How to Install Windows Server 2012 from USB Flash – ISO Image

Article Reads:51205

Most would remember the days we had to have a CDROM or DVDROM in order to proceed with the installation of an operating system. Today, it is very common installing an operating system direct from an ISO image. When dealing with virtualized systems, it becomes pretty much a necessity.

This article will show how to install Windows Server 2012 (the same process can be used for almost all other operating systems) from a USB Flash.

The only prerequisite for this process to work is that you have a USB Flash big enough to fit the ISO image and the server (or virtualization platform) supports booting from a USB Flash. If these two requirements are met, then it’s a pretty straight-forward process.
