How to Make Bootable Flash Drive
A bootable flash drive is a flash drive that boots up when you start your system. Having a bootable flash drive comes in handy if you ever want to install an operating system on your flash drive to use for emergency purposes. While the process for making your flash drive bootable is complex, it is doable if you carefully follow a few steps.
Instructions
1
Download and install Microsoft's "Windows 7 USB/DVD Download Too.l" This program's sole purpose is to copy Windows installation files to a flash drive and then make it bootable. Once the flash drive is bootable, it can both install Windows and repair existing Windows installations.
2
Run the tool and click the "Browse" button to open a standard file-selection menu. Navigate to your Windows 7 Installation ISO and double-click it. The ISO is an exact replica of the contents of the Windows 7 DVD. If you purchased Windows 7 online, the ISO is the file you downloaded. If you purchased Windows 7 from a store, you will first need to create an ISO of your Windows 7 DVD using a disc-authoring program like CloneDVD, MagicISO or Daemon Tools, all available for free online
