How to Install Windows 8 from a USB

Forget the CD and install Windows 8 with your flash drive 

A guide? To install Windows? Slapping a new operating system on your desktop or laptop PC should be old hat by now, right? This is Windows 8, after all: Odds are pretty good that you, an astute and well-travelled Maximum PC reader, have been around the ol’ Windows installation block a few times before.

And unlike previous versions of the operating system, Windows 8 doesn’t even need that much babysitting. Once you’ve set the installer application running, it’s off to the races: You can sit back, enjoy a nice beverage or a fun sitcom, and let Microsoft’s fantastically efficient OS installation routine do all the work. By the time your Windows 8 OS needs your input, you’re practically finished – but a few short steps, if not minutes, away from the tiled joy that is Windows 8 proper.

So, er, what does that leave us to talk about?

Plenty. Ditch your discs; we’re going to show you how to install Windows 8 from a USB key. 

Installing Windows 8 from a USB key

If you shun DVDs, love speedier installations, have a digital download of Windows 8, or just plaindon’t have an optical drive – or are too lazy to hook one up – then it’s going to be a USB-based installation for you. And that’s just fine; it’s a great, quick way to get an operating system onto your hard drive and extremely useful if you, say, keep your Windows installation disc tucked away as an .iso on your network drive instead of thrown in one of your desk drawers.

The easiest way to accomplish this process is to already have your hands on a copy of Windows 8’s downloadable .iso file – acquirable by purchasing it from Microsoft itself. If you have a flash drive of the appropriate size (at least four gigabytes or greater, depending on whatever file Microsoft lets you grab), you’re golden. Insert your flash drive into a USB slot on your system, and then go grab Microsoft’s Windows 7 USB/DVD Download Tool – don’t let the name dissuade you.

Install the app and run it. It’ll ask you to select an .iso file to be “burnt” onto your USB key. Go ahead and select your Windows 8 .iso file – the fact that it’s not the right operating system as the tool’s name has absolutely no bearing on what you’re doing. 

Yes, we know, it says "Windows 7" download tool, but you can just ignore that part.

On the next screen, you’ll be asked whether you’d like to create a “Windows 7 backup” – again, ignore the name – on a USB device or DVD. Pick the obvious answer, select your USB key from the drop-down menu.

Select your USB device

When you're ready to let 'er rip, click on "Begin copying!"  If the tool needs to format your USB key first, it'll let you know.
