Those days are no more when we were only run Windows from the hard drive inside your computer. Now, you can install and run Windows operating system from your USB disk too. If you want to carry your Windows PC, then just carry your USB disk, not the whole desktop PC or laptop. If you want, Windows 10/8/7 can be powered up from a USB stick or a USB hard drive, it is now possible. Once the hardware and software are available, everything will work fine.


Over the internet, there are many software’ are available for running Windows OS via a USB flash drive. However, today we’re going to talk about a software called WinToUSB. I am not sure it is the best, but yes it will fulfill your need.

Before proceeding the steps, first, download the WinToUSB from the official website (size approx 5-megabytes). Make sure you have a Windows ISO file on the computer’s hard drive or on a CD.

For installing Windows OS on your PC, you should at least 32GB capacity USB drive. Now, connect your USB disk to PC, and if you have the ISO on the hard drive, click on the icon on the left that says, “ISO.” After that, click on the small icon beside the search box to locate the ISO image. If everything goes according to plan, the Windows ISO should pop up under the Operating System category. From there, click on the “Next” button below.

Since you’re installing the operating system on a USB stick, it will take some time to complete, depending on the speed of USB disk.

If you have CD / DVD instead of an ISO file, the just follow the same procedure, but this time, click on the CD-ROM icon instead of the ISO icon.

And what about the third Icon? If you’re interested in cloning your current installed operating system, then this is the Clone icon you’ll be required to click on.
