Windows 10: W10 Upgrade from W7 sticks on logo - error 0xC1900101 - 0x20017, installation failed in the...

Hi, I am trying to help an elderly friend upgrade his old W7 desktop to W10.
Having checked the specs against requirements I thought it would bee straight forward. But now I don't know what else to try.
can you please help? I have read as many posts as possible, and followed the advice as much as I can.
But the pc always sticks at a W10 Logo, no circling dots....

Given what I have tried - see below - I am wondering if I boot straight into DOS and load from there which it suggests I can, although everything else I have tried has failed so I don't really know will I have a licensing issue.
My friend is elderly, and I am unsure as to his financial situation.

Any help and advice would be gratefully received. Thankyou in advance. oh, and I did create a System Image prior to all of this.. .:
So...

W7 Home, on a DELL Optiplex GX620;
6GB RAM,
400+Gb free disk space.

NB the Windows update program stated no updates installed since 2018
NB if run Updates manually it kept installing 5 updates others have had this issue , but they do not appear in the Update History.


Upgrading

If I try upgrade from that pc directly, using media creation tool upgrade this pc,
after sticking on logo for aaaages, and therefore I cancell by a reboot, it tells me
We couldn't install Windows 10
we've set your pc back. .. blah blah blah
Error 0xC1900101 - 0x20017 The installation failed in the SAFE-OS phase with an error during BOOT operation

I have tried with USB and ISO CD created via Media Creation tool to upgrade another pc.

Tried fixing Windows Updates - unsuccessful
stopped Windows Update Service and deleted folder c\software distribution.
Followed instruction to download and manually install KB updates, none of which were applicable to my pc.

Also have:-
removed all external devices bar the USB for upgrade and Ethernet for internet
uninstalled Norton
uninstalled MS security essentials
ran malwarebytes - nothing.
running a clean boot & stopped other start up programs
ran disk check - ok
ran windows memory check - ok
updated ALL drivers manually no wifi or Bluetooth, its an old desktop with windows "utility".

reset BIOS to default settings.

disk clean up

deleted software update folders ?BT ? & something else.


tried UPGRADE again
Accept T&Cs
choose what to keep - NOTHING...
asks to conform choice!

Installing Windows 10... but after a reboot it is now stuck on the W10 logo, no circling dots...


Help... please....

There is a log missing





Setuperr


Maybe it holds the clue.


Did you try the list of quick fixes which include removal of third party AV.

Anniversary update fails with error 0xC1900101 - 0x20017

I followed the directions C: > Windows > Panther and found the two text files, setuperr dated 9-15-2016 on a failed attempt





Setuperr below, appears ATI drivers are listed at the top. Maybe this is what the troubleshooting page refers to, I'm not uninstalling them. W10 should replace them with MS working drivers if the W10 AU can't handle them. It could be the problem, but it wasn't a problem the first RTM or the November update.

Since the AU is now considered the "paid" version for those that didn't take advantage of the free upgrade W10 may be picky about an install. I'm not doing a clean install, if W10 is now the new "running as a service OS" it should be able to update itself without issue. Meaning any computer running any version of W10 without problems should upgrade without problems.
