When updating the BIOS on a Latitude 5420 laptop with McAfee Drive Encryption, it is recommended to decrypt the drive first before proceeding with the update. This is because the BIOS update process may require a system reboot, which could cause issues if the drive is encrypted and the necessary decryption keys are not available. Similar to Bitlocker, McAfee Drive Encryption can cause compatibility issues when updating the BIOS. If the drive is left encrypted during the update process, it may result in an error or even a failed update. Therefore, it's recommended to decrypt the drive before updating the BIOS to avoid any potential issues. To decrypt the drive before updating the BIOS, you can follow these steps: Open the McAfee Drive Encryption software on your laptop. Select the "Decrypt" option and follow the prompts to decrypt the drive. Once the drive is decrypted, you can proceed with updating the BIOS. After the BIOS update is complete, you can re-encrypt the drive using McAfee Drive Encryption. Just be sure to follow the proper steps and ensure that the necessary encryption keys are available before encrypting the drive again.
