Make the Flash Drive bootable:
Use the bootSect utility that is shipped with windows 7. To do so

- Navigate the directory where bootsect is found
F:
cd f:\boot
- Use the bootsect to make the USB drive bootable. This updates the drive with BOOTMGR compatible code and prepares it to boot Windows 7.
bootsect.exe/nt60 H:
- Close the Command prompt window.
- Copy all files from the Windows 7 DVD to the formatted Flash Drive. The safest and the fastest way would be to use the Windows Explorer. Open the Disk, select everything and drag it into your Flash Drive. This could take a few minutes to copy.
