I installed successfully Lubuntu 14.10 alongside Windows8. Being tired of seeing "Booting in insecure mode..." as the PC turned on, I enabled again "boot in secure mode" from Win. As a result the Grub didn't run anymore when I turned the PC on; so I disabled again "boot in secure mode" but Grub continues not to show up. 1) How can I fix the problem? 2) Besides, is there a way to hide "booting in insecure mode.." when starting the PC? Thank you!!
