Windows 10 Defender Offline stuck in infinite restart loop

Yesterday 4/5/2017 I used one of my computers to upgrade from windows 10 version 1607 to version 1703. Then I tested for WDO blue screen boot loop with windows driver verifier.

The WDO blue screen boot loop will soon be history. The updated windows 10 version 1703 did not produce any WDO blue screen boot loops!!!!!!!!

 

You can always do a non-destructive repair.

 

Does your computer display Blue Screen of Death (BSoD) error message screen?

Do you have Windows 10 Installation DVD?

Have you changed or install anything before problem started?

When you turn on your computer, make sure that the fans are running in the very beginning.

The other reason your computer might be turning off is because the computer is over heating. The CPU is not getting a lot of air flow, when you turn on the computer, and when it goes into the operating system, the PC temperature goes up high, that's why computers need fans. But what is causing the PC to over heat? Well, its DUST!!!
Clean all dust and dirt from inside your computer and apply new thermal paste to CPU.

Please try a hard reset and see if it works.
1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER 'button down on your laptop for about 15 seconds.
4. Plug in the a/c power supply (without battery) and power on.


Reseat the memory to see if any difference. If no change-try with one stick of memory, then the other to determine which one is bad, or if both need replacing.


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.

Following command will fixes errors on the disk and locates bad sectors and recovers readable information.


Code: Chkdsk D: /r[/quote]

Please replace partition letter D: 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.

 

Have you executed Chkdsk command?
Also please list of thinks you have done to repair Windows 10 this will help us lot.

 

yes done the chkdsk, that was ok
most of the options when booting in recovery fail .
only one I haven't done is a full wipe n start again.
trying to get in to safe mode didn't work.
is there away to make a boot disc to get into safemode?

 

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.

The following command scans integrity of all protected Windows system files and repairs files with problems when possible.

Code: Sfc /Scannow /OFFBOOTDIR=D:\ /OFFWINDIR=D:\Windows[/quote]

Please replace partition letter D: 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.




After Sfc command finish executing test your computer to see it will boot into Windows OS if not follow below instructions.









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 that’s 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 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[/quote]
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.

 

cant get
Sfc /Scannow /OFFBOOTDIR=D:\ /OFFWINDIR=D:\Windows

to run, it just give me the rundown as to all the different codes to use, eg: OFFWINDIR

 

This is happens when you type the SFC command wrong is there a chance you can upload screenshot of the SFC command.

 

You have not leave space between /OFFBOOTDIR=C:\ and /OFFWINDIR=C:\Windows parameters.

 

thanks
tried that, it did find some errors.
but still will not get passed the boot loop.
maybe time to reformat start again ?

 

Try Hiren's BootCD. There are some good tools on that.
