Bah, just as I was finished enabling syslinux using syslinux-install_update
and rebooted, the system did not respond, just a blank screen and lighting
shutting off, then rebooting again. 

Thus, this system needs an overhaul -- apparently some difficulty with the
bootcode or the MBR, though I am able to mount the old partitions and chroot
into them using arch-chroot. 

I tried installing grub using the standard method grub-install according to
the wiki, with little success -- some good news at least relevant to previous
topic in this thread is that grub recognized and added the intel-ucode file I
had copied to the /boot directory, when running grub-mkconfig.

The plan forward is to forget about generating new mbr using gpart and
install Debian at the end of the disk to, hopefully, restore some boot
related stuff that might have come crashing down after meddling with

I was able to jot down this at my remote terminal.
