I drove to the site, picked up the machine, and last night found that the

If you want to boot a BIOS based machine with a GPT boot disk you need to have
a BIOS boot partition. Otherwise GRUB will have no place to write
the necessary bootloader code.
Yes, but that's a different issue. Unless I misread OP's thread, they
had a disk with an MBR label and created one partition which was set to
GPT type. This indicates to the OS that a GPT label should be found
within the area described by that partition. There wasn't one, which
caused the boot failure.
Users generally should not set an MBR partition type to GPT.
