    Let's remove some 3rd party drivers. Please run the fixlist below.

    • Download fixlist.txt
    • Save Fixlist.txt to the same folder as FRST64.exe.
    • Close all programs.
    • Launch the Farbar Scanner tool and click "Fix".
    • Restart Windows when prompted.
    • Upload the output log file (FixLog.txt) to your OneDrive.

    NOTE: The fixlist.txt script was written specifically for this user and for use on that particular machine. It is not recommended to run it on another machine, and don't run the same fixlist.txt more than once.


    The fixlist removes some old drivers, runs a drivers assessment, and refreshes the compatibility assessment. Your browser's cache and cookies will also be cleared.


    The following drivers will be removed.

    cpuz161
    
    dg_ssudbus
    
    googlehaxm
    
    sprdvcom
    
    ssudmdm
    
    UsbDk  (Red Hat, Inc. -> Red Hat Inc.)

    That specific error (0xC1900101 – 0x20017) almost always points to a driver or firmware issue that stops Windows from rebooting into the next setup stage. The black screen during the reboot is a big clue.

    A few things you can try that usually fix this:

    1. Disconnect everything you can. Unplug USB drives, external HDDs, printers, adapters, etc. A bad USB/driver can stop the SAFE_OS boot.
    2. Update BIOS/UEFI. If your BIOS is outdated, Windows setup can fail at exactly this step. Check your motherboard/laptop manufacturer’s website for the latest version.
    3. Remove or disable third-party drivers. If you have things like old VPN drivers, antivirus, RGB software, or leftover GPU drivers, uninstall them. In BIOS, temporarily disable things like:

    Fast Boot

    Secure Boot (you can re-enable later)

    CSM/Legacy Mode (set to UEFI only)

    1. Try installing with only one stick of RAM. It sounds odd, but faulty or mismatched RAM can trigger this error during the SAFE_OS phase.
    2. Recreate your installation media. Use the official Media Creation Tool to make a fresh USB. Corrupted install media can cause the exact black-screen behavior you described.
    3. If the PC blacks out even on Reset This PC. Boot into Advanced Startup → Command Prompt and try:
    sfc /scannow
    DISM /online /cleanup-image /restorehealth
    
    

    This sometimes fixes the boot files enough for the installer to continue.

    If you can share your exact PC model and whether the black screen has a cursor or stays fully blank, it’ll be easier to pinpoint what’s blocking the install.

    Based on the FRST file, I have noticed that you have installed KMSpico. If it is still available, please uninstall it. If you installed third-party antivirus software, uninstall it too. Have you tried performing a clean install instead of upgrading it?

    Note: Back up your important files if any.
