Assistant finishes the 3 steps, reboots, blue install screen comes, percentage goes up normaly with time, then another reboot, and I get the installation has failed message, and then shortly after the 0xC1900101 code in the assistant.I tried running sfc scannow, chk dsk, etc. commands, nothing helps. Every driver and BIOS is up to date, system SSD has more tha

    Windows 11 upgrade fails error code (0xC1900101)

    finally solved after lots of tries:

    • remove other users on computer.
    • download & install lenovo drivers for win 11 from lenovo site.
