    Windows 10 upgrade failed twice


    I have just failed miserably to upgrade my Acer E5 laptop running fully updated Windows 8.1. The error code and message read
    0xC1900101-0x40017 Failed in SECOND-BOOT phase. Error during BOOT operation.

    Can anyone supply some possible causes and/or solutions please?

    This error is usually associated with a USB device. Try unpluging all USB devices as a troubleshooting step and try the upgrade again. If the upgrade is then successful, you can plug the devices back in and they should function normally.

    Thanks for the input. I made sure all USB devices were disconnected and tried to upgrade again. I got the same result, no install.

    Next thing to try is to make sure you have all the latest drivers for the system, check on the Acer support pages for your model. In particular, make sure you have the latest BIOS installed.

    As with all problems of this nature it is a matter of trial and error and systematically working through the possibilities.
