win 10 upgrade crashes computer and will not load windows

PC Win7 64 bit. I tried to do Win 10 upgrade and not save files or apps. PC crashed during upgrade. I tried all the steps listed. It would not let me load image disks that I had made or the system repair disk. I tried to restore to factory setting.
That didn't work. Now the computer tries to load windows but its tells me the computer was shut down improperly and restarts with the same message. It will not start in save mode.

 

Win 10 will not load. Completely stuck


This is what I'm seeing

 

REGEDIT won't load hive from Win 10 to Win 8.1

The story in a nutshell:

• I use PuTTY a lot
  
• I back up my file system regularly
  
• I got tired of Win 10 freezing on me every couple of minutes, so I decided to reset my PC to factory settings (Win 8.1)
  
• I forgot to export my saved PuTTY sessions from the registry
  
• I found this post, which kindly suggests to load an old, backed-up NTUSER.DAT file into the HKEY_LOCAL_MACHINE within the Registry Editor
  
• The DAT file was last updated in the Win 10 installation I had before resetting to factory settings with Win 8.1
  
• I get the following message from the regedit:
  

I can only make an educated guess that it fails to load the hive from this file because the file was last written from Win 10.

I should note that an older NTUSER.DAT file, which roots from the older Win 8.1 installation (before the upgrade to Win 10), does go through hive loading successfully, but it doesn't contain what I need.

Am I doomed to pay for forgetting to export the settings from the Win 10 registry?

EDIT:

This doesn't seem to be a permission issue
