General Troubleshooting - First Steps.

NOTE: This procedure is designed to provide broad troubleshooting for upgrade rollback issues. You should use this procedure only if there is no issue-specific or error-specific guidance available.
  1. Check for data backup - If the system has had an issue with the upgrade, we should recommend extra caution if there is data on the system that is not also saved elsewhere.
  2. Check for known issues based on the error code. Try to resolve known issues with targeted actions before using the troubleshooting guidance below.
    • If the customer is getting one of the following location codes, ask them to try again. Many customers are able to install on the second or third attempt if they are seeing these: 0x2000C, 0x2000A, 0x3000D, 0x4000D. If they have tried repeatedly, and it is still not upgrading, continue with other troubleshooting steps.
    • You may need two parts of an error code – the error, and a location code. For example, the error "0xC1900208 – 0x4000C" - 0xC1900208 is the error code, and 0x4000C is the location code. If the customer is upgrading from Windows 7 SP1, or from an earlier build of Windows 10, the error code may show in Windows Update, but not show the location code. To find the location code, check the customer’s Setupact.log file, identify the time of the error, and look for the line for the failure with the location code that is the same time as the error.
  3. Ask if setup stalled and the system was restarted manually, or if the upgrade rollback happened without user action. If setup stalled/hung, troubleshoot based on when the hang occurred. Prep for Upgrade and then re-try.
  4. If it is a Surface, check the Surface site for steps to upgrade this specific model.
  5. Note the upgrade path/method used.
    • If the issue happens early in upgrade and they are using Windows Update to upgrade, consider using a downloaded ISO.
  6. If installing from ISO, DVD or USB: Check Installation Media
    1. Verify the source of the installation media. We support installation only when using a Microsoft-provided Windows 10 installation source. This means a download from a Microsoft site, or media provided by Microsoft.
    2. If the installation source was a download and the symptom is not a known issue:
      1. Check the ISO hash using FCIV.exe or another sha1 hash tool. For more info, see Microsoft KB889768 - How to compute the MD5 or SHA-1 cryptographic hash values for a file
      2. If the hash is mismatched with the published value, re-download.
      3. If the hash matches, mount the ISO and re-try setup, or re-create the media from the ISO if installing on a different system.

Upgrade via Windows Update fails before first restart

  1. If using Windows Update: Use Windows Update troubleshooting procedures.
  2. Re-try the upgrade.
  3. If the failure returns and it is not a known issue, perform the Prep for Upgrade steps listed below.
  4. Re-try the upgrade.

Upgrade fails after one or more restarts

  1. Perform Prep for Upgrade steps.
  2. Re-try the upgrade.

Prep for Upgrade Steps

NOTE: While performing these steps, watch for signs of malware infection. Upgrade is not recommended on an infected system.
  1. Update Windows so that all available recommended updates are installed.
  2. Uninstall third-party antivirus software for the upgrade.
    1. Use Windows Defender for protection during the upgrade.
    2. Recommend that the customer check for compatibility information and re-install their preferred solution after the upgrade.
  3. Uninstall any unneeded software.
  4. Remove non-essential external hardware.
  5. Check for and recommend installing updated firmware and drivers on the system manufacturer website.

Malware Infected system

If the system is found to be malware infected, we should recommend one of the following:

  1. Malware removal
  2. Clean install Windows 10

Error Code and possible root cause:

  • 20004
