I tried post 44 again: I downloaded the media creation tool, saved it to desktop, ran the tool selecting create installation media for another pc, selected options English, Windows 10, and 64-bit, checked 'use the recommended options for this PC', dotted 'USB flash drive', it identified the USB stick I wanted to use and installed it. Then I opened the flash drive (left click), right clicked setup and selected run as administrator. The result was the same as before: "Windows" icon appeared for 30 sec and then I got the same message that Setup couldn't properly start.... reboot and try again. I noted a message in the first part of this instruction about disabling secure boot?? Would that be an issue??
I did not try disabling secureboot , not yet anyway, I found myself guessing at too many settings and decided against it until I've learned a little more about it. So, I guess I'm hold for now.
Maybe this will be more helpful?
After installing Microsoft Update KB3133977 for Windows 7, some users may encounter a the system fail to boot into the operating system.
EDIT: I honestly don't think this will make a difference, but I could be wrong.
I'll try it next. The secureboot disable did not solve the problem.
I noticed that my UEFI version is a 2013 build; would you recommend an update to see if it has any effect?
Sure, try updating your firmware

Then restart in normal mode.
Sounds silly - but it is a legitimate fix for some issues - don't know why.
Is a flaky profile causing this on your machine?
Launch Command Prompt (Admin)
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList" /s > %TEMP%\profList.txt
Attach the profList.txt file in your temp folder to a new post - thanks.

Since I touched on profiles, try creating a new local admin account, sign-in to the new account and try WU.
