Windows 11 update failure

[COYS]

I've attempted several updates all end the same way: Windows 11, version 23H2 (repair version) install error - 0x800700c1. I have tried SFC scan, DISM health restore. i have created an ISO for windows 11 also USB and attempted to reset windows but then i just get a prompt saying Windows 11 failed to install, renamed the software distribution folder and lastly extended the size if the health recovery partition to 1.25Gb none have worked as yet so any help would be much appreciated.

Hi and welcome to Sysnative,

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Here is the SFCFix file, and the restore operation was completed successfully. Shall i attempt an update now?


Thanks Karl.

 

[Maxstar]

Yes, please attempt to update and post the result. If it fails attach a new copy of the CBS logs.

Download the

Farbar Recovery Scan Tool and save it to your Desktop:

Download the 64 bit version: - Farbar Recovery Scan Tool Link

• Note: Your antivirus program may report FRST incorrectly as an infection. If so, disable the real-time protection when downloading and running FRST.
• Right-click to run the tool as administrator. When the tool opens click Yes to disclaimer.
• Note: Ensure that the Addition.txt check box is checked at the bottom of the form within the Optional Scan area.
• Press the Scan button.
• Please wait for the tool to finish. It will produce two logfiles called FRST.txt and Addition.txt in the same directory the tool is run from (which should be the desktop)
• Post the logfiles FRST.txt and Addition.txt as attachment in your next reply.

here we go, both done

Step 1. Start the

Farbar Recovery Scan Tool again.

Warning: This script was written specifically for this system. Do not run this script on another system.

• Download the attachment fixlist.txt and save it to your desktop.
• Right-click on FRST.exe and select "Run as administrator".
• Press the Fix button.
• If for some reason the tool needs a restart, please make sure you let the system restart normally.
• When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
• Post the logfile Fixlog.txt as attachment in your next reply.

Step 2. Download

ESET Online Scanner and save it to your desktop.

• Right-click on esetonlinescanner_enu.exe and select Run as Administrator.
• When the tool opens select the English language and click on Get Started.
• Accept the license agreement, and select in the "Before we start..." screen the following options:
  • No thanks, I am not interested. (if you don't want to share anonymous data with ESET.)
  • Enable feedback system (recommended).
• Click on Continue and click on the Full Scan option.
• Select Enable ESET to detect and quarantine potentially unwanted applications - then click Start scan. (This may take some time.)
• When the scan is ready and if threats have been detected, select Save scan log. Save it to your desktop as Eset.txt. Click on Continue.
• ESET Online Scanner will now ask if you'd like to turn on the Periodic Scan feature. Disable this option if you don't want to plan the periodic scan.
• Click on Continue If you left feedback, click Submit and continue. If not, Close without feedback.
• Attach the scan log Eset.txt to your next reply.

The Secure Boot update failed to update a Secure Boot variable with error (-2147020471 = Secure Boot is not enabled on this machine.).

Please check the BIOS/UEFI-settings to be sure Secure Boot is enabled.

Run also the following command in an elevated PowerShell prompt and take a screenshot of the result.
