Welcome to my step-by-step guide on how to boot and install Windows 11 from a USB drive! In a previous post, I explained how to create a Windows 11 ISO. Now, I’ll walk you through the process of booting from a USB drive and installing a fresh copy of Windows 11 on your device. Whether you’re using an Asus laptop like me or another device, this guide will help you navigate the process with ease. Let’s dive in!
Why Install Windows 11 from a USB Drive?
Installing Windows 11 from a USB drive is a great way to perform a clean installation, upgrade your system, or troubleshoot issues. A bootable USB allows you to:
- Install a fresh copy of Windows 11 for better performance.
- Recover a malfunctioning system.
- Test a modified Windows 11 ISO, as I’m doing on my Asus laptop.
Before starting, ensure you have a bootable USB drive with a Windows 11 ISO (at least 8GB capacity) and a compatible device meeting Windows 11’s system requirements (e.g., TPM 2.0, Secure Boot).
What You’ll Need
- A USB drive with a Windows 11 ISO (learn how to create one in my previous post).
- A laptop or desktop (this guide uses an Asus laptop).
- A backup of your important files, as formatting will erase data.
- Patience, as the installation may take 20–40 minutes.
Step-by-Step Guide to Boot and Install Windows 11
Step 1: Insert the USB Drive
Plug your bootable USB drive into a USB port on your computer. Ensure it’s securely connected to avoid interruptions during the boot process.
Step 2: Restart Your Device
Restart your laptop or desktop. For my Asus laptop, the restart process brings up the Asus logo. This is your cue to access the Boot Manager.
Step 3: Access the Boot Manager

As soon as the Asus logo (or your device’s logo) appears, press the ESC key repeatedly. The key may vary depending on your device:
- Dell: F12
- HP: F9
- Lenovo: F12 or Fn + F2
- Acer: F12 or Del
Check your manufacturer’s website for the correct key. Once in the Boot Manager, select the USB drive (it may appear as “USB: [Your USB Brand]” or similar). In my case, I choose the second option, which corresponds to my Windows 11 ISO.
Step 4: Start the Windows 11 Setup
After selecting the USB drive, you’ll see the Windows logo. The Windows Setup screen will appear, prompting you to:
- Confirm the language, time, and currency format. Click Next if the default settings (e.g., English) are correct.
- Select your keyboard layout. I kept the default US layout, but you can choose another if needed. Click Next.
Step 5: Choose Installation Option
You’ll see two options:
- Install Windows 11: For a fresh installation.
- Repair your computer: For troubleshooting.
Since I want a clean installation, I select Install Windows 11.
Step 6: Accept Terms and Conditions
Read and accept Microsoft’s Terms and Conditions by checking the box and clicking Next. This step is mandatory to proceed.
Step 7: Select the Installation Drive
You’ll now see a list of drives and partitions. Choose the drive where you want to install Windows 11. In my case, I use Drive 1, Partition 3 as my Windows drive.
Important: To avoid conflicts with old data, format the target drive:
- Select the drive or partition.
- Click Format to erase existing data.
- Confirm the action (ensure you’ve backed up important files!).
After formatting, select the drive again and click Next.
Step 8: Begin the Installation
Click Install to start the Windows 11 installation. The process may take 20–40 minutes, depending on your device’s speed and USB drive performance. Your device may restart several times—don’t worry, this is normal.
Step 9: Handle Post-Installation Prompts
If a “Press any key to boot from USB” screen appears, press Enter or any key to continue. Follow any on-screen instructions to complete the setup, such as configuring your user account, privacy settings, and network preferences.
Tips for a Smooth Installation
- Research Your Device: Boot keys and BIOS settings vary by manufacturer. Search for your device model’s boot menu key to avoid delays.
- Check System Requirements: Ensure your device supports Windows 11 (e.g., 4GB RAM, 64GB storage, TPM 2.0).
- Use a Reliable USB: A high-quality USB 3.0 drive can speed up the installation process.
- Backup First: Always back up critical data before formatting any drive.
- Modified ISO Caution: If using a modified Windows 11 ISO, ensure it’s from a trusted source to avoid security risks.
Troubleshooting Common Issues
- USB Not Detected: Ensure the USB is properly inserted and listed in the Boot Manager. Try another USB port if needed.
- Installation Stuck: If the process freezes, restart and try again. Verify the ISO file isn’t corrupted.
- Error Messages: Note any error codes and search Microsoft’s support site for solutions.
Conclusion
Booting and installing Windows 11 from a USB drive is straightforward with the right preparation. By following these steps, you can enjoy a fresh, optimized Windows 11 experience on your Asus laptop or other devices. If you encounter issues, research your device’s specific boot process or consult Microsoft’s official support.
