This article details a conflict between PGP Whole Disk Encryption and Altiris.



After you encrypt your disk using PGP Whole Disk Encryption, your system will not boot to Windows. You succuessfully authenticate your passphrase at the PGP BootGuard screen, but you receive an error message Invalid LBAI and system fails to load the Windows operating system.

This issue occurs on systems encrypted by PGP Whole Disk Encryption and with the Altiris Agent installed. The Altiris Agent has the option to create an embedded hidden partition for BootWorks. BootWorks allows Altiris to communicate with an Altiris server and execute tasks before the operating system loads. This hidden partition causes an incompatibility issue with PGP Whole Disk Encryption and causes the operating system not to load.

Note: This article applies to PGP Desktop 9.6 and above running on Windows 2000, XP, and Windows Vista.


To resolve this issue, when you create the image for deployment, exclude the BootWorks Automation Partition in the Altiris' Image Explorer.
