This section explains how to create a bootable Emergency Recovery USB device (ERD) using Microsoft Windows Preinstallation Environment (Windows PE). When it is booted, the ERD provides access to the Emergency Recovery application you can use to perform recovery operations on a device.
You must perform the following steps on a Windows 7 or Windows Vista device. The steps are not supported on Windows XP. The USB drive size must be at least 256 MB.
Complete Step 1 through Step 6 in Section 5.2, Creating a Windows PE ERD to create the ERD ISO image. Make sure you also complete the prerequisites listed for the steps.
At a command prompt on a Windows 7 or Windows Vista, enter diskpart to start the DiskPart utility used to prepare the USB device.
At the DISKPART prompt, enter each of the following commands, one at a time. Press Enter after each command.

For example:
xcopy c:\winpe\iso\*.* f:\ /e/h/f
The USB drive is ready to use as an ERD.
