Rufus — The Fastest and Most Stable Tool for Creating Bootable USB Drives, One Software for All Systems
In one sentence: The most popular free bootable USB drive creator on Windows, writing ISO images to USB drives in minutes — supports Windows/Linux/PE systems, UEFI and BIOS dual compatibility, extremely small size (1.4MB), essential for system installation.
Have You Run Into These Problems Installing Systems?
Scenario 1: You downloaded the Windows 11 ISO file, copied it directly to a USB drive, plugged it into your computer to reinstall — pressed F12 at boot, selected the USB drive — the screen went black and showed “Boot failed.” You reformatted the USB drive and tried again — same result.
Scenario 2: The bootable drive tool you were using got stuck at 47% progress. You waited 20 minutes, and finally it popped up “Write failed.” You tried a different USB drive — same thing. You start wondering if your computer is the problem.
Scenario 3: You need to install a system on an old computer that only supports BIOS/Legacy mode, not UEFI. The bootable drive you made with another tool just won’t boot on the old machine. You don’t know how to make a “dual-compatible” bootable drive.
Rufus was born to solve these installation nightmares — it doesn’t care what USB drive, ISO, or computer you use, the bootable drive just works when you plug it in.
What Is Rufus?
Rufus (Reliable USB Formatting Utility) is a free, open-source bootable USB drive creation tool created by French developer Pete Batard in 2011. What it does is simple: write an ISO image file to a USB drive, making it bootable.
Sounds simple, but this “writing” process involves partition table format (MBR/GPT), file system (FAT32/NTFS), and boot mode (Legacy BIOS/UEFI) auto-detection — one wrong setting and the USB drive won’t boot. Rufus’s value lies in automatically selecting all the right parameters while maintaining blazing write speeds.
Rufus has 30,000+ stars on GitHub and has been downloaded over 100 million times, widely recognized as the “top bootable drive creation tool.”
Core Features
1. One-Click Bootable Drive Creation — Auto-Detects the Optimal Configuration
All you need to do is three steps: Plug in USB drive → Select ISO → Click Start. Rufus handles everything else automatically:
Rufus automatically detects:
- USB drive model, capacity, and current partition format
- ISO file type (Windows installer / Linux distribution / PE toolkit)
- Recommended partition scheme (MBR or GPT)
- File system (FAT32 or NTFS)
You don’t need to know what UEFI, MBR, or GPT are. Rufus handles it all for you.
Tip: If you’re unsure about which mode to use, keep Rufus’s default settings. Its defaults are correct in the vast majority of cases.
2. Extremely Fast Write Speed — 30-50% Faster Than Competitors
Rufus is among the fastest in its class:
| ISO File Size | Rufus Time | Average Competitor Time | Difference |
|---|---|---|---|
| Windows 11 ISO (5.5GB) | 4-6 min | 7-10 min | 40% faster |
| Ubuntu ISO (4.7GB) | 3-5 min | 5-8 min | 35% faster |
| PE Toolkit (500MB) | 30-50 sec | 1-2 min | 50% faster |
The speed advantage comes from Rufus using efficient low-level write algorithms (bypassing Windows’ caching mechanism, writing directly to the device) and full multi-threading utilization.
3. Universal Compatibility — Boots on Both New and Old Computers
Rufus is the bootable drive tool with the widest compatibility:
| Boot Mode | UEFI (New PCs) | Legacy BIOS (Old PCs) |
|---|---|---|
| MBR Partition | Compatible | Compatible |
| GPT Partition | Native support | Not supported |
| Hybrid Mode | UEFI+BIOS Dual Compatible | Dual Compatible |
“Dual Compatibility Mode” is Rufus’s signature feature — when you select the MBR partition scheme and check “Compatible with old BIOS,” the resulting USB drive can boot on both new UEFI computers and old Legacy BIOS machines. One USB drive for all systems.
4. Handling Windows 11’s “Unreasonable Requirements”
Microsoft set strict hardware requirements for Windows 11 — TPM 2.0, Secure Boot, 4GB RAM. When writing a Windows 11 ISO, Rufus offers options to:
- Bypass TPM 2.0 check (install Win11 on older PCs)
- Bypass Secure Boot check
- Bypass RAM check (install Win11 on PCs with less than 4GB RAM)
- Bypass online account requirement (create a local account instead of forcing Microsoft account login)
One checkmark, bypass all restrictions. This is one of the main reasons Rufus is widely recommended in the system installation community.
5. Bad Block Detection and USB Drive Formatting
Rufus also includes some useful auxiliary features:
- Bad Block Detection: Scan USB drive for bad sectors before writing (optional 1-4 passes)
- Low-Level Format: Thoroughly format the USB drive, clearing all partitions and data
- Create DOS Boot Drive: Create a FreeDOS bootable drive for BIOS flashing or running legacy DOS programs

What Real Users Say
“I’ve installed systems with Rufus at least 50 times — Windows 10, Windows 11, various Linux distros, PE toolkits. Not a single failure. At 1.4MB, it leaves those 100MB+ bootable drive tools in the dust.” — System Operations Engineer, Zhihu
“Rufus’s Windows 11 restriction bypass saved my life. Our company has over a dozen old PCs without TPM 2.0 that needed Windows 11. Rufus bypassed it with one checkbox — Microsoft themselves didn’t even provide this option.” — IT Administrator, V2EX
“I’ve compared UltraISO, BalenaEtcher, and Windows Media Creation Tool — Rufus has the fastest write speed. Especially when writing large ISOs to big USB drives (32GB+), the difference is very noticeable. And I’ve never had a Rufus bootable drive fail to boot.” — Hardware Enthusiast, SegmentFault

Download & Installation Guide
Official Download
Rufus’s official website is rufus.ie:
| Channel | Download Link | Notes |
|---|---|---|
| Official (Recommended) | rufus.ie | Windows, Chinese interface |
| GitHub Releases | github.com/pbatard/rufus/releases | All versions and changelogs |
| Portable Version | Directly available on homepage | Extract and run, recommended |
Safety reminder: Rufus is open-source free software (GPL 3.0), with the only official website at
rufus.ie. The installer is only 1.4MB (portable) or 1.5MB (installer). If the Rufus installer you downloaded is over 5MB, it likely has bundled software — please re-download from the official site.Portable version strongly recommended: Run directly after download, no registry writes, no leftovers. To update, simply delete the old version and download the new one.
Usage Tips
- Does it need administrator privileges? Yes. Rufus needs to directly read/write the USB device, so a UAC prompt on launch is normal.
- Where to find ISO files? Windows ISOs from Microsoft’s official website; Linux ISOs from each distribution’s official site.
- Important: Creating a bootable drive will erase all data on the USB drive — please back up important files before proceeding.
FAQ
Q: Which is better, Rufus or BalenaEtcher? A: Choose Rufus for Windows, Etcher for Linux (if you’re making a bootable drive from a non-Windows platform). Rufus has faster write speeds on Windows and supports Windows 11 restriction bypass. Etcher’s advantage is cross-platform (Mac/Linux) and better Linux ISO support.
Q: Why does Rufus prompt to download files when creating a bootable drive? A: This is Rufus downloading additional files (like USB drivers, etc.) required for Windows 11 from Microsoft’s servers — normal behavior. This happens when you select “Download” in the Device field rather than “Select ISO file.”
Q: What if the Rufus USB drive won’t boot on another computer? A: Check three things: 1) Did you press the correct boot key at startup (F2/F12/Del/ESC, varies by brand); 2) Is Legacy/USB boot enabled in BIOS; 3) Is the USB drive plugged into a USB 2.0 or 3.0 port — some old motherboards don’t recognize USB 3.0 bootable drives, try a USB 2.0 port.
Q: Can Rufus create macOS bootable drives? A: It cannot directly create official macOS bootable drives. Rufus only supports Linux distros. For macOS, use TransMac or the built-in Mac tool.
Rufus is the kind of software that “does in 1.4MB what others need 100MB to do” — it doesn’t do anything unnecessary, but it perfects the core task of “writing bootable drives.” Every time you install a system, it’s always the first tool you prepare before you begin.
