HI Larry,
try booting into recovery mode and running "dpkg" (cable network connection required!) per the update guide and let us know how you get on!:
While in recovery mode, drop to "root" and run the following command to re-install grub! (assuming you have grub-pc on your Kali install?).
sudo apt-get update && sudo apt-get remove grub-pc && sudo apt-get install grub-pc
Restart with Ctrl + Alt Del, DO NOT CLICK ON RESUME!.
