Symptoms

A Latitude or Precision laptop may enter a boot loop after updating the BIOS. The BIOS update causes an issue if Intel Total Memory Encryption (TME), Intel Trusted eXecution Technology (TXT), and SystemGuard SecureLaunch are enabled. Intel TME and Intel TXT are updated in the BIOS, while SystemGuard SecureLaunch is enabled in the operating system.

The Dell logo and operating system loading circle are seen, then the computer reboots. This repeats infinitely.

Windows Autorecovery loads after a boot loop, but it is either unable to resolve the issue or it resolves it but then SystemGuard SecureLaunch is disabled.
