    black screen with blinking line in upper left corner

    Hi, suggests it's not seeing your disk at all - nothing to boot from.

    Check your connections, check your disk - e.g. using a live boot disk or connect it to another PC.

    If you can manage to read it again, run chkdsk on it.

    Actually looks more like BOOT sector error, if disk wasn't working at all it would ask for "Bootable disk" or something like that depending on BIOS.
    Check BIOS to see if disk(s) are detected.

    Try this:
    1. Make sure you have Window 10 install disk or bootable medium e.g. flash drive that matches your current Windows build.
    I'll assume it's a DVD.
    2. Open your disk drive if it's a DVD
    3. Insert DVD
    4. Close disk drive
    5. Make sure you know how to get your PC to boot from said DVD
    6. Do a startup repair
    Startup Repair - Run in Windows 10 - Windows 10 Forums

    If you're very lucky, your problem will be fixed. If not please post back.

    But it should tell you if it sees your HDD or not.

    If any of the terms I used are unfamiliar to you, Google or other search engine will help.

    CAPITALS ARE UNFRIENDLY.

    Sorry.
    I do not have any windows 10 disk. I got windows 10 as a free download/upgrade.
    My pc does start up, meaning: black screen with some start up informations as it always has done. After a short period, I have black screen with blinking line (Cursor?) at upper left corner.
    Thanks for your assistance.
    Best regards, John
