    Windows 11 is here and many users are eager to test it. However, it seems that some of them are experiencing various issues while trying to install the OS.

    The procedure should be straightforward, and all that you need is Windows 11 installation media and a PC that meets the hardware requirements.

    However, various issues can sometimes occur, and in this guide, we’re going to show you how to solve them instead of thinking that it’s time to uninstall Windows 11.

    But first, let’s see what to expect in order to determine what you’re up against. Just take a closer look below.

    What are the most common Windows 11 installation problems?

    • Installation has failed no error code
    • Windows 11 installation has failed ISO
    • Windows 11 installation has failed 0xc1900101 (Users with insufficient disk space on their devices are more likely to encounter the error 0xc1900101 in Windows 11).
    • Setup installation has failed
    • Windows 11 installation has failed safe_os phase (The Safe OS installation error can be solved by adjusting your RAM capacity or by upgrading the BIOS).
    • Setup has failed to validate the product key
    • Windows 11 keeps failing to install

    What are the minimum hardware requirements?

    Windows 11 comes with a different set of install requirements, and even if you were able to run Windows 10, you might not be able to run Windows 11.

    To make sure that you don’t encounter any issues, we encourage you to check the official Windows 11 requirements before upgrading.

    The hardware requirements aren’t that different, and the biggest change is the need for a TPM 2.0 chip, which some older PCs don’t have.

    If your computer meets the Windows 11 install requirements, you’ll ensure that the upgrade process is smooth and without any issues, and you’ll avoid the dreaded This PC can’t run Windows 11 message.

    How can I fix Windows 11 installation problems?

    1. Enable TPM in BIOS

  • Access BIOS/UEFI on your PC. This procedure is different for each manufacturer but usually implies pressing an F (function) key on your keyboard before booting the OS.
  • Now go to the Security section.
  • Locate the TPM option and enable it.
  • Finally, just save all recently made changes. Usually, you can press the F10 key to save and exit.

    • Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

    Keep in mind that this process is different for each motherboard model and version of BIOS, so you should check your motherboard manual for detailed instructions.

    Since Windows 11 requires TPM 2.0 to be enabled, many reported that TPM 2.0 errors are preventing them from installing Windows 11.

  • Click the Start button and select Settings.
  • Choose Update and Security.

    3. Bypass TPM 2.0 and Secure Boot

  • Press the Windows key + R to start Run, type regedit and press Enter or click OK.
