I reinstalled Ubuntu 16.10 (for MBR partition format compatible with BIOS and UEFI), and reinstalled your GRUB2. In particular, I ran ./configure, make, make install, and ./install-grub (but no update-grub) and there was no error. But if I reboots it, for some reason PCR 10~14 still contain only zeroes...
