Unable to Enable Secure Boot on Predator PH315-54 despite UEFI Mode

random445

I need help with Secure Boot on my Acer Predator PH315-54 (3060 GPU) laptop. I’ve tried everything I could find, but it still shows Secure Boot Off in Windows(On in bios), and I’m unable to switch it to On.

My system details:

BIOS version: 1.15 (latest from Acer support website)

Windows 11 installed

GPT partitioning

TPM enabled and active

In BIOS, UEFI boot mode is enabled.

Secure Boot State in msinfo32 show "Off"

I set the Supervisor Password in BIOS, after which all other Secure Boot settings became available except for “Secure Boot Mode,” which remains greyed out which is why i am not able to switch to custom mode then back to standard (a potential fix for the issue).

The Select an UEFI file as trusted for executing option is available, and I enrolled bootmgfw.efi,but it didn’t activate Secure Boot.

I tried restoring factory keys and erasing all secure boot settings, but nothing worked.

Even after reinstalling Windows Secure Boot remains off.

Hi random445,

Some users have found these steps can help when Secure Boot shows as “On” in BIOS but “Off” in Windows:

• In BIOS, disable Secure Boot, save and exit, then reboot back into BIOS and enable Secure Boot again.
• Instead of entering BIOS via the usual hotkey, try entering it from within Windows (Settings → Recovery → Advanced startup → Restart now → UEFI Firmware Settings) or by setting Safe Boot in msconfig.exe and restarting. In some cases, this triggers Secure Boot to register correctly.
