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.
- 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.
- Windows installation disk or Windows installation files stored somewhere on your computer.
Steps to create a bootable USB Flash Drive
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 also supports Windows 8 and Windows 8.1. To avoid this tutorial from getting outdated, I would advise to download the software from the link provided if you are not planning on using Windows 8 or 8.1.
- Extract the downloaded zip file to any folder on your desktop.
- Open the folder and run WintoFlash.exe by double clicking on it.
- Click Next, check I accept EULA, click Next and Next again. Wait for the software to load some ads, click Next and Next again.
- A welcome screen like one in the image below will show up.
- Click on the big green tick. The welcome screen will turn translucent and WinToFlash wizard will open.
- Click Next. On Windows File path entry box, click Select button and select the location of your Windows disk, or the folder containing the Windows setup files and click OK.
- On USB Drive path entry box, select your USB flash drive's location and click OK.
- Click Next button. In the dialog box, encircle I accepted the license agreement and click Continue.
- A warning message will be displayed saying that "Formatting will erase all data on the disk". Click OK on the message.
- WintoFlash will show a window with a progress bar like the one in the image below.
- 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.
Update: WinToFlash website is no longer available; meaning the software is not supported anymore. You can try Rufus to install almost any OS from a USB drive.
