Fix: Windows 10/11 Installation Failed Error 0x800f0830-0x20003

Recently, I attempted to upgrade my Windows 10 Home PC to Windows 11 Home. Despite investing a significant amount of time and effort, I encountered the error 0x800f0830 – 0x20003 during the installation/upgrade process on both of my laptops.

On the Windows 11 Setup screen, you will see below error message:

Error Message
“We couldn’t install Windows 11” We’ve set your PC back to the way it was right before you started installing Windows 11. 0x800F0830 – 0x2003 The Installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation.
0x800f0830-0x20003
0x800f0830-0x20003

To upgrade my Windows 10 PC to Windows 11, I initially downloaded the installation media/ISO from the Microsoft website https://www.microsoft.com/en-us/software-download/windows11 and proceeded to extract the ISO into a folder. Following this, I initiated the upgrade process by running the setup.exe file from the extracted Windows 11 ISO folder.

The installation process initiates successfully by checking for updates and then displays the “Installing Windows 11” page with a cancel button. However, upon reboot, the system attempts to check/install updates, consistently encountering failure when it reaches 10 to 11 percent.

The system restarts once more, and a message appears on the screen stating “Undoing changes made to your computer“. This process reverses the Windows 11 installation, restoring the system to its previous state.

After another restart, you will encounter a pop-up window with an error message:

Error Message
“We couldn’t install Windows 11” We’ve set your PC back to the way it was right before you started installing Windows 11. 0x800F0830 – 0x2003 The Installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation.

After resolving this error code, I successfully installed/upgraded Windows 11 on two of my systems: one from Windows 10 Home to Windows 11 Home and the second from Windows 10 Enterprise to Windows 11 Enterprise. The solution outlined in this blog post proved effective, saving a considerable amount of time and ensuring the successful completion of the Windows 11 installation.”

Fix 1 – Disconnect from the Internet

While attempting various solutions, including checking if the developer mode is disabled on the Windows 10 system before initiating the Windows 11 installation, resetting the Windows Update service, and rebooting the system, none of the fixes proved successful. Each time, I encountered the same error message (0x800F0830 – 0x2003).

As we know, this error message occurs during the Install_Updates phase when the setup is attempting to download and install updates to ensure the system has the latest drivers for all connected components. To address this, disconnect from the internet before starting the Windows 11 setup using the ISO and maintain this disconnected state throughout the entire installation process.

If possible, disable the Wi-Fi adapter and remove any LAN/Ethernet cable attached to the system. Additionally, disconnect any external devices such as USB hubs, external HDDs, or connected USB devices, including printers, before initiating the installation.

This should undoubtedly resolve the issue and fix this particular error. Another helpful tip is to choose “Not right now” on the “Get updates, drivers, and optional features” window that appears just after starting the setup process by double-clicking on the setup.exe, as illustrated in the screenshots below.

Fix 2 – Ensure Windows Version is Compatible

Make sure you are upgrading to the same level of Windows Editon. For Example: Windows 10 Home to Windows 11 Home Edition. If you are upgrading to Pro or Enterprise Edition then you may get this error message.

Fix 3 – Ensure there is enough free space in C:\ Drive

Make sure that there is enough free space available in your C:\ drive before you start with the upgrade process. The minimum free space required is 64 GB in C:\ drive.

Fix 4 – Run System File checker (SFC) tool

The error code 0x800f0830-0x20003 could be a result of corrupted or missing system files.

To identify and automatically replace corrupted system files in Windows, you can use the System File Checker (SFC) tool. Before running the “sfc.exe” tool, it’s advisable to first execute the DISM (Deployment Imaging Service and Management Tool) command with the “/Restorehealth” switch.

SFC tool will scan all protected system files and replace any corrupted files with a cached copy from the “%WinDir%\System32\dllcache” folder.

Check any component store corruption

DISM.exe /Online /Cleanup-image /checkhealth

Scan to check Corrupted files

DISM.exe /Online /Cleanup-image /scanhealth

Repair Corrupted files

DISM.exe /Online /Cleanup-image /Restorehealth

Scan Corrupted files and replace them with a Cached copy

sfc /scannow

  3. Bump up – enabled TPM & secure boot in BIOS, bypassed 6th generation Intel problem, install via ISO — but had the “How to fix Error 0x800f0830 – 0x20003” error. Found this page, didn’t disconnect any USB or anything, only disconnected network: worked!! Great thanks.
