Hi Colin, Welcome to Microsoft Community and thank you for your interest in Windows 10. • Select the Boot menu in the Aptio setup utility, select 'Launch CSM' and change to enable. • Select the Security menu n the Aptio setup utility, select 'secure Boot Control' and change to disable. • Select Save & Exit and press 'yes'. • Hold down the power button until the unit switches power off completely. • Switch back on and continually press the F9 button for about ten seconds; this should now allow the unit to boot up into the Windows Recovery menu.
