How to Install Windows 10 from USB: A Step-by-Step Guide for Beginners

If you’re looking to upgrade or fresh install Windows 10, using a USB drive is a convenient method. This process involves creating a bootable USB drive with the Windows 10 installation files and then using that USB to install the OS on your computer. Let’s walk through each step to get this done smoothly.

How to Install Windows 10 from USB

In this guide, you’ll learn how to create a bootable USB drive and use it to install Windows 10 on your computer. By the end of this process, you’ll have a fresh installation of Windows 10, ready to use.

Step 1: Download the Windows 10 Media Creation Tool

First, head to the official Microsoft website to download the Media Creation Tool. This tool will help you create a bootable USB drive with the Windows 10 installation files.

After downloading the tool, save it to a convenient location on your computer. This tool is essential for preparing your USB drive for the installation process.

Step 2: Run the Media Creation Tool

Run the Media Creation Tool once it’s downloaded. Choose the option that says "Create installation media for another PC."

This will allow you to create a bootable USB drive that you can use on any computer, not just the one you’re currently using.

Step 3: Choose Language, Edition, and Architecture

You’ll be prompted to select the language, edition, and architecture (32-bit or 64-bit) for Windows 10. Make sure to match these settings to your computer’s requirements.

Picking the correct settings ensures that Windows 10 will run properly on your device. If you’re unsure, most modern systems use the 64-bit architecture.

Step 4: Select USB Flash Drive

Next, choose "USB flash drive" as the media to use. Ensure that your USB drive is plugged into your computer and has at least 8GB of free space.

The tool will format the USB drive, so make sure to back up any important data stored on it before proceeding.

Step 5: Create the Bootable USB Drive

The Media Creation Tool will now download Windows 10 and create the bootable USB drive. This process might take some time, depending on your internet speed.

Once the download is complete, the tool will automatically transfer the installation files to your USB drive, making it bootable.

Step 6: Boot from the USB Drive

With the USB drive ready, restart your computer and access the BIOS or UEFI settings (usually by pressing a key like F2 or DEL during startup). Set the USB drive as the primary boot device.

This step ensures that your computer will boot from the USB drive instead of the internal hard drive, starting the Windows 10 installation process.

Step 7: Install Windows 10

Your computer will now boot from the USB drive, launching the Windows 10 installation setup. Follow the on-screen instructions to complete the installation.

You’ll be asked to select your language, time, and keyboard preferences, and then you’ll proceed to install Windows 10 on your chosen drive.

After completing these steps, your computer will restart, and the initial setup of Windows 10 will begin. You’ll go through some personalization settings, and then you’ll be brought to your new Windows 10 desktop!
