Creating the drive is only half the task; the computer must be instructed to start from the USB drive rather than its internal hard drive. This requires modifying the boot order. First, insert the USB drive into the target computer and restart it.

Installing Windows from a flash drive is not only faster and more reliable than using a DVD, but it is also an environmentally friendly and efficient method that puts the power of system recovery directly into the hands of the user. This essay provides a comprehensive guide to creating a bootable Windows USB drive and using it to perform a clean installation of the operating system.
