Steps on how to reinstall Windows from USB

Step 1: Create a bootable USB drive

The first step is to create a bootable USB drive that contains the Windows operating system files for installation. You can use various software to create a bootable USB drive, but the most commonly used one is the Windows USB/DVD Download Tool. First, download it from the Microsoft website, install it, and follow the instructions to create a bootable USB drive.

Step 2: Backup essential files

Reinstalling the Windows operating system will erase all your data and programs, so it’s important to back up any essential files, photos, or documents you don’t want to lose. You can back up your data using an external hard drive, cloud storage services, or copying it to another computer.

Step 3: Boot from the USB drive

Insert the USB drive into your computer, restart your computer, and enter the boot menu by pressing a specific key on your keyboard (usually F2 or F12). Select the bootable USB drive option from the boot menu and click Enter.

Step 4: Select language and time format

Once the Windows installation setup starts, select your language, time format, and keyboard preferences, then click the Next button.

Step 5: Enter Windows product key

Enter your Windows product key when prompted. If you have installed Windows before and have a product key, enter it; if you don’t have a product key, click “I don’t have a product key.”

Step 6: Accept the license terms

You can choose to read through the license terms or choose to agree to the terms before proceeding with the installation.

Step 7: Choose the type of Windows installation

In this step, choose the type of installation you want. You can choose between a custom or upgrade install. The custom install will erase everything on your hard drive, while the upgrade option keeps personal files and folders.

Step 8: Select the hard drive where to install Windows

Select the hard drive where you want to install the Windows operating system. You can choose the available hard drive or partition your hard drive to install the operating system.

Step 9: Start the installation process

Once you have selected the hard drive, click the “Install” button to start the installation process. The installation process can take between 20-30 minutes, depending on your computer’s speed. Wait until it completes.

Step 10: Set your username and password

Set your username and password for the Windows operating system login. You can also use your Microsoft account for sign-in.

Step 11: Install essential drivers and updates

After installing Windows, install essential drivers like graphics, audio, and network drivers. Download the drivers from the manufacturer’s website and install them. You can also download the important updates for your Windows operating system.

Step 12: Install your essential programs

Finally, install your essential programs like an antivirus, media player, browser, and Microsoft Office. Doing so will help to keep your computer safe and running smoothly.


The above steps are quite straightforward, and everyone can do it. However, here are a few things you need to know before performing a fresh installation of Windows.

First, ensure that your computer has sufficient storage space to download and install Windows. You need at least 16GB of space on the hard drive to install the operating system. Moreover, ensure that you have a reliable internet connection to download the necessary updates and drivers during the installation process.

Secondly, ensure that you have your Windows product key before starting the installation process. If you don’t have it, you can purchase one from Microsoft or use Windows without activating it.

Finally, back up all your essential files and documents to avoid losing them during the reinstallation process.
