What Is Rufus?
Rufus is a free and open-source utility designed primarily for formatting USB flash drives and creating bootable USB media. It can turn a compatible ISO image into bootable installation or recovery media for Windows, Linux, UEFI environments, and other supported utilities.
Rufus is useful when you need to:
- Create a bootable Windows USB.
- Create Linux installation media.
- Prepare UEFI boot media.
- Install or reinstall an operating system.
- Prepare recovery or troubleshooting media.
- Format USB flash drives.
- Run certain low-level utilities from bootable media.
Important: Creating bootable media can erase existing data on the selected USB drive. Back up important files and confirm the correct USB device before clicking Start.
Rufus Main Features
Create Bootable USB Drives
The main purpose of Rufus is to create bootable USB drives from ISO images. Instead of simply copying an ISO file to a USB drive, Rufus prepares the USB so a compatible computer can boot from it.
Create Windows Installation Media
Rufus is commonly used to create Windows installation USB drives. It can help with clean installations, Windows reinstalls, new-PC setup, and recovery or troubleshooting tasks.
Linux ISO Support
Rufus is not limited to Windows. It can create bootable USB media from supported Linux ISO images, making it useful for users who work with multiple operating systems.
UEFI and BIOS Support
Modern computers commonly use UEFI, while older systems may use legacy BIOS. Rufus can provide partition-scheme and target-system options so the bootable USB can be configured for the target computer.
USB Formatting
Rufus can format USB flash drives as part of the bootable-media creation process. Formatting prepares the drive for the selected file system and boot configuration.
Portable Operation
Rufus can be downloaded and launched directly without a traditional installation process. A portable build is also available for users who want to keep Rufus on removable storage or in a technician toolkit.
Rufus Download Options
| Version Type | Recommended For |
|---|---|
| Standard x64 | Most modern 64-bit Windows PCs |
| Portable x64 | Technicians and portable toolkits |
| x86 | Compatible 32-bit Windows systems |
| ARM64 | Compatible Windows ARM devices |
For most modern Windows 10 or Windows 11 computers, the standard x64 build is the simplest choice. Users with 32-bit Windows should choose x86, while compatible Windows-on-ARM devices require the ARM64 build.
Rufus 32-bit vs 64-bit vs ARM64
The correct Rufus version depends on your Windows architecture. To check it, open Settings → System → About and look for System type.
64-bit Windows: Use Rufus x64.
32-bit Windows: Use the x86 build.
Windows on ARM: Use the ARM64 build.
Rufus Portable vs Standard
Both versions are easy to use. The standard x64 build is the normal choice for most users. The portable version is useful when you want to carry Rufus on a USB drive or keep it as part of a troubleshooting toolkit.
GPT vs MBR in Rufus
| Partition Scheme | Common Use |
|---|---|
| GPT | Modern UEFI-based computers |
| MBR | Older Legacy BIOS systems |
GPT is the newer partitioning scheme and is commonly used with UEFI-based systems. MBR is older and is commonly associated with legacy BIOS. There is no universal setting that is correct for every computer, so match the configuration to the target PC.
How to Download Rufus Safely
The safest way to download Rufus is from the official Rufus website. Choose the build that matches your Windows architecture and avoid modified or repackaged versions from unknown sources.
Avoid:
- Modified Rufus executables.
- Unknown repackaged versions.
- Suspicious download managers.
- Unofficial software bundles.
How to Create a Bootable Windows USB With Rufus
Before starting, you need a Windows ISO file, a compatible USB flash drive, a Windows computer, and Rufus.
If you still need the installation image, see our Windows 11 ISO Download guide before creating the bootable USB.
- Connect the USB drive: Insert the USB and confirm that it has enough storage for the ISO.
- Open Rufus: Launch the Rufus executable and verify the device shown in the Device field.
- Select the ISO: Under Boot selection, choose the ISO image stored on your computer.
- Select the partition scheme: Choose GPT or MBR according to the target computer.
- Check the target system: Common combinations include GPT → UEFI and MBR → BIOS/UEFI-CSM.
- Review the file system: Rufus may choose an appropriate file system automatically.
- Click Start: Review any additional Windows User Experience options carefully.
- Confirm data erasure: Make sure you selected the correct USB before approving the warning.
- Wait for completion: Do not remove the USB while Rufus is writing the image.
How to Boot From the Rufus USB
- Connect the bootable USB to the target PC.
- Restart or turn on the computer.
- Open the manufacturer’s boot menu.
- Select the USB device.
- Start Windows Setup or the selected bootable environment.
The exact boot-menu key varies by manufacturer. Common keys can include F12, F9, Esc, or another manufacturer-specific key.
Rufus Safety Tips
- Confirm the correct USB drive before starting.
- Back up important files from the USB.
- Use an ISO from an official or trusted source.
- Check GPT/MBR and UEFI/BIOS settings.
- Read Windows User Experience options before enabling them.
- Do not disconnect the USB while Rufus is writing.
Rufus Troubleshooting
Rufus Does Not Detect the USB Drive
Disconnect and reconnect the USB, try another port, check whether Windows recognizes the drive, restart Rufus, or test another USB drive.
Rufus Shows the Wrong USB Drive
If multiple removable drives are connected, verify the device name, capacity, and manufacturer before starting. Never assume the first listed device is the correct one.
Rufus Says the ISO Is Not Bootable
The ISO may be damaged, incomplete, incorrectly created, or not intended to be bootable. Download the ISO again from its official source when possible.
Bootable USB Does Not Boot
Check the boot order, boot-menu selection, UEFI/Legacy BIOS mode, GPT/MBR configuration, USB port, and USB compatibility. Recreate the USB with settings that match the target system if necessary.
Windows Installation USB Does Not Start
Verify that the ISO is valid, the USB was created successfully, the computer is actually booting from USB, the partition scheme matches the target system, and the PC meets the Windows installation requirements.
Rufus Stops During the Write Process
Wait for a reasonable amount of time, check whether the USB is still responding, try another port or USB drive, and test another ISO if the problem continues.
Is Rufus Free?
Yes. Rufus is free and open-source software released under the GNU General Public License version 3 or later. You do not need to purchase a commercial license to use the standard application.
