how to.enable secure boot

To enable Secure Boot, follow these general steps:

1. Check if Secure Boot is already enabled in Windows by typing "system information" in the search and looking for "Secure Boot State." If it says "Off," continue to enable it.
2. Open the Windows Settings and go to "Windows Update" > "Advanced options" > "Recovery." Under "Advanced startup," click "Restart now."
3. Upon restart, choose "Troubleshoot" > "Advanced options" > "UEFI Firmware Settings" to access your BIOS/UEFI setup.
4. In BIOS/UEFI, navigate to the Boot tab. Disable Compatibility Support Module (CSM) by setting "Launch CSM" to Disabled.
5. Find the Secure Boot option and enable it. Make sure the OS type is set to "Windows UEFI mode" and Secure Boot mode is "Standard." If needed, install the default Secure Boot keys.
6. Save and exit BIOS/UEFI (usually F10). Your computer will restart with Secure Boot enabled.
7. Verify in Windows "System Information" that Secure Boot State is now "On."

Note: BIOS interfaces and exact steps may vary by manufacturer. Some PCs require the disk partition style to be GPT and boot mode to be UEFI for Secure Boot support. Back up important data before making changes in BIOS. This process applies broadly to Windows PCs and many motherboard brands.
