how to enable secure boot after the installation

  • 772
  • Kubuntu 14.04 64bit on a MS-DOS (MBR) type HDD (sda4)
  • Kubuntu 14.10 64bit on a GPT type HDD (sdb5)
  • Windows 8.1 64bit on a GPT type HDD (sda3)

these are my installed OSes, both kubuntu installations were made with "secure boot off" state. Now I need to turn secure boot ON. but enabling secure mode ignores the grub and head to windows 8. also it indicates an error with the boot saying "invalid signature detected..."

do I need to add grub-efi signature to efi-firmware? or how can I enable secure boot correctly?
