To fix the securebootai.dll error without downloading any third-party files, you need to repair your system's existing files or address the specific software causing the conflict. DLL errors are usually caused by registry issues, malware, or corrupted system files.

Here is how to fix it safely using built-in Windows tools:

1. Run SFC and DISM Tools

Windows has built-in features to scan and replace missing or corrupted system DLL files automatically.

Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.
Type sfc /scannow and press Enter. Wait for the scan to finish.
Next, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Restart your computer.

2. Perform a Clean Boot

If the error occurs because of a conflict with a specific startup program (often associated with anti-cheat software or security tools), a clean boot will help identify it.

Press Win + R, type msconfig, and press Enter.
Go to the Services tab.
Check the box that says Hide all Microsoft services.
Click Disable all.
Go to the Startup tab and click Open Task Manager.
Disable all startup items, close Task Manager, and click OK in the System Configuration window.
Restart your PC. If the error is gone, enable services one by one to find the culprit.

3. Reinstall the Associated Program

If this error happens when you launch a specific application or game (such as Valorant, Vanguard, or specific AI-driven security tools):

Open Settings (Win + I) and go to Apps > Installed apps.
Locate the program that triggers the error.
Click the three dots next to it and select Uninstall.
Reinstall the program using its official installer, which will cleanly reinstall the required DLL file.

4. Check Secure Boot Settings

Because this DLL is tied to secure boot functions, ensure your system firmware is configured correctly.

Restart your PC and press the bios key (usually F2, F12, or Del) to enter the BIOS/UEFI menu.
Navigate to the Boot or Security tab.
Ensure Secure Boot is enabled.
Save changes and exit.

5. Use Windows System Restore

If the error started happening recently, you can roll your system back to a time when it worked perfectly.

Type Create a restore point in the Windows search bar and click it.
Click the System Restore button.
Choose a date before the error started appearing.
Follow the on-screen prompts and let Windows restore your files.

To narrow down the exact cause, let me know:

When does this error pop up? (At startup, or when launching a specific game/app?)
What Windows version are you currently running?

I can give you more specific steps once I know the exact trigger program.
