6.6 Secure Boot – What It Is & Should You Disable or Enable It?
Secure Boot is a built-in security feature found in modern PCs that protects your system during startup. It decides what is allowed to load when your computer turns on.
What Is Secure Boot? (Simple Explanation)
When you press the power button, your PC does not start Windows immediately. First, the system firmware (UEFI) checks whether the operating system is trusted and not modified.
- If everything is trusted → Windows loads normally
- If something is untrusted → boot is blocked
Secure Boot protects your PC from boot-time viruses and rootkits.
Why Secure Boot Exists
- Stops malware before Windows starts
- Prevents boot-level hacking
- Protects system files from tampering
- Required for Windows 11 installation
When You SHOULD Keep Secure Boot Enabled
- You are a normal home or office user
- You only use Windows (10 / 11)
- You want maximum security
- Your system works without issues
For 90% of users, Secure Boot should remain ENABLED.
When You MAY Need to Disable Secure Boot
- Installing Linux or dual-boot systems
- Using old operating systems
- Booting recovery or diagnostic tools
- Fixing certain boot or driver compatibility issues
Disabling Secure Boot reduces protection. Do it only when you clearly know why you need it.
How to Check Secure Boot Status in Windows
- Press Win + R
- Type
msinfo32and press Enter - Look for Secure Boot State
- Status will show On or Off
How to Enable or Disable Secure Boot (Step-by-Step)
- Restart your PC
- Press F2 / F10 / DEL / ESC (varies by brand)
- Enter BIOS / UEFI Settings
- Go to Boot or Security tab
- Find Secure Boot
- Set it to Enable or Disable
- Save changes and exit
Never change other BIOS settings unless instructed. Wrong changes can prevent Windows from booting.
