Installing Windows 10 from a USB drive is a fundamental skill for any tech enthusiast, system administrator, or individual looking to upgrade or perform a clean installation of Microsoft’s flagship operating system. This method offers flexibility, speed, and bypasses the need for a physical DVD drive, which is increasingly becoming obsolete. This guide will walk you through the entire process, from preparing your USB drive to booting from it and completing the installation.
Preparing Your USB Drive and Downloading the Media Creation Tool
Before you can begin installing Windows 10, you need to create a bootable USB drive. This involves downloading a tool from Microsoft and using it to prepare a USB flash drive with the necessary Windows 10 installation files.

System Requirements for the USB Drive
- Capacity: A USB flash drive with at least 8GB of storage space is recommended. While some older versions might fit on smaller drives, 8GB is the standard requirement for current Windows 10 installation media.
- Data Loss: Be aware that the process of creating a bootable USB drive will erase all existing data on the drive. Ensure you have backed up any important files before proceeding.
- USB 3.0 or Higher (Recommended): While a USB 2.0 drive will work, using a USB 3.0 or a newer version will significantly speed up both the creation of the bootable media and the subsequent installation process.
Downloading the Windows 10 Media Creation Tool
Microsoft provides a dedicated tool, the Media Creation Tool, to facilitate the creation of Windows 10 installation media. This tool allows you to download the latest version of Windows 10 and create either a bootable USB drive or an ISO file for later use.
- Navigate to the Official Microsoft Download Page: Open your web browser and go to the official Microsoft Windows 10 download page. You can typically find this by searching “Download Windows 10” on a search engine, ensuring you select a link from
microsoft.com. - Download the Media Creation Tool: On the download page, you will see a button to “Download tool now.” Click this button to download the
MediaCreationTool.exefile. - Run the Tool: Once the download is complete, locate the downloaded file and double-click it to run the Media Creation Tool. You may need administrator privileges to execute the program.
- Accept License Terms: The tool will begin by checking for updates. After a brief period, you will be presented with the license terms. Read through them and click “Accept” to proceed.
- Choose “Create installation media (USB flash drive, DVD, or ISO file) for another PC”: On the “What do you want to do?” screen, select the option to create installation media for another PC. This is crucial for creating a bootable drive that you can use on any computer. Click “Next.”
Configuring and Creating the Bootable USB Drive

-
Completion: When the process is finished, you will see a message stating “Your USB flash drive is ready.” Click “Finish.” Your bootable Windows 10 USB drive is now prepared.
Booting from the USB Drive and Starting the Installation
With your bootable USB drive ready, the next step is to configure your computer to boot from it, initiating the Windows 10 installation process.
Accessing the BIOS/UEFI Settings
To boot from a USB drive, you need to tell your computer’s firmware (BIOS or UEFI) to prioritize the USB drive over your hard drive for booting. This is done by accessing the BIOS/UEFI settings during the startup sequence.
- Insert the USB Drive: Plug the prepared Windows 10 USB drive into a USB port on the computer where you want to install Windows 10.
- Restart or Turn On the Computer: Turn on your computer or restart it if it’s already on.
- Enter BIOS/UEFI Setup: Immediately after powering on, you will see a manufacturer logo and a message indicating which key to press to enter Setup, BIOS, or UEFI. Common keys include
Del,F2,F10,F12, orEsc. You may need to press this key repeatedly as soon as the computer starts. If you miss the window, restart and try again.- Finding the Right Key: If you’re unsure of the key, consult your computer’s motherboard manual or search online for your specific computer model’s BIOS/UEFI key.
Configuring the Boot Order
Once you are in the BIOS/UEFI setup utility, you need to find the boot order or boot priority settings. The exact location varies greatly between manufacturers and BIOS/UEFI versions.
- Locate Boot Settings: Look for sections labeled “Boot,” “Boot Order,” “Boot Priority,” or “Advanced BIOS Features.”
- Prioritize the USB Drive: Within the boot settings, you will see a list of bootable devices. You need to move your USB drive to the top of this list.
- USB Device Name: The USB drive might be listed by its brand name (e.g., “Kingston DataTraveler,” “SanDisk Cruzer”) or as a generic “USB HDD,” “Removable Device,” or “UEFI USB Device.”
- Navigation: Use the arrow keys on your keyboard to navigate. Keys like
+and-,Page Up/Page Down, or specific function keys (often indicated on the screen) are used to change the order.
- Save Changes and Exit: Once the USB drive is set as the first boot device, navigate to the “Exit” or “Save & Exit” section of the BIOS/UEFI. Select the option to “Save Changes and Exit” (often mapped to
F10). Confirm your choice when prompted.
Starting the Windows 10 Setup

If you have correctly configured the boot order, your computer will now attempt to boot from the USB drive.
- Boot Device Prompt (Optional): Some computers display a “Press any key to boot from USB…” message shortly after restarting. If you see this, press any key on your keyboard to proceed.
- Windows Setup Loading: You should now see the Windows logo and a loading spinner, indicating that the Windows 10 setup files are being loaded from the USB drive.
