Ubuntu 12.04 LTS ，制作一个USB的启动盘。
This is a Windows program for saving and restoring images from removable drives (USB drives, SD Memory cards, etc). It can be used to write boot images (i.e. ubuntu-12.04-preinstalled-desktop-armhf+omap4.img) to a SD Flash device or USB flash device, making it bootable. It currently does not support writing an ISO image to usb.
This program and source code can be downloaded from here.
使用的软件是win32-image-writer，Win32 disk imager(又名Image Writer for Windows)是一款用来将 .img 文件写入U盘的软件。
