    We couldn't install Windows 10
    0xC1900101 - 0x40017
    We've set you PC back to where it was right before you started installing Windows 10
    The installation failed in the SECOND_BOOT phase with an error during BOOT operation

    What was tried: Connected straight to ethernet, Turned off wireless and Defender A/V, Removing the D/L files, D/L fresh from ISO file, launched install file, went through approx 50% and PC rebooted - nor stuck on black screen with swirling dots for OVER 4 hours with a brief HD access every couple of seconds.

    Rebooted again -- still swirling dots on black screen. Tried again, same results.

    Rebooted with F8 to get original Win 10 back.

    Turned on "metered connection" option for WLAN to stop this update from happening. But now I cannot get and security updates for this machine.

    Please suspend this D/L until fixed. Cannot afford to have no protection!

    That's a fan forum, not linked to Microsoft. Update works fine.

    I removed the wireless devices in the USB ports. Those were for the mouse and keyboard.
    Then the update went flowless.
