http://www.tomshardware.com/answers/id-2225322/asus-uefi-boot-utility-secure-boot.html How to shut down Secure Boot on ASUS UEFI MB. Credit to romirez for the last clue I needed: set Master password on Main Tab BIOS. So here are the steps to disable Secure boot in ASUS BIOS; first make sure you have a clean formatted USB I just used an old 2gb and formatted to Fat32 label it PK Keys, put it in a USB port and boot up into BIOS. Go to Boot tab page down to "Secure boot" select by hitting "Enter" Should open "Secure Boot menu" should show Secure Boot state as "enabled" and Platform Key (PK) state as "loaded" Page down to "OS Type" select "Windows UEFI" Page Down to "Key Management" select by hitting "Enter" select 2nd entry "Save Secure Boot Keys" to USB. AFTER you have saved keys and confirmed on another computer that you have ALL 4 files: db, dbx, KEK, PK should be ~ 15 - 20 kb total. Page down to PK Management select "Delete PK" look right to info panel and read it, hit "Enter". This disables Secure Boot in ASUS BIOS. Hit F10 and reboot into BIOS Go to Boot tab page down to "Secure boot" select by hitting "Enter" Should open "Secure Boot menu" should show Secure Boot state as "disabled" and Platform Key (PK) state as "unloaded"
