It happened again right now, on another G40-30 Lenovo laptop, running Windows 10 and Ubuntu 16.04, both in legacy mode. As soon as we inserted an Ubuntu 17.10 live USB, the boot setup had the USB listed twice. One in legacy and another as EFI (I repeat, the OSs on that laptop are installed in legacy mode). By selecting to boot the live USB which was listed as EFI, it booted fine. We did not install the new OS, but after shutting down the laptop, the BIOS refused to save any changes and also refused to read that same USB flash drive in boot options. There has to be something very seriously wrong here.
