Rufus 4.15 Final

Rufus turns an ISO file and a USB stick into a drive your PC can start from, ready to install or repair Windows or Linux.

It is a single 2 MB program that runs without installing, and it is free and open source with no ads.

For a Windows 11 install stick, it can also skip the TPM check and the forced Microsoft account.

What Rufus Actually Does

An ISO is a disc image, a single file holding everything that would be on an install DVD. Copying it to a USB stick does not make the stick bootable, so Rufus writes it in a way your PC's startup firmware can read.

Pick the stick, pick the ISO, press Start. Rufus chooses the right partition layout and file system for the image, so most people never touch the other settings.

• Windows and Linux. Install sticks for Windows 8, 10 and 11, and live or install drives for most Linux distributions, plus FreeDOS.
• Old and new PCs. Drives that start on both older BIOS machines and modern UEFI systems, with Secure Boot left on.
• Linux persistence. A storage partition so a live Linux stick keeps your files and settings between restarts.
• Drive checks. A bad-block scan that also catches fake flash drives that claim more space than they have.
• ISO download. Fetches official Windows 8, 10 and 11 ISOs from Microsoft if you do not have one.
• File systems. FAT32, NTFS, exFAT, UDF, ReFS and ext2/ext3 for formatting.

It is also fast. The developer's own tests put it at about twice the speed of older tools such as UNetbootin when writing a Windows install drive.

Windows 11 Without the Hurdles

When you write a Windows 11 ISO, Rufus shows a short list of options before it starts. These change how the finished stick installs Windows, not Windows itself.

• Hardware checks. Remove the TPM 2.0, Secure Boot and 4 GB RAM requirements for older PCs.
• Local account. Skip the forced Microsoft account and create a normal local user instead.
• Privacy. Answer the data-collection questions "no" automatically, and turn off automatic BitLocker encryption.
• Quality of life. New in 4.14, an option to keep Teams, Outlook, Copilot and other bundled extras from being pushed onto the new install.

Our step-by-step guide to installing Windows 11 on unsupported hardware with Rufus walks through each option. If you would rather stay with Microsoft's own route, the Windows 11 Installation Assistant upgrades supported PCs in place.

How to Make a Bootable USB

• Plug in a USB stick of at least 8 GB for Windows, or 4 GB for most Linux images. Everything on it will be erased, so copy off anything you need first.
• Open Rufus. It lists only removable drives by default, which keeps your internal disks out of harm's way.
• Click Select and choose your ISO, or use the arrow next to it and pick Download to fetch Windows from Microsoft.
• Leave Partition scheme and File system on the values Rufus picks, unless a guide for your PC says otherwise.
• Press Start, confirm the warning, and wait for the green Ready bar.

Which Download to Take

The Rufus download page carries several builds of the same program. None of them installs anything; the difference is where the program can run and where it saves its settings.

Rufus 4 needs Windows 8 or later to run. If you are keeping an old machine going, our guide to Windows 7 in 2026 covers the safety side.

What Is New in Rufus 4.15

Version 4.15 arrived on 30 June 2026 and is mostly a fix-up release for the big Windows changes in 4.14.

• Silent install fixed. It no longer stops at 75%, and it has stricter guards before it runs.
• ARM fixes. A boot crash on Snapdragon X laptops using UEFI:NTFS is gone, and RISC-V 64 support is added.
• Security. A flaw in the XML parser Rufus uses was closed.
• Windows ISOs. An endless loop with ISOs holding several Windows images is fixed, along with OneDrive removal and username checks.

What People Use It For

Repair is the big one. A stick from Rufus starts a PC that will not boot, and our guide to creating a bootable USB recovery drive shows how to use it.

Clean installs come next, on laptops with no disc drive or on a PC you want to wipe and start fresh. Running a live Linux stick to try a distro or rescue files without touching the hard drive is a close third.

Rufus can also build Windows To Go drives, a full Windows you carry on an external disk. Our guide to a portable Windows installation on SSD covers that setup.

When Another Tool Fits Better

The tell is how many ISOs you want on one stick. Rufus writes one image per drive and wipes it each time, which is ideal for a single job and tedious for a toolkit.

• Ventoy makes a multi-boot stick where you simply copy ISO files on, with no reformatting between them.
• YUMI is another multi-boot builder with a menu of distros to pick from.
• balenaEtcher is the simplest for Raspberry Pi SD cards and IMG files, and runs on Mac and Linux too.
• WinToUSB focuses on portable Windows drives, with more control than Rufus offers.
• Flyoobe upgrades an existing PC to Windows 11 in place, skipping the hardware checks, without making a stick at all.

To back up a whole disk rather than make an installer, Clonezilla is the free cloning tool, and it boots from a Rufus-made stick.

Tools That Pair Well With It

Have an install disc instead of an ISO? ImgBurn reads it into an ISO that Rufus can write.

To peek inside an ISO before writing it, 7-Zip opens it like a folder. To test an ISO without a spare PC, run it in a virtual machine with VMware Workstation Pro first.

The SSD and USB Tools category has the rest of the drive and boot utilities.
