Windows PE USB Boot

Microsoft Windows PE is an operating system which can boot to command line from harddisk, USB disk, network or CD.

Windows PE is typically used for system maintenance. Another usage can be data recovery, where you as example boot Windows PE to a CD and copy files to a USB disk using data recovery programs.

Windows PE version 3.0 is available as part of "The Windows® Automated Installation Kit (AIK) for Windows® 7". The current download is in the file "KB3AIK_EN.iso", 1,789,542,400 bytes, date published 8/6/2009, SHA1 793F4CC4741EBAD223938BE0EEEE708EDA968DAA.

The user has to build the Windows PE boot media following instructions in the documentation. As example a bootable iso image is not included.

Windows PE can boot from a USB disk if the BIOS supports USB boot, but only in Windows PE ram disk mode. For BIOS versions from before about 2006 you have to know how. If not, you will get the error message:

"An error occurred while attempting to read the boot configuration data."
