You need to set Platform in "User Mode", Secure Boot in "Standard Mode" and Load Setup Defaults.

You could do it by Restoring Factory Keys:

  1. BIOS - Security - Secure Boot - Restore Factory Keys - Enter
  2. BIOS - Restart - OS Optimized Defaults - Enabled
  3. BIOS - Restart - Load Setup Defaults - Enter
  4. Go to BIOS - Main and check if UEFI Secure Boot is ON.

my tpm 2.0 and secure boot is enabled and i still cant launch my game
i had the same problem, i fixed. it was the secure boot which wasn't actually enabled. when i restore my default settings of key managment (secure boot), the system restore just the pk key and leave 0 value on the other 3 keys.. so windows doesn't recognize secure boot. I just figure it out by chance... i hope it can be useful to you. To see if secure boot and tpm are actually enabled on windows do as follow: open a power shell as administrator type: "get-tpm" to see if tpm is enabled type: "Confirm-SecureBootUEFI" to see if secure boot is enabled if both of them are actually enabled the game should work properly. Remeber, to enable secure boot you need to: disbale csm disbale fast boot enable secure boot as Windows UEFI restore default key managment values More on reddit.com

October 30, 2025 - have you turned off csm(compatibility support module) in bios? it can be a bit confusing to find but you may benefit from learning the model # of your motherboard (also found in bios) even if just searching online. sometimes theres a tutorial for specific motherboards because theyre more finicky then others you can always google each setting and the term used youre not familiar with, as i did to fix this issue. my problem was that the settings were under names which completely different from what i was told to look for by any and all sources. in short form, turning compatibility support module off will unhide some settings, even if your pc is UEFI enabled by standard like mine was

Answer (1 of 5): BIOS? Or do you mean UEFI? BIOS is very old, and it does not have the concept of “Secure Boot”. UEFI does. (UEFI is basically newer version of BIOS)
