Windows 11 Bootable USB: Unlike a regular USB drive for storing files, a bootable USB is specially prepared with a bootable image file (like an ISO) and a bootloader, allowing the computer to recognize it as a bootable device during startup. This makes it a versatile tool for installing new operating systems, running live environments, or recovering a non-functional system.
