Let's see if this method can improve the boot failure.
Sometimes fixing the registry can improve or fix boot problems.
For this method (registry backup) to work the file sizes must be substantial.
If the file sizes display 0 then the backup will fail and you can abort the commands.
All of these commands are via the windows 10 iso windows advanced troubleshooting menu > command prompt > administrator: X:\windows\system32\cmd.exe > X:\Sources>
Please use a camera or smart phone camera to take pictures and post images of the results into the thread.
1) type or copy and paste: cd \windows\system32\config
It should display: C:\windows\system32\config>
2) type: dir
It should display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk, journal, regback, systemprofile txr, etc.
All of the file sizes should be sizeable. If it displays zeros then abort.
Make a new directory and name it backup5122018 or something similar.
3) type: MD backup5122018
Copy all of the files into this new directory.
4) type or copy and paste: copy *.* backup5122018
It should now display: bbi, bcd-template, components, default, drivers, elam, sam, security, software, system, vsmidk indicating the files were copied.
Change the directory to regback
5) type: cd regback
It should now display: c:\windows\system32\config\regback>
6)type: dir
It should display: default, sam, security, software, system etc
All of these files must be sizeable. If it displays zeros then abort.
7) type or copy and paste: copy *.* ..
It should now display:
DEFAULT
Overwrite ..\default? (yes/no/all):
8) type: a
It should now display: sam, security, software, system and that the files were copied.
9) type: exit
10) click turn off your PC
Remove the USB flash drive if you had changed your boot order. Otherwise you can leave it and power on your computer.
