Install, Boot Windows from USB Pen, Thumb or Flash Drive

Normally, Windows is installed using optical media like DVDs and CDs but there are times when it is not possible to boot into the windows setup using disks probably because your DVD drive is not working or, if you are using one of those ultra-portable laptops, it is not there at all.

Install Windows from USB drive
To overcome this problem, one can either use an external DVD drive and install Windows normally or create a bootable pen drive to install Windows whenever needed. In this tutorial, we will discuss about the latter and learn how can we create a bootable USB drive for installing Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 8.1. As installing Windows from a flash drive is much faster than from a CD/ DVD, such an installation will also save time.

This article assumes that your computer has a mother board which supports booting from USB drives. Most modern laptops and desktops support it. If you have bought your computer in the last 5 years, you do not need to worry about this.

Installation Requirements
  1. An empty flash drive with a storage capacity of 1GB for Windows XP and 3GB for Windows 8.1, Windows 8, Windows 7, Windows Vista and Windows Server 2008.
  2. Windows installation disk or Windows installation files stored somewhere on your computer.

Steps to create a bootable USB Flash Drive

  1. Download Win to Flash. The software is still in beta phase so it is possible that it has some bugs although I have personally faced none. The latest version of Win to Flash can be downloaded from the Win to Flash website. The latest version also supports Windows 8 and Windows 8.1. To avoid this tutorial from getting outdated, I would advise to download the software from the former link if you are not planning on using Windows 8 or 8.1.
  2. Extract the downloaded zip file to any folder on your desktop. 
  3. Open the folder and run WintoFlash.exe by double clicking on it.
  4. Click Next, check I accept EULA, click Next and Next again. Wait for the software to load some ads, click Next and Next again. 
  5. A welcome screen like one in the image below will show up.
  6. Boot Windows USB Flash Drive

  10. On USB Drive path entry box, select your USB flash drive's location and click OK.
  11. Click Next button. In the dialog box, encircle I accepted the license agreement and click Continue.
  12. A warning message will be displayed saying that "Formatting will erase all data on the disk". Click OK on the message.
  13. WintoFlash will show a window with a progress bar like the one in the image below.
  14. Boot Windows from USB

  15. After the progress bar reaches the end, press Next and then press Exit. A notification to update WintoFlash might be shown, click "No just close" to close it.
That's it. You now have a bootable pen drive that can be used to install Windows. To install Windows from it, follow the steps given below:-

Installing Windows from the bootable USB Thumb Drive

  1. Plugin your thumb drive.
  2. Start your computer. Go into the BIOS setup by pressing the Delete key. In the boot menu, select your flash drive as the first boot device. Save settings and restart your PC. (This step might be different for different computers. Check your system guide to know how to change the boot order in your PC.)
  3. Windows setup will load.
  4. Install Windows by following the on-screen instructions.
This tutorial works on all versions of Windows including Windows 8.1, Windows 8, Windows 7, Windows XP and Windows Vista.
