1. What You’ll Need
USB drive : at least 8 GB (16 GB recommended). All data on it will be erased. Windows 10 ISO file or the Media Creation Tool (official Microsoft tool). A working computer (Windows, macOS, or Linux) to create the installer. Product key (optional: you can skip during install if you’ve previously activated Windows 10 on that PC).
2. Download the Official Tool or ISO Go to Microsoft’s official download page: https://www.microsoft.com/software-download/windows10 You have two options: Option A: Use the Media Creation Tool (easiest for Windows users)
Download the tool → run it → choose “Create installation media for another PC” → select language, edition, architecture (64-bit recommended).
Option B: Download ISO directly
On the same page, under “Create Windows 10 installation media”, download the tool and run it, or use a trick: change your browser’s user agent to iPad/Android to get direct ISO links. Alternatively, use a third-party tool like Rufus (more advanced).
3. Create the USB Installer On Windows (using Media Creation Tool)
Insert USB drive (backup data first). Run Media Creation Tool. Accept license → Create installation media . Choose language, edition, architecture (64-bit is standard). Select USB flash drive → pick your USB from the list. Click Next – the tool downloads Windows 10 and writes it to USB.
On Windows (using Rufus – more control)
Download Rufus (rufus.ie). Insert USB drive. Open Rufus → Device = your USB. Under Boot selection , click SELECT → choose your Windows 10 ISO. Partition scheme :
GPT if your PC has UEFI (most modern PCs). MBR for older BIOS systems.
File system: FAT32 (default for UEFI). Click START → confirm warnings → wait for completion.
