With UEFI BIOS, Secure Boot is frequently turned on by default on ASUS motherboards. On my new PC, I intended to create a dual-boot arrangement, however, doing so is not feasible with secure boot enabled. That required me to locate the motherboard’s Asus BIOS key, launch the Asus BIOS software, and turn off the secure boot on my Windows 10 computer.
The steps I took to disable secure boot using the Asus UEFI BIOS Utility on an Asus X99-Deluxe motherboard are reflected in this guide.

how Disable ASUS Motherboard’s UEFI secure boot
The majority of recent ASUS motherboards lack a setting that would enable customers to disable UEFI secure boot. The “Secure Boot Enabled” option is invariably greyed out and cannot be changed. The secure boot may be turned off, though, simply deleting the secure boot keys.
This is reversible so no need to worry about breaking the warranty or damaging the BIOS. BIOS’s Secure Boot menu should show Secure Boot state as “enabled” and Platform Key (PK) state as “loaded”
To disable the UEFI secure boot on ASUS:
- Make sure the “OS Type” is “Windows UEFI”
- Enter “Key Management”
- Select “Clear Secure Boot keys” (You will have the option “Install default Secure Boot keys” to restore the default keys after you cleared the Secure Boot Keys)
After you cleared the Secure Boot Keys, Secure Boot will be automatically disabled. You can set the OS Type to Other OS now.
