ZENworks Full Disk Encryption provides an Emergency Recovery application that is a plug-in to Microsoft Windows Preinstallation Environment (Windows PE).
Windows PE enables you to build a boot CD, referred to as an emergency recovery disk (ERD), based on Windows components. The Emergency Recovery application plugs in to the Windows PE. After the device is booted with the ERD, you can use the Emergency Recovery application to attempt to repair or restore the master boot record (MBR) or GUID partition tables (GPT), decrypt encrypted disks, deactivate the ZENworks PBA, and perform other recovery operations.
