Creating a bootable USB drive for Windows 10 requires a Windows computer, a USB drive with at least 8GB of free space, and an internet connection. The process involves downloading the Windows 10 Media Creation Tool from the official Microsoft website, launching it, accepting the terms of service, selecting "Create installation media (USB flash drive, DVD, or ISO file) for another PC," choosing language, edition, and architecture, selecting "USB flash drive," picking the USB drive from the list, and clicking Next until the download is complete. After downloading, to boot from the USB drive, restart the device and enter the boot menu by pressing the appropriate key (F11, F12, Esc, or Delete) to select the USB drive.
