So...
THEORETCALLY if I wait until, say, next weekend and then download (create) a new Win 10 Pro bootable USB flash drive, and use that to boot the machine, it may boot correctly, and then maybe I could roll back the Sept. update on the C: drive?
I’ll try safe mode in the Win 10 Pro machine again, too, once I get this WIN 11 Pro machine all dialed in. The Dell Repair Software was telling me there was no restore point to go back to, which seems impossible, as I’d created one manually about 2 months prior, and there should have been even earlier ones, too. I know they get overwritten as the space allocated gets used up, but there used to be several listed. WTH. (eye roll)
I am all for getting a newer computer that will run Windows 11. I am actually a computer equipment hoarder. My wife and I each have a laptop that runs Windows 11 and I have 2 mini-PCs that run Windows 11 as well. The mini-PCs both cost less than $150 and are surprisingly capable even though each is used mostly for server duty.
Prime Days are coming up on the 7th. I am sure there will be some tempting deals on Windows 11 machines. I will likely be purchasing a Windows 11 “gaming” mini-PC with an Optilink interface to use as an “AI Server”. This has many interesting advantages, but takes a fairly powerful processor to work well.
Depending on how your Windows 10 computer was setup, it should have gone into recovery mode where you could have used Windows Restore to get rid of the latest update. You might be able to get it into Recovery Mode by repeatedly pressing your delete key or F2 or some other method depending on the computer. It seems to me that you already know how to get into your UEFI settings menu... it should be one of the options depending on how you get into that.
Here is the method to do this recommended by ChatGPT which is likely clearer than I could type out.

I am sorry. I sent out a response without noticing this.
System recovery is reliably unreliable. Here is a more lengthy and thorough technique from Grok:
