Creating a bootable USB drive is the most common and practical use of a Windows ISO today, as most modern computers lack DVD drives. The process, while simple, requires precision. Simply copying the ISO file to a USB drive will not work; the drive must be made "bootable." Microsoft provides a free tool called the , but the industry standard is a free, open-source utility named Rufus . With a few clicks, Rufus writes the contents of the ISO to the USB drive, partitions it correctly, and makes it bootable. Once prepared, you insert the drive, restart the computer, and press a key (usually F12, ESC, or Del) to access the boot menu and select the USB drive.
