WinToFlash is a free tool to make a bootable USB device from your Windows installation CDs or DVDs. WinToFlash is very simple and easy to use and no installation is required that means no real technical knowledge is necessary. WinToFlash works well with LiveCDs as well.
Simply download WinToFlash zip file from here and extract it to a directory on your hard disk. Once extracted, double-click and run the WinToFlash.exe binary and you can choose the advanced option to choose the OS CD or DVD type or simply choose the wizard mode. Make sure you have a USB disk or drive with enough space on it.
While the default settings are good enough, you can always choose to change from “Settings – Options” menu item.
