Technical Articles ID: KB83322
Last Modified: 2022-06-16 06:45:04 Etc/GMT

Environment

Drive Encryption (DE) 7.1.x

Dell Latitude 3340

NOTE: This solution also applies to other manufacturer and computer models.

For details of DE supported environments, see KB79422 - Supported platforms for Drive Encryption 7.x.

Problem

During system startup, the system becomes unresponsive while trying to load the preboot authentication screen.

The preboot authentication screen fails to load after you successfully install DE, add users, encrypt the disk, and restart the system.

Only a blank background screen is generally shown.

The user is unable to authenticate at preboot.

When the system is decrypted and deactivated, the system can successfully boot into Windows.

Solution

To resolve this compatibility issue, decrypt the computer and enable the option Enable Pre-Boot Smart Check before you redeploy DE.

Use the DETech recovery media to perform an Emergency Boot and gain access to Windows.
At the ePO console, navigate to the DE Product Settings policy and select the option to Decrypt the computer.
After the decryption completes on the endpoint, select the Enable Pre-Boot Smart Check option in the ePO policy, then redeploy the product.

For assistance with configuring policies, see the relevant product guide. For assistance with creating a DETech recovery media, see the relevant DETech User Guide.

For product documents, go to the Product Documentation portal.

Related Information

The following Pre-Boot Smart Check details have been included in several DE Known Issues articles to assist in overcoming problems with some systems.

Example taken from KB84502 - Drive Encryption 7.x Known Issues:

Issue: Hardware incompatibility incurred during deployment.

Resolution: Before deploying DE to your site, we recommend that customers qualify the product first on a subset of the hardware used throughout your environment. If during this test deployment hardware, compatibility issues are encountered, we recommend the usage of the feature Pre-Boot Smart Check, as this can overcome a number of common compatibility issues. By performing the 'PreBoot Smart Check' ahead of the rollout, a customer can scope which computers might require this feature to be enabled during production deployment.
