How to install Windows® 7 from a USB?
With the release of Windows 7, you must be thinking to migrate your existing operating system to the Microsoft newest operating system. Microsoft Windows 7 offers several new features that make your computer significantly easier and faster to use than earlier versions of Windows.
Windows 7 makes it easier to use the Start menu, open files and programs, find information, and accomplish other common tasks, such as send and receive secure email, surfing the Internet securely, scan and view pictures, play music and videos, and change settings.
Windows 7 installation is not very difficult, all you need is just a DVD-ROM and an installation disc. However, if your DVD-ROM is out of order or you don’t have one then you can install Windows 7 through a USB drive. When you’ll install Windows 7 from a USB drive, it will take less time compare to DVD-ROM.
The method is very easy but your motherboard must support USB Boot feature to make use of the bootable USB drive.
Requirements: USB Flash Drive (Minimum 4GB),
Windows 7 installation files.
