Need help in recovering windows 2016 server after filesystem corruption

[karlos78]

Trying to recover OS after filesystem corruption.
sfc /scannow found bunch of damaged files and unable to repair it
dism /online /cleanupimage /scan-health cannot finish with error 2, seems to me it is due to major corruption of components hive
wonder, is it possible to repair it

link to components hive : COMPONENTS.zip

Hi and welcome to Sysnative,

The COMPONENTS hive is badly damaged, and a number of system files (packages) seems to be missing.

Do you have backups of this system before the filesystem corruption? If you don't have backups I would suggest to perform an in-place-upgrade with the Server 2016 ISO.

In-place upgrade Server 2016

• Mount the Windows Server ISO and run Setup.exe.
• Use the option Download and install updates, drivers (recommended) and click Next.
• In the next screen select the image you want to install.
  
  
• Depending on your Windows Server version and license, you may see a screen prompting you to enter the licensing key.
• Then accept the EULA. To perform a in-place upgrade, you need to check keep personal files and apps. Then click Next.
  
  
• After clicking Next, an upgrade process will start checking for updates, when this is ready click install to start the in-place upgrade.

Unfortunately I don't have backups. I've tried to do in-place-upgrade, it completed, but updates are failing to install.

Hi,

Okay, but I presume that the log files in the first post are made before you tried the in-place-upgrade. Since you have no backups I would suggest to perform the in-place-upgrade again, so we can look at the remaining issues with Windows Update.
