Revos have an EFI bios, right? I used to get this all the time on my
Samsung Chronos, until I blew away the dual-boot and put it back into
legacy (aka "working") BIOS mode.

Boot-Repair <https://help.ubuntu.com/community/Boot-Repair> on a
bootable USB stick will likely fix it. Under certain circumstances,
Windows updates will routinely destroy grub, so keep this stick handy.
