To fix Asus Rog Strix B450 F Disable Secure Boot read this guide. Many ASUS motherboards with UEFI BIOS come with Secure Boot mode enabled by default. It is simpler to install or set up Windows to dual boot on your computer if this capability is disabled.

On several models, it is impossible to turn off Secure Boot mode. Therefore, we must remove the BIOS keys that permit it. You can always go back and activate Secure Boot without difficulty, so don’t worry. You also don’t violate the warranty by turning Secure Boot on or off.

You must first activate GPT partitions on your computer with an ASUS motherboard before you can disable Secure Boot mode. For instance, if the machine is not in UEFI mode, you cannot install a copy of Windows on your computer. This mode must be supported or compatible with the hard disk partition style.

You can enable GPT partitioning on your hard disk when you enable UEFI mode. You can make as many partitions as you’d like, and they can be larger than 4 GB. Using a third-party program, or the command prompt are the two options for doing this.
