4 Methods to Fix “Windows 11 Install Has Failed”

Part 1: Why Get Windows 11 Installation Has Failed Error

Several factors can trigger the “Windows 11 installation failed” error, stopping the upgrade in its tracks.

• Insufficient System Requirements: Beyond hardware, Windows 11 demands specific system conditions. If upgrading from Windows 10, it must be a supported version and activated.
• Corrupted Installation Files: Windows 11 requires totally intact and complete installation files to function properly.
• Software Conflicts: The pre-existing software which includes antivirus tools together with third-party drivers and background applications generates software conflicts.
• Disk Partition Issues: UEFI systems running Windows 11 need a partition style based on GPT (GUID Partition Table) rather than MBR (Master Boot Record) which was used previously.
• BIOS/UEFI Settings: Proper firmware configuration is critical. Secure Boot must be enabled, and the boot mode should be UEFI for GPT disks.

Part 2: How to Fix Windows 11 Install Has Failed

Tackling the “Windows 11 install has failed” error starts with understanding its origins, but knowing how to fix it is what gets you back on track.

The following methods offer straightforward ways to address compatibility issues, remove specific error codes, adjust your disk setup, and eliminate software interference. With tools like 4DDiG Partition Manager and simple system tweaks, you’ll find a solution that works for your situation.

Method 1: Check PC Compatibility

Your computer needs Microsoft’s minimum specifications check as your first step toward Windows 11 installation. A PC's hardware compatibility with Windows 11 stands as the primary installation failure cause so checking it at the beginning prevents unnecessary time and resources from being wasted.

The system demands from Microsoft include a 64-bit processor and 4 GB of Random Access Memory and TPM 2.0 support and other specifications. Running this test lets you discover weak points so you can take action before moving forward.

• Go to the official Microsoft website and find the Windows 11 system requirements page.

• Download and run the PC Health Check tool from Microsoft to scan your computer’s hardware.

• Review the results; if your PC falls short, upgrade components like RAM or enable TPM 2.0 in the BIOS if possible.

  

Method 2: Remove 0xC1900101

The 0xC1900101 error code emerges during Windows 11 installation processes because it detects conflicts involving drivers or system hardware. A driver or hardware conflict might be the cause behind this problem which can originate from old graphics drivers, insufficient RAM or faulty BIOS configurations. The successful upgrade requires systematic solutions to these elements which will eliminate the error from occurrence.

• Disconnect all external devices, such as USB drives or printers, from your computer to avoid conflicts.

• Remove the GPU driver by opening Device Manager, expanding “Display adapters,” right-clicking your graphics card (e.g., Intel(R) UHD Graphics), and selecting “Uninstall device.” Follow the prompts to finish.

  

• Improve startup settings by pressing Windows + R, typing “services.msc,” and hitting Enter. Locate Background Intelligent Transfer Service (BITS), Windows Update Services, and Cryptographic Service. Right-click each, choose “Properties,” set the Startup type to “Automatic,” and click “OK.”

  

• Check your RAM; if it’s below 4 GB, add more memory to meet the requirement.

• Adjust BIOS settings by restarting your PC and entering the BIOS (usually via F2, F10, or Del). Find “Active Core Settings,” change the active processor cores to 1, then save and exit.

  

Method 3: Convert MBR to GPT

The installation of Windows 11 requires disks to use GPT partition format so MBR partitioned systems will not progress. The conversion from MBR to GPT through manual methods may delete all data however using 4DDiG Partition Manager creates a secure pathway for the shift. The tool permits file preservation during transitions through a convenient conversion process. This becomes an effective solution to resolve the installation issue.

• Download and install 4DDiG Partition Manager from its official website onto your computer.

• Open the software, select “Convert Disk” from the left panel, and click “Convert MBR to GPT” to start.

  

• Choose the disk you want to convert from the list, then click “Continue” to move forward.

  

• If it’s your system disk, the program downloads a PE component; save any open files and ensure a stable power supply.

• In the PE environment, select “Convert MBR to GPT” when the software loads. Pick the disk again and click “Continue” to begin the conversion process.

  

• Wait as 4DDiG Partition Manager converts MBR to GPT; the time depends on your disk’s partition count.

  

• Once finished, follow the on-screen instructions to ensure your computer boots correctly after the change.

  

Method 4: Run a Clean Boot Installation

Windows 11 installation may fail because background programs and services run during the process. A system clean boot requires only necessary system services while booting up because it minimizes boot-up interferences. Clean boot allows you to detect what could be causing software complications that prevent installation.

• Press Windows + R to open the “Run” dialog box on your computer.

• Type “MSCONFIG” and press “OK” to launch the System Configuration window.

  

• Click the “Boot” tab and uncheck “Safe Boot” if it’s selected.

  

• Switch to the “General” tab and select “Selective startup” from the options. Uncheck the “Load startup items” box to disable non-essential startup programs.

  

• Go to the “Services” tab and check “Hide all Microsoft services” to protect core system functions.

• Click “Disable all” to turn off remaining third-party services.

  

• Navigate to the “Startup” tab, click “Open Task Manager,” and disable each enabled item by right-clicking and selecting “Disable.”

• Enable each item one by one, click “OK” in System Configuration, and restart your PC.
