Good news! FINALLY have a clean grub menu with working Ubuntu option and a SINGLE and *WORKING* Windows 8 option.
I still get those error messages at power up, but currently it all works as I needed, so I'm not in a hurry to fix those right now.
All I can say is: what a mess!
Followed by: THANKS OLDFRED! I know this was probably just as frustrating for you as it was me. I also had to turn the execute bit off on the /etc/grub.d/30_uefi-firmware file (don't know if that is a "standard" file, generated by boot-repair, or what). That file created all of the screwy UEFI entries in the grub menu.
Thanks again! If you have any idea on the error messages at boot as mentioned previously I'll sure be all ears!
