You can disregard the questions in my previous post. IT’S WORKING!!!

I downgraded refind to version 0.11.0. That was the solution for the HP Elitedesk 705 g4 model.

THANK YOU to anyone on this thread who tried to help me. Particularly @george1421. I really appreciate it!

Success!

For the Dell Optiplex 9020 here are the settings that worked:

Exit to Hard Drive Type: GRUB
Exit to Hard Drive Type(EFI): REFIND_EFI

Thank you Sebastian and George for your insights. They were very helpful in pinpointing where the issue was.

I"m going to guess these aren’t brand spanking new systems, but instead are refurbs.

Same specs eh? What about firmware/BIOS and their configuration?

Considering their age I wouldn’t rule out HW failure. Memory check?

I haven’t had it happen in awhile but I would zero the drives for good measure.
