Booting from a USB drive is essential for installing Windows, running live operating systems, or performing system recovery. If you’re using Windows 11 and want to know how to boot from a USB, this guide will walk you through the entire process, step by step.
Why Boot from USB?
Booting from a USB offers several benefits:
- Install or reinstall Windows 11 – A USB drive is faster and more convenient than a DVD.
- Run live Linux or recovery tools – Troubleshoot your PC without affecting the existing OS.
- Fix boot issues – Recover a corrupted system using recovery drives.
- Portable tools – Carry diagnostic or repair utilities on a USB stick.
What You Need Before You Start
- A bootable USB drive with the OS or tools you need.
- Windows 11 PC with USB ports.
- Optional: Another PC to create a bootable USB using tools like Rufus or Microsoft Media Creation Tool.
💡 Tip: Ensure the USB drive is at least 8 GB for Windows 11 installation media.
Step 1: Create a Bootable USB Drive
If you don’t already have a bootable USB, you can create one:
Using Microsoft Media Creation Tool:
- Download the Media Creation Tool from Microsoft’s official website.
- Insert a USB drive (all data will be erased).
- Run the tool and select Create installation media for another PC.
- Choose USB flash drive and follow the prompts.
Using Rufus (Alternative):
- Download Rufus.
- Insert your USB and select the ISO file.
- Choose Partition scheme: GPT (for UEFI systems).
- Click Start to create the bootable drive.
Step 2: Access the BIOS or UEFI Settings
Booting from USB usually requires changing the boot order in BIOS/UEFI:
- Press Windows + I to open Settings.
- Go to System > Recovery > Advanced startup.
- Click Restart now under Advanced startup.
- Select Use a device > USB drive or Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
Alternatively, you can press a BIOS key during startup (common keys: F2, F12, Delete, Esc) to enter BIOS/UEFI directly.
Step 3: Change Boot Order
Once in BIOS/UEFI:
- Navigate to the Boot tab.
- Locate Boot priority/order.
- Move the USB drive to the top of the list using the on-screen instructions.
- Save changes and exit (usually F10).
💡 Tip: On modern PCs with UEFI, you may need to disable Secure Boot to boot some USB drives.
Step 4: Boot from the USB Drive
- Insert the bootable USB drive.
- Restart your PC.
- The system should boot from the USB automatically.
- Follow the on-screen instructions for installation, recovery, or live environment.
Step 5: Troubleshooting USB Boot Issues
- USB not detected:
- Try a different port (use USB 2.0 if available).
- Check if the USB is properly formatted as bootable.
- Secure Boot blocks USB:
- Disable Secure Boot in BIOS/UEFI.
- Wrong boot order:
- Ensure USB is first in the boot priority.
