The error you're encountering indicates that Secure Boot needs to be enabled on your system. Here's how you can enable Secure Boot:
1. Restart your PC to access the BIOS/UEFI settings. You may need to press a specific key during startup (commonly F2, F10, F12, Del, or Esc) depending on your motherboard manufacturer.
2. Enter the BIOS/UEFI setup. 3. Locate the Secure Boot option. This is usually found under Security, Boot, or Authentication tabs. 4. Enable Secure Boot. Ensure that it's set to "Enabled". 5. Save and exit the BIOS/UEFI settings. Your PC will restart. Important: Before enabling Secure Boot, confirm whether your system uses Legacy BIOS or UEFI mode. Enabling Secure Boot on a system configured with Legacy BIOS (MBR) can make Windows unbootable.
