Windows is sold in the form of DVDs and downloadable ISOs. The Windows DVD can be put into an optical drive for easy installation. However, with the advent of ultra portable devices and tablets that do not have optical drives, installing Windows from the setup DVD becomes a problem. The only solution for these devices is to install Windows from a USB device such as a flash drive.There are many other reasons why despite having an optical drive, you might want a bootable USB device for installing Windows. One is that installing Windows from a flash drive is a lot faster than that from a DVD. Creating a flash drive for installing Windows is not as simple as copying the setup files to it as it will not be bootable. To make it bootable, you need to use special software.

Also, you need to make sure that you have an ISO file of the Windows setup DVD with you.
