How to Install Windows 10 from USB Drive: 2025 Step-by-Step Guide

Hey guys! Upgrading or doing a fresh install of Windows 10? Using a USB drive is the way to go! It's faster and more reliable than using a DVD. In this guide, I'll walk you through everything you need to know to install Windows 10 from a USB drive in 2025. Let's dive in!

What You Need

Before we get started, make sure you have everything on this list:

A USB Drive: At least 8GB in size. Make sure it's empty, as the process will erase everything on it.
Windows 10 ISO File: You can download this directly from Microsoft.
A Computer: To create the bootable USB drive.
Your Windows 10 Product Key: If you're upgrading, you might already have a digital license. If not, make sure you have your product key handy.
Stable Internet Connection: For downloading the ISO and any necessary tools.

Having these items ready will make the process much smoother, and you'll be less likely to run into snags along the way. Trust me, being prepared saves a lot of headache later!

Step 1: Download the Windows 10 ISO File

First things first, you need to grab the Windows 10 ISO file. Head over to the Microsoft website. Navigate to the section where you can download the Media Creation Tool. This tool is your best friend for getting a genuine ISO file straight from the source. Once you've downloaded the Media Creation Tool, run it. Follow the prompts, and when asked, choose "Create installation media for another PC." Then, select the ISO file option. Make sure to select the correct architecture (usually 64-bit these days unless you have a very old machine). Choose a location on your computer to save the ISO file. The download might take a while depending on your internet speed, so grab a coffee and be patient. Once the download is complete, you're ready to move on to the next step.

This part is super important to get right because you want a clean, official version of Windows 10. Using unofficial sources can lead to all sorts of problems, like malware or an unstable system. So, stick with Microsoft's tool for the best results. Keep in mind that Microsoft frequently updates the Media Creation Tool to provide the latest version of Windows 10, so you'll always have the most current features and security updates when you use this method. Remember to double-check your internet connection during the download to avoid any corrupted files, which can cause installation errors later on.

Step 2: Create a Bootable USB Drive

Now that you have the ISO file, let's make that USB drive bootable. Download and install Rufus. Rufus is a small, free, and incredibly useful tool for creating bootable USB drives. Once Rufus is installed, launch it. Insert your USB drive into your computer. In the Rufus interface, select your USB drive from the "Device" dropdown menu. Click the "Select" button next to the "Boot selection" dropdown, and navigate to the Windows 10 ISO file you downloaded earlier. Choose "Standard Windows installation" under "Image option". Ensure that the "Partition scheme" is set to "MBR" if you're using an older BIOS-based system, or "GPT" if you're using a newer UEFI-based system. If you're not sure, you can usually find this information in your computer's BIOS settings. Leave the "File system" as "NTFS." Click the "Start" button. Rufus will warn you that all data on the USB drive will be erased. Confirm to proceed. Wait for Rufus to finish creating the bootable USB drive. This might take a few minutes. Once it's done, you're all set to install Windows 10!

Creating a bootable USB drive might seem a bit technical, but Rufus makes it incredibly straightforward. It's essential to choose the correct partition scheme (MBR or GPT) because this determines how your computer will boot from the USB drive. If you select the wrong scheme, your computer might not recognize the USB drive as a bootable device. Also, remember to back up any important data from the USB drive before you start, as the process will wipe everything clean. Keep an eye on the progress bar in Rufus, and don't interrupt the process until it's finished. A corrupted bootable USB drive can cause installation problems, so it's best to let Rufus do its thing without interruption. Once the process is complete, you can safely remove the USB drive and proceed to the next step. This bootable USB drive is your key to installing Windows 10 on your computer.

Step 3: Boot from the USB Drive

Alright, time to boot from that USB drive we just created! Restart your computer. As your computer restarts, you'll need to enter the BIOS or UEFI settings. This usually involves pressing a specific key during startup, such as Delete, F2, F12, or Esc. The key varies depending on your computer manufacturer, so check your computer's manual or look for a prompt on the screen during startup. Once you're in the BIOS/UEFI settings, look for the boot order or boot priority options. Change the boot order to prioritize the USB drive. This tells your computer to boot from the USB drive instead of the hard drive. Save the changes and exit the BIOS/UEFI settings. Your computer will restart, and if everything is set up correctly, it should boot from the USB drive. You'll know you're on the right track when you see the Windows logo or the Windows installation screen. If your computer boots back into the existing operating system, you might need to revisit the BIOS/UEFI settings and double-check the boot order.

Booting from the USB drive is a crucial step, and it can be a bit tricky if you're not familiar with BIOS or UEFI settings. Remember to consult your computer's manual or search online for specific instructions for your model. The key to enter the BIOS/UEFI settings can vary widely, so it's essential to get it right. Once you're in the settings, be careful not to change any other options unless you know what you're doing. Incorrect settings can cause your computer to malfunction. The boot order is usually listed in the "Boot" section of the BIOS/UEFI settings. Make sure the USB drive is listed as the first boot device. Save the changes and exit. If your computer still doesn't boot from the USB drive, try unplugging any other USB devices that might be interfering with the boot process. This step is all about getting your computer to recognize and boot from the bootable USB drive, which will then launch the Windows 10 installation.

Step 4: Install Windows 10

Now for the main event – installing Windows 10! Once your computer boots from the USB drive, the Windows 10 installation process will begin. You'll be greeted with a setup screen where you can choose your language, time zone, and keyboard layout. Select your preferences and click "Next." On the next screen, click "Install now." You'll be prompted to enter your product key. If you're reinstalling Windows 10 on a computer that already had it activated, you can usually skip this step by clicking "I don't have a product key." Windows 10 will automatically activate once it's installed. Accept the license terms and click "Next." You'll be asked what type of installation you want. Choose "Custom: Install Windows only (advanced)." This option gives you more control over the installation process. On the next screen, you'll see a list of drives and partitions. If you're doing a clean install, you might want to delete all existing partitions on the drive where you want to install Windows 10. This will ensure a clean slate. Select the unallocated space and click "New" to create a new partition. Choose the size of the partition and click "Apply." Select the partition you just created and click "Next" to begin the installation process. Windows 10 will now be installed on your computer. This might take a while, so be patient. Your computer will restart several times during the installation process.

Installing Windows 10 is a straightforward process, but it's essential to pay attention to the details. The "Custom" installation option is recommended because it allows you to manage your partitions and ensure a clean install. Deleting existing partitions will erase all data on those partitions, so be absolutely sure you've backed up anything important before proceeding. When creating a new partition, you can choose to create multiple partitions if you want to separate your operating system from your data. However, for most users, a single partition is sufficient. During the installation process, your computer will restart several times. Don't be alarmed – this is normal. Just let the process run its course without interruption. Once the installation is complete, Windows 10 will boot up, and you'll be guided through the initial setup process, such as creating a user account and configuring your settings. This entire process leads to a fresh installation of Windows 10.

Step 5: Complete the Setup

After Windows 10 is installed, you'll need to complete the initial setup. This involves a few steps: Select your region and language. Choose your keyboard layout. Connect to a Wi-Fi network (if available). Create a user account and set a password. Configure your privacy settings. Choose whether to use Cortana, Microsoft's virtual assistant. Once you've completed these steps, you'll be taken to the Windows 10 desktop. Congratulations, you've successfully installed Windows 10 from a USB drive! Now, it's a good idea to install the latest drivers for your hardware. You can usually find these on the manufacturer's website. Also, make sure to run Windows Update to install any available updates and security patches.

Completing the setup is the final step in the installation process. It's essential to choose the right settings for your region, language, and keyboard layout. Connecting to a Wi-Fi network will allow you to download updates and install drivers. Creating a strong password for your user account is crucial for security. Take some time to review the privacy settings and choose the options that you're comfortable with. Cortana can be a useful tool, but it's up to you whether you want to use it. Once you're on the desktop, installing the latest drivers is essential for ensuring that your hardware is working correctly. Running Windows Update will keep your system up-to-date with the latest security patches and bug fixes. With these final steps completed, you can enjoy your fresh installation of Windows 10. This final stage completes your journey to a fully functional Windows 10 system.
