.

Whichever you use, back up the drive first. Etcher's FAQ says it "will erase the whole drive", and Rufus deletes all partitions each time it creates a drive.

Which should you choose?

• You need a Windows 10 or 11 install USB: Rufus.
• You want to skip Windows 11 TPM and Secure Boot checks: Rufus.
• You need a DOS drive to flash a BIOS: Rufus.
• You are on macOS or Linux: balenaEtcher.
• You are flashing a Raspberry Pi or other SD card image: balenaEtcher.
• You want the fewest choices and an automatic check: balenaEtcher.
