Battlefield 6 says Secure Boot is not enabled
The anticheat needs Secure Boot turned on
Battlefield 6 won't start and asks you to turn on Secure Boot. EA says its Javelin anticheat needs Secure Boot, which in turn needs TPM 2.0, a GPT system disk and UEFI mode.
How to fix it
Press Windows key + R, type msinfo32 and open System Summary.
Check that BIOS Mode says UEFI and Secure Boot State says On.
If it is off, type tpm.msc in Run and confirm the TPM is ready to use.
Restart into Advanced startup, open UEFI Firmware Settings and set Secure Boot to Enabled on the Boot tab.
Save the changes, restart and launch the game again.
Check your PC or motherboard maker's guide first if you aren't used to BIOS settings.
