HOW TO<br />

Install Windows on an external hard drive<br />

USB 3.1 can make it almost as fast as an internal drive. Samuel Axon shows how<br />

Thanks to the speed of USB 3.1 and USB-C connections, it’s now<br />

possible for an external hard drive to match the read and write<br />

speeds of an internal drive. Combine that with a proliferation<br />

of external SSDs, and for the first time running Windows off an<br />

external drive is viable.<br />

Before we start, let’s get the bad news out of the way: Windows<br />

will refuse to install on an external drive if it knows that’s what<br />

you’re doing. But there are a few ways around this, including<br />

emulation via tools such as VMware. The easiest workaround is<br />

an application called WinToUSB (tinyurl.com/oaqx29q).<br />

WinToUSB serves the same function as Windows To Go,<br />

an enterprise-only tool from Microsoft that doesn’t work with<br />

most consumer versions of Windows. It’s intended for use with<br />

USB sticks, but it will work for other external drives too.<br />

If you already have a DVD, an image file or an installation<br />

USB stick for Windows, you’re set on this one. If not, it’s easy<br />

to download a Windows 10 installer ISO image file directly from<br />

Microsoft. Just make sure you pick the image for the edition and<br />

language of Windows for which you own a license. If you’re just<br />

cloning your current Windows installation, skip this step.<br />

Tell WinToUSB where Windows is<br />

The icons along the left of WinToUSB let you choose the<br />

media from which to install Windows: an image file, DVD,<br />

or clone of the current system installation. Pick the one<br />

that applies.<br />
