I've already uninstalled my Windows and installed Elementary Freya OS. But then my laptop won't reboot. It said "Reboot and select proper boot device ..."
Here is the complete specification of my laptop : complete specifications
Did this happen because I haven't turned off my EFI mode via the Windows 8 setting before I removed the Windows OS? If it was so, then how can I set it off directly from the BIOS?
** my laptop type is asus a450c
