If you’re having difficulty installing Windows 11 from a USB, it can be incredibly frustrating. Not many people know their way around computers, so this can be a daunting task. Unfortunately, this is a common problem that many users are trying to solve.

When installing Windows 11, it is important to be aware of the various risks and problems. For example, USB installation can be susceptible to errors and hardware malfunctions. Make sure you use an official Windows ISO file when installing from a USB stick.

Some possible reasons for a failed Windows OS installation using a USB stick include incompatible hardware, insufficient disk space, or a malfunctioning USB port. If none of those issues apply to you, the best solution is to use a different installation method.

The process can be overwhelming and frustrating, especially if you don’t know the necessary tricks. But don’t worry, this article will help with that. Read on to know more about the fixes.

Why can’t I install Windows 11 from USB?

There are several reasons why your Windows installation may have failed. The following are some of the most common ones:

• One possible reason you can’t install Windows 11 from the USB stick is that your USB stick itself doesn’t work. Another possibility is that the USB may be corrupted or not formatted correctly.
• If the UEFI settings are configured incorrectly, they can interfere with the installation. So, it’s wise to make sure that the settings are configured correctly before starting the installation process.
• The Windows 11 installation on your PC requires quite a lot of space (at least 64 GB). If it doesn’t have enough free space, you can’t complete the procedure.
• The problem might be due to your USB drive not being bootable.

Here are a few possible fixes that might help you get rid of this issue.

How to install Windows 11 on USB drive if it’s not working?

✅ Pre-checks:

✔️ Check for compatibility

Before installing Windows 11, please refer to the PC Health Check app to confirm that your device meets the minimum system requirement.

That being said, if you are on a laptop or desktop with good specs, chances are that you will enjoy the new release. The Windows release information status for known issues is also available for your reference.

✔️ Try a different USB port

Before proceeding, it is important to make sure the USB port you’re using is not broken. To ensure this, switch to a different USB port and try installing Windows 11 from the USB drive again to see if the issue resolves.

1. Check if your PC is configured to install Windows 11 from a USB

One of the best preparatory steps before installing Windows 11 is to plug in a USB and configure your computer to boot from it. This setting isn’t enabled by default, and you’ll need to manually set it up.

1️⃣ Firstly, reboot your computer. When the manufacturer’s logo appears, there are often some keys or a key combination that you can use. This will depend on the make and model of the PC. Refer to your PC manufacturer’s website for the same.

When pressing a special key, you’ll most likely see another prompt appear. It will show which key to press. For example, some common keys are F8 and F12. The options might differ based on the computer setup.

You’ll most likely see a menu that has options for different boot-up types. On the top-right corner, you’ll see an option that indicates which key is likely to trigger what. Therefore, pay close attention to the screen.

Upon pressing the key, find the option to access CD-ROM or DVD-ROM and make sure it’s enabled.

2. Free up space to install Windows 11

1. Press Windows + X key and locate File Explorer.
2. Navigate to My PC and verify the disk with the Windows label has at least 20 GB of free space.
