When flashing a desktop board with TXT (Trusted Execution Technology) enabled in the BIOS an update to the BIOS initiated within Windows will fail.
Prior to initiating the BIOS update reboot and disable TXT then run the update.
Once the update has completed and the system has finished its post update boot shut the system down. Pull the power and let it sit for a minute.
Power the system up and F2 or DEL into the BIOS. Verify that the update did not change any of the settings and enable TXT.
We enable TXT before installing the operating system by default. We also make sure the drive mode is set to AHCI.
