To enable or disable Secure Boot in ASUS BIOS, the general steps are:
- Enter BIOS settings by pressing the [F2] key while powering on the device for notebooks or the [Delete] key for ASUS motherboards.
- Navigate to the Advanced Mode in BIOS by pressing [F7].
- Go to the "Security" or "Boot" tab depending on the BIOS version.
- Select "Secure Boot" option.
- To enable Secure Boot, set "Secure Boot Control" to "Enabled" or set "OS Type" to "Windows UEFI mode".
- To disable Secure Boot, set "Secure Boot Control" to "Disabled" or set "OS Type" to "Other OS".
- Save changes and exit BIOS by pressing [F10].
Additional notes:
- Secure Boot state changes may require loading default Secure Boot keys.
- Disabling Compatibility Support Module (CSM) might be necessary to enable Secure Boot.
- If Secure Boot causes boot issues, reverse the changes or convert the disk partition from MBR to GPT.
These steps apply to ASUS notebooks, desktops, and motherboards and the exact screens may vary by model and BIOS version.
