Hey guys! Upgrading or reinstalling your operating system might sound like a daunting task, but trust me, it's totally manageable, especially when you're using a USB drive. This guide is going to walk you through how to install Windows 10 from a USB drive in 2025. We'll cover everything from creating a bootable USB to tweaking your BIOS settings, so you can breathe new life into your PC or set up a fresh install without a hitch. Let's dive in!

What You'll Need

Before we get started, let's make sure you have all the essentials. You'll need:

  • A USB Drive: Aim for at least an 8GB USB drive. Make sure it's empty, as the process will erase everything on it.
  • Windows 10 ISO File: You can download this directly from Microsoft’s website. Just search for "Download Windows 10 ISO" and follow the instructions.
  • A Computer: This is the computer you'll be installing Windows 10 on. Obviously!
  • Internet Connection: You'll need this to download the necessary tools and the ISO file.
  • Rufus or Windows USB/DVD Download Tool: These tools will help you create a bootable USB drive. Rufus is generally faster and more reliable, but the Windows tool is also a solid option.
  • Your Windows Product Key: Keep this handy. You'll need it during the installation process.

Having these items ready will make the whole process smoother and less stressful. Nobody wants to be scrambling for a product key halfway through the installation!

Creating a Bootable USB Drive

Now that you’ve gathered your gear, let’s get that USB drive ready to boot. This involves formatting the drive and copying the Windows 10 installation files onto it. Here's how to do it using Rufus, which is generally considered the easiest and fastest method:

  1. Download Rufus: Head over to the official Rufus website (rufus.ie) and download the latest version.
  2. Launch Rufus: Once downloaded, run the Rufus executable. You usually don’t need to install it; it runs directly.
  3. Select Your USB Drive: In the Rufus interface, make sure your USB drive is correctly detected in the “Device” dropdown menu. If you have multiple USB drives connected, double-check you’ve selected the right one!
  4. Choose Boot Selection:
    • Click the “Select” button next to the “Boot selection” dropdown.
    • Navigate to where you saved the Windows 10 ISO file and select it.
  5. Configure Settings:
    • Partition scheme: Usually, Rufus will automatically detect the correct partition scheme (either MBR or GPT) based on your system. If you're unsure, leave it at the default. You can usually determine this in your computer's BIOS settings.
    • Target system: This should match your partition scheme. If you selected MBR, it will likely be “BIOS or UEFI.” If you selected GPT, it will be “UEFI.”
    • Volume label: You can give your USB drive a name, like “Windows10.”
    • File system: Choose “NTFS” as the file system. This is the standard for Windows installations.
    • Cluster size: Leave this at the default setting.
  6. Start the Process: Click the “Start” button. Rufus will warn you that all data on the USB drive will be erased. Confirm that you've backed up any important files, and click “OK” to proceed.
  7. Wait for Completion: Rufus will now format the USB drive and copy the Windows 10 installation files onto it. This process might take anywhere from 10 to 30 minutes, depending on the speed of your USB drive and computer.
  8. Close Rufus: Once the process is complete, Rufus will display a “Ready” status. You can now close Rufus.

Congratulations! You’ve just created a bootable USB drive. This USB drive will be your key to installing Windows 10 on your computer. Remember to keep it safe and label it clearly so you don’t accidentally overwrite it later.

Adjusting Your BIOS Settings

Before you can boot from the USB drive, you’ll need to adjust your computer’s BIOS settings. The BIOS (Basic Input/Output System) is a firmware that initializes your hardware and starts the operating system. You'll need to tell the BIOS to boot from the USB drive instead of your hard drive. Here’s how:

  1. Restart Your Computer: Shut down your computer completely and then power it back on.
  2. Enter BIOS Setup: As your computer starts, you'll need to press a specific key to enter the BIOS setup. This key varies depending on the manufacturer, but it’s often one of the following: F2, Delete, F12, Esc, or F10. Watch the startup screen closely; it usually displays a message like “Press DEL to enter setup.”
  3. Navigate to Boot Options: Once you’re in the BIOS setup, use the arrow keys to navigate to the “Boot” options. The exact wording and layout will vary depending on your BIOS version.
  4. Change Boot Order: Look for a setting called “Boot Order,” “Boot Priority,” or something similar. You need to change the order so that your USB drive is listed as the first boot device. Use the arrow keys to select your USB drive and then press the “+” or “-” keys to move it to the top of the list.
  5. Disable Secure Boot (If Necessary): Some systems have a feature called “Secure Boot” that prevents booting from unsigned media, which might include your USB drive. If you encounter issues booting from the USB, you might need to disable Secure Boot. Look for a “Secure Boot” option in the BIOS settings (often under the “Security” or “Boot” tabs) and set it to “Disabled.”
  6. Save and Exit: Once you’ve adjusted the boot order and disabled Secure Boot (if necessary), press the key indicated on the screen to save your changes and exit the BIOS setup. This is usually F10. Confirm that you want to save the changes and exit.

Your computer will now restart and attempt to boot from the USB drive. If everything is set up correctly, you should see the Windows 10 installation process begin.

Installing Windows 10

With your bootable USB drive created and your BIOS settings tweaked, you’re now ready to install Windows 10. This part involves a series of steps that will guide you through partitioning your hard drive, selecting installation options, and activating your copy of Windows. Here’s a detailed walkthrough:

  1. Boot from USB: Ensure your computer restarts and boots from the USB drive. If it boots back into your existing operating system, double-check your BIOS settings to make sure the USB drive is the first boot device.
  2. Windows Setup: The Windows Setup screen will appear. Select your language, time and currency format, and keyboard input method. Click “Next” to continue.
  3. Start Installation: Click the “Install now” button.
  4. Enter Product Key: Enter your Windows 10 product key. If you don’t have a product key or want to skip this step, you can click “I don’t have a product key.” Keep in mind that you’ll need to activate Windows later.
  5. Select Operating System: Choose the version of Windows 10 you want to install (e.g., Windows 10 Home, Windows 10 Pro). Make sure to select the version that corresponds to your product key, if you have one. Click “Next” to continue.
  6. Accept License Terms: Read the license terms carefully, check the “I accept the license terms” box, and click “Next.”
  7. Choose Installation Type:
    • Upgrade: This option is for upgrading an existing Windows installation. It will keep your files, settings, and applications. However, it’s not recommended for a clean install or if you’re experiencing significant issues with your current system.
    • Custom: Install Windows only (advanced): This option is for a clean install. It will erase all data on your selected partition. This is the recommended option for most users who want a fresh start.
  8. Partitioning Your Hard Drive: If you chose the “Custom” installation type, you’ll need to partition your hard drive. This is where you decide how much space to allocate to the Windows installation.
    • Existing Partitions: You’ll see a list of existing partitions on your hard drive. If you want to erase everything and start fresh, select each partition and click “Delete.” Be absolutely sure you’ve backed up any important data before doing this!
    • Creating New Partitions: Once you’ve deleted the existing partitions (or if you have a new hard drive), you’ll see unallocated space. Select the unallocated space and click “New.” Enter the size of the partition you want to create (in MB). A good starting point is to allocate at least 100GB (102400 MB) for the Windows partition. Click “Apply.”
    • System Reserved Partition: Windows will create a system reserved partition for boot files. Click “OK” to allow this.
    • Select Installation Partition: Select the partition you created for the Windows installation and click “Next.”
  9. Installing Windows: Windows will now begin installing. This process might take anywhere from 15 to 45 minutes, depending on the speed of your computer. During this time, your computer will restart several times.
  10. Initial Setup: After the installation is complete, Windows will restart and guide you through the initial setup process. This includes:
    • Selecting Your Region: Choose your region and click “Yes.”
    • Selecting Your Keyboard Layout: Choose your keyboard layout and click “Yes.”
    • Adding a Second Keyboard Layout (Optional): If you want to add a second keyboard layout, click “Add layout.” Otherwise, click “Skip.”
    • Connecting to a Network: Connect to your Wi-Fi network. You can also skip this step and connect later.
    • Choosing Setup Options:
      • Personal Use: Select this option if you’re setting up the computer for personal use.
      • Organization: Select this option if you’re setting up the computer for work or school.
    • Microsoft Account: Sign in with your Microsoft account or create a new one. You can also choose to create a local account instead.
    • Creating a User Account: If you chose to create a local account, enter a username and password.
    • Privacy Settings: Review the privacy settings and choose your preferences.
  11. Welcome to Windows: After completing the initial setup, Windows will finalize the configuration and present you with the desktop.

You’ve successfully installed Windows 10 from a USB drive! Now you can install your favorite applications, restore your files from backup, and customize your system to your liking.
