Hi Josh Amato,

From what you’ve described, the boot files may have been corrupted during the update, which explains why startup repair, uninstalling updates, and system restore aren’t working.

Before reinstalling Windows, there are a few advanced steps worth trying. Boot from Windows installation media (USB or DVD), open the Command Prompt, and run bootrec /fixmbr, bootrec /fixboot, and bootrec /rebuildbcd to repair the boot configuration. If that doesn’t resolve the loop, you can also run sfc /scannow and DISM /RestoreHealth from the recovery environment to repair system files. In some cases, temporarily disabling automatic driver updates or rolling back specific drivers can help if a hardware driver conflict is involved. For environments with many devices, pausing updates until Microsoft publishes a Known Issue Rollback (KIR) may help prevent further disruption.

You can try the above steps and let me know the outcome. If this answer helps clarify the situation, I’d appreciate it if you could click “Accept Answer” so others with the same issue can find the solution.

If you're experiencing a boot repair loop after Windows updates and cannot access Safe Mode or perform a system restore, you can try the following troubleshooting steps:

1. Repair Boot Codes: Use the command prompt in the Windows Recovery Environment (WinRE) to repair boot codes. Run the following commands:

      BOOTREC /FIXMBR
      BOOTREC /FIXBOOT
   

2. Fix BCD Errors: If you encounter BCD-related errors, execute these commands:

      Bootrec /ScanOS
      bcdedit /export c:\bcdbackup
      attrib c:\boot\bcd -r -s -h
      ren c:\boot\bcd bcd.old
      bootrec /rebuildbcd
   

3. Check for Pending Updates: If you suspect that updates are causing the issue, you can check for pending updates and uninstall them using DISM commands:

      DISM /image:C:\ /get-packages
      DISM /image:C:\ /remove-package /packagename:name_of_the_package
      DISM /Image:C:\ /Cleanup-Image /RevertPendingActions
   

4. Use Command Prompt to Access Recovery Options: If you can access the command prompt, you can try to start a text editor like Notepad to see if you can access files or perform further troubleshooting.
5. Consider Repairing the System Hive: If the above methods do not resolve the issue, consider restoring the system hive if you have access to it in the registry.

If none of these steps work, reinstalling Windows may be the last resort, but these methods can often resolve boot issues without needing to do a full reinstall.
