Rufus is a small, free tool that turns a USB flash drive into a bootable Windows 11 installer. It does the same job as Microsoft’s Media Creation Tool, but gives you more control: you can use an ISO file you already have, choose the partition scheme, and set options such as creating a local account during setup. This guide walks through making the drive and using it to install Windows 11, plus fixes for common problems.
What You Need
- A USB flash drive of at least 8 GB. Everything on it will be erased.
- A PC running Windows 10 or 11 to run Rufus. Current versions of Rufus need Windows 10 or later.
- A Windows 11 ISO file, downloaded from Microsoft’s Windows 11 download page.
- The latest version of Rufus from the official Rufus website. You can use the portable version, which runs without installing.
Step 1: Download Rufus and the Windows 11 ISO
Download Rufus from rufus.ie, and download the Windows 11 disk image (ISO) for x64 devices from Microsoft. Save both somewhere easy to find, such as your Downloads folder.
Step 2: Insert the USB Drive and Open Rufus
Plug in the flash drive, then double-click the Rufus file. Click Yes if User Account Control asks for permission. Rufus may ask whether to check for updates online. Allowing it keeps Rufus current.
Step 3: Select the Drive and ISO
- Under Device, choose your USB drive. Double-check the name and size so you don’t erase the wrong drive.
- Under Boot selection, click SELECT and choose the Windows 11 ISO.
Step 4: Check the Settings
- Image option: Standard Windows installation.
- Partition scheme: GPT for modern PCs with UEFI firmware, which includes every PC that meets Windows 11’s requirements. Use MBR only for older PCs that boot in legacy BIOS mode.
- Target system: UEFI (non CSM) when GPT is selected.
- File system: Leave it on NTFS. Rufus handles UEFI booting from NTFS automatically, and the Windows install files are too large for FAT32.
Step 5: Click Start and Choose Setup Options
Click START. Rufus shows a Windows User Experience dialog with optional tweaks. Depending on your version, they include:
- Removing the requirement for 4 GB of RAM, Secure Boot, and TPM 2.0.
- Removing the requirement for an online Microsoft account, or creating a local account with a name you choose.
- Setting regional options to match the current PC.
- Turning off data collection and skipping privacy questions.
- Turning off automatic BitLocker device encryption.
Choose only the options you need and click OK. Confirm the warning that all data on the USB drive will be destroyed, then wait for the status bar to say READY. This usually takes 5 to 15 minutes.
Step 6: Boot the PC from the USB Drive
Plug the USB drive into the PC where you want to install Windows 11. Restart and press the boot menu key (often F12, F11, F9, or Esc), or in Windows go to Settings > System > Recovery > Advanced startup > Restart now > Use a device. See how to boot from USB in Windows 11 for details.
Step 7: Install Windows 11
Choose your language and keyboard, click Install Windows 11, and follow the prompts. To erase everything and start fresh, choose a Custom install and delete or select the drive partitions as needed.

A Note About Unsupported PCs
Rufus can remove the TPM 2.0, Secure Boot, and RAM checks so Windows 11 installs on older hardware. Microsoft doesn’t recommend installing Windows 11 on PCs that don’t meet the minimum requirements and doesn’t guarantee updates or support for them. Read about installing Windows 11 on an unsupported PC before you decide.
Rufus or the Media Creation Tool?
Microsoft’s Media Creation Tool is the simplest option if you just want a standard installer for a supported PC. Rufus is better when you already have an ISO, need to choose GPT or MBR yourself, want a local account without workarounds, or are installing on an older PC. See how to make a bootable USB for Windows 11 for the Media Creation Tool method.
Troubleshooting
The PC Doesn’t See the USB Drive
Check that the partition scheme matches the PC: GPT for UEFI, MBR for legacy BIOS. Try a different USB port, preferably one directly on the PC, and turn off Fast Boot in the firmware settings if the drive still doesn’t appear in the boot menu.
Rufus Doesn’t List My Drive
Rufus hides fixed USB hard drives by default. Click the arrow next to Show advanced drive properties and check List USB Hard Drives. Unplug other USB storage to avoid choosing the wrong one.
“Secure Boot Violation” When Booting
Update to the latest Rufus and Windows 11 ISO, then recreate the drive. If the PC still refuses to boot, temporarily turn off Secure Boot in the firmware settings, install Windows, and turn it back on.
Setup Asks for a Microsoft Account Anyway
Recreate the drive and select the option to remove the online account requirement or create a local account in the Windows User Experience dialog. Microsoft has been removing local-account workarounds from recent Windows 11 builds, so these options may not work with the newest ISO. In that case, finish setup with a Microsoft account and switch to a local account afterward. See whether you can install Windows 11 without a Microsoft account for other options.
Frequently Asked Questions
Is Rufus safe?
Yes, when you download it from rufus.ie. It’s open source and widely used. Avoid copies from other download sites.
Will creating the USB erase it?
Yes. Rufus formats the drive, so copy any files you need to keep before you start.
Can I use Rufus on a Mac?
No. Rufus only runs on Windows. On a Mac, you’ll need another tool or a Windows PC to create the drive.
Does Rufus activate Windows 11?
No. Rufus only creates the installer. Windows activates with a digital license tied to your PC or a valid product key.
Can I use the same USB drive for files afterward?
Yes. When you’re done installing, format the drive in File Explorer to use it as normal storage again.
