My Lenovo G50-80 was running a Ubuntu 17.10 with no dualboot. The BIOS didn't allow me to change ANY of the options and USB/DVD boot did not work for a few weeks or maybe months (I don't check BIOS every day).

Also it seems that grub failed when doing an apt upgrade (gave me a syscall error I/O) and the laptop turned itself into a brick because the "ubuntu"EFI entry also stopped working.

Right now I've set up a PXE server and I'm trying to install Windows 10 over LAN. If I can get it to boot, I'll try to apply the latest BIOS patch (only available for install through Windows) and see if everything goes back to normal.
