You start Windows Vista from a Microsoft Windows Preinstallation Environment (Windows PE) 2.0 image by using the flat file boot method. When you do this, an access violation occurs.
This problem occurs because an error occurs when the CD file system (CDFS) driver interacts with a file-based write filter driver.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.
When you use the flat file boot method, Windows PE files are not stored in a boot image. Instead, Windows PE files are stored in a flat file directory structure. Windows PE is started directly from the flat file directory structure.
