[INFO] BF2042 Patch 8.8 (May 27) – Secure Boot Requirement for Supported Systems

How to Enable Secure Boot on Acer Nitro 5 AN515-58:
Detailed Guide

Secure Boot is an important security feature that helps prevent unauthorized operating systems and
malware from loading during the startup process. Enabling it on your Acer Nitro 5 AN515-58 requires
careful steps in the BIOS settings. Here's a comprehensive guide:

Prerequisites

• Ensure your laptop is plugged into power (not running on battery)
• Have a USB flash drive ready to backup important data (recommended)
         Note that some older operating systems may not support Secure Boot

Step-by-Step Instructions

Access BIOS Setup(source)

1. Completely shut down your laptop by holding the power button for 10 seconds
2. Power on the system and immediately press the F2 key repeatedly until the BIOS menu appears

Set Supervisor Password (Required)(source)

• In BIOS, use the right arrow key to select the Security tab 
• Highlight Set Supervisor Password and press Enter 
• Create a password (8-20 characters, alphanumeric) and confirm it 

  Important: Write this password down and store it securely
  Warning: Losing this password could potentially brick your device if a BIOS update fails 

Enable Secure Boot(source)

1. Navigate to the Boot tab using the right arrow key  
2. Select Secure Boot and press Enter 
3. Change the setting from Disabled to Enabled 
4. If available, set Secure Boot Mode to Standard (not Custom)

Save Changes and Exit(source)

1. Press F10 to save changes
2. Select Yes to confirm and exit BIOS 
3. Your system will reboot with Secure Boot enabled

(Optional) Remove Supervisor Password

If you don't want to keep the supervisor password:

1. Re-enter BIOS (F2 at startup)
2. Go to Security > Set Supervisor Password
3. Enter current password then leave new password fields blank
4. Confirm removal (source)

Troubleshooting

if Secure Boot doesn't stay enabled:

1. Reset BIOS to defaults by pressing F9 while in BIOS (source)
2. Save changes and reboot to Windows to check Secure Boot status
3. Repeat the enabling process if needed

Additional Notes

• Some Acer Nitro models have reported "flaky" Secure Boot behaviour that may require a BIOS update to
  fix (source)
• If you plan to dual-boot with Linux, research Secure Boot compatibility with your distribution
  For AN515-58 specifically, ensure you're running the latest BIOS version for best compatibility
  Verification

To confirm Secure Boot is active:

1. Open Command Prompt as Administrator
2. Type:

   bcdedit /enum {current}

3. Look for "device" and "path" entries - they should reference "efi" paths if Secure Boot is working
   
   

Remember that enabling Secure Boot may affect your ability to boot from some external media or install
certain operating systems. If you encounter issues, you can always temporarily disable Secure Boot in BIO
when needed.
