    Win10 Creator Fast Track in boot loop after AVG sotware removal


    All was running well on latest Fall Creator with exception of an occasional mis-direct on internet sites with what appeared to be a virus. Ran deep scan on defender to no avail. Down-loaded AVG with the same results. Since it was of no value, decided to remove AVG using uninstall. Required a restart and went into continuous loop. Power on, Preparing Automatic Repair with logo for 1.5 revolutions of circle and then power on again.

    Created a usb boot from media creator and nothing is working. Suggestions, etc.

    Tried Bad registry entry in regedit, bootrec, and most other solutions, no joy.

    Sys was orginal win 8 and upgraded early on when Win 10 came out in eval release and member of fast track with all the latest but I never created any type of recovery CD, My Bad.

    Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so thatís as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.


    Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

    Please type below command into Command Prompt and press Enter key.

    Code:
     Dir C:\Windows\System32\config\RegBack

    Above command will list files stored within RegBack folder and there file size, make sure files are not zero size if they are do not follow below instructions.



    Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

    Please type below commands into Command Prompt and for each command you have typed press Enter key.



    Code:
    Ren  C:\windows\system32\config\SAM         SAM.BAK
    
    Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK
    
    Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK
    
    Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK
    
    Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK
    
     
    
    Copy  C:\Windows\System32\config\RegBack\SAM         C:\windows\system32\config
    
    Copy  C:\Windows\System32\config\RegBack\SYSTEM      C:\windows\system32\config
    
    Copy  C:\Windows\System32\config\RegBack\SECURITY    C:\windows\system32\config
    
    Copy  C:\Windows\System32\config\RegBack\DEFAULT     C:\windows\system32\config
    
    Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config

    This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.


    Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

    So you did replace corrupted registry hives with registry hives store in RegBack folder?
    What was the error message display by bcdedit command?

    You have not answered above quoted question.

    Bootrec /FixMbr
    
    Bootrec  /FixBoot
    
    Bootrec  /RebuildBcd
    Please let me have the output of these commands if you can post a screenshot.

    Yes, I replaced the registry files and also one of the first attempts was the bootrec prior to this post

    I was finally able to install a new version of windows and am now in the process of getting stuff together and able to at least get to the old docs and other items by going to old. can't get to favorites, etc. but should be able to remember.

    I'm going to mark it as solved by totally reinstalling windows and starting over. Did not seem to be any other solution.
