How to Disable Secure Boot in BIOS and Windows

A detailed guide on disabling Secure Boot on ASUS, MSI, Gigabyte, Dell, HP, and Lenovo devices.

⚠️ Important: changing BIOS/UEFI settings may affect Windows startup. If you are not confident in your actions, create a restore point and back up important data before making any changes.

What Is Secure Boot

Secure Boot is a built-in UEFI security feature that verifies the digital signatures of the Windows bootloader, drivers, and system components during startup.

If the system detects an unsigned driver or an untrusted module, the boot process may be blocked.

Why Disable Secure Boot

Many programs that work at the Windows kernel level use their own drivers. In some cases, these drivers:

  • do not have a Microsoft signature;
  • are blocked by the UEFI security system;
  • cannot load while Secure Boot is enabled.

Because of this, an application may fail to start or work incorrectly. That is why users often search for:
