Why Enable Secure Boot?
Secure Boot verifies that only digitally signed software, validated by trusted authorities like Microsoft, runs during startup. This prevents malicious code from compromising your system. It’s recommended to keep Secure Boot enabled unless specific requirements, such as running non-supported operating systems, necessitate disabling it. Always be aware of the security risks when disabling Secure Boot.
Note: If your drive is encrypted with BitLocker or Device Encryption, you may need your BitLocker recovery key to access the system after modifying BIOS settings. Magic Recovery Key is helpful in this case.
