Hello. I've been trying go get out of the aptio setup utility.. But to no avail. I've disabled the secure boot, enabled the CSM, switched off my laptop and then 'Reboot and select proper reboot device' appears. I hold down the F2 button, switched off my laptop (while still holding down the F2) and switched it on again. Aptio setup utility reappears again.... How do I really get out of this aptio setup utility? It's irritating. And, my laptop model is Asus UX303L. Please help me.
