#1. Requirements for Installing Windows 10 from USB

Before proceeding with the installation, make sure you have the following:

A minimum of 8GB is required, but 16GB or more is recommended for a smoother process.

2. Windows 10 ISO File

Download the latest official Windows 10 ISO from the Microsoft website to ensure a secure installation.

#2. Create a Bootable USB Drive Using the Windows 10 ISO

To install Windows 10 from a USB, you’ll first need to download the ISO file and then use a tool to create the bootable drive. Here’s a step-by-step guide:

Step 1: Go to the official Microsoft Windows 10 download page using any modern web browser.

Step 2: If you’re on a Windows PC, click “Download Tool Now” to get the Media Creation Tool, or scroll further down and select “Download ISO” for a direct ISO download if you’re using Rufus or a non-Windows device.

Step 3: Follow the on-screen instructions to download and save the ISO file to your local drive, which will be used later to create the bootable USB.

Step 4: Once you’ve downloaded the ISO file, use one of the following tools to write it to a USB flash drive:

Option A: Windows Media Creation Tool (Recommended for Most Users)

• Launch the Media Creation Tool, then choose “Create installation media (USB flash drive, DVD, or ISO file) for another PC” and click Next.
• Select your preferred language, Windows edition, and system architecture (32-bit, 64-bit, or both), then click Next.
• Choose USB flash drive as the media type, select your connected USB device, and follow the prompts to create the bootable installer.

Option B: Rufus (Recommended for Advanced Users)

• Download and open Rufus from rufus.ie, then insert your USB drive and select it under the Device dropdown.
• Click Select to load the Windows 10 ISO, then choose the correct Partition Scheme — GPT for UEFI or MBR for legacy BIOS systems.
• Keep the default settings for File System (FAT32) and Cluster Size, click Start, confirm any prompts, and wait for Rufus to complete the bootable USB.

#3. Change BIOS/UEFI Settings to Boot from USB

Step 2: Within the BIOS/UEFI interface, find the Boot or Boot Order section using the keyboard arrows or mouse, depending on your system’s controls.

Step 3: Find the Boot Priority or Boot Device Order list and move your USB drive to the top position to ensure the system boots from the USB first.

Step 4: Save your changes—usually by pressing F10 and confirming with Yes—then exit the BIOS/UEFI setup to restart your computer and boot from the USB drive.

#4. Install Windows 10 from the USB Drive

Step 1: Restart your computer with the bootable USB drive inserted, and if necessary, press the designated key (like F12 or ESC) during startup to open the boot menu and select the USB drive as the boot source.

Step 2: When the Windows Setup screen appears, select your preferred language, time zone, and keyboard layout, then click “Next” to proceed to the next screen. On the next screen, click “Install Now” to start the Windows installation process.

Step 3: Choose the installation type: select “Upgrade” to keep your existing files and apps, or “Custom” for a clean install that may require deleting existing partitions before continuing.

Step 4: After selecting the target partition, the system will begin installing Windows 10, during which your computer will restart several times without requiring user input.
