Best Practices for Symantec Drive Encryption 10.3 and above on UEFI Systems such as Windows 8 or Windows 10
The following requirements apply only if you are encrypting your disk. If you are installing Symantec Encryption Desktop 10.3.2 MP13 or above for email or other Symantec Encryption Desktop functions, you can install on Windows 8/10 32-bit systems and boot using UEFI mode without having to meet these requirements. To encrypt systems booting in UEFI mode, the following additional requirements must be met:
System must be certified for Microsoft Windows 8/8.1 64-bit or Microsoft Windows 7 64-bit
UEFI firmware must allow other programs or UEFI applications to execute while booting
Boot drive must be partitioned in GPT with only one EFI system partition on the same physical disk
Boot drive must not be configured with RAID or Logical Volume Managers (LVM)
Tablets and any systems without a wired or OEM-supplied attachable keyboard are not supported For more information on the firmware and boot drive, contact your system administrator or hardware manufacturer.
Note: Symantec Drive Encryption is not compatible with other third-party software that could bypass the Symantec Drive Encryption protection on the Master Boot Record (MBR) and write to or modify the MBR. This includes such off-line defragmentation tools that bypass the Symantec Drive Encryption file system protection in the OS or system restore tools that replace the MBR.
