ASUS UEFI Secure Boot is a security feature that prevents unsigned or tampered software from being loaded during system startup. In this article, you will learn how to enable Secure Boot on an ASUS device, what advantages it offers, and what obstacles you should be aware of.
What is ASUS UEFI Secure Boot?
Secure Boot is part of the UEFI (Unified Extensible Firmware Interface) standard, the successor to the classic BIOS, and supplements it with advanced protection mechanisms.
- Enabling Secure Boot ensures that only software with a valid digital signature is loaded during startup. This makes it much more difficult for malware and boot kits to run.
- The process uses a stored whitelist of trusted signatures. Applications or drivers without a valid signature are blocked.
- Secure Boot provides an additional layer of protection, especially for users with sensitive or security-critical data.
How do I prepare my ASUS system for Secure Boot?
Before activation, you should check whether your device is UEFI-compatible and whether the firmware is up to date.
- Perform a full data backup to avoid losing information in case of problems.
- Check the compatibility of installed software and drivers with Secure Boot. Older applications often require updates or replacement versions.
- Install the latest drivers and system updates to avoid startup problems later on.
How do I enable Secure Boot on an ASUS device?
Start the computer and access the UEFI Setup (BIOS) by pressing the F2 or Del key during the boot process.
- Navigate to the Boot menu item and select Secure Boot. Enable the feature.
- Set the Secure Boot Mode option to Standard. This will only allow trusted signed software.
- Save your settings and restart to activate protection.
What challenges can arise with Secure Boot?
A common stumbling block is the incompatibility of older hardware or software that does not have valid signatures. This can cause startup errors.
- Some alternative operating systems (e.g., certain Linux distributions) are blocked by default because they are not stored as trusted.
- In such cases, it may be necessary to temporarily disable Secure Boot in order to perform installations or repairs.
