Install Windows 7 from USB (How To)

Nowadays, many computer manufacturers, build their computer models (commonly laptops) without including an optical disk drive with them in order to accomplish a smaller – in dimensions – product or for cost reasons. But this becomes a problem in some cases, e.g. when you want to re-install the operating system or you want to upgrade it to another version you purchased. For such cases you have to create a bootable USB disk to accomplish that task.

This tutorial was written for all users that their computer doesn’t include an optical disk drive (or the optical disk drive is damaged) or they want to install Windows 7 from a USB. *

* Note: This guide works for creating a Windows USB bootable disk for all Windows versions (8, 7, Vista & XP). The only thing needed is to have the corresponding Windows version stored in a ISO image file.
