Windows 10: Windows 10 won't boot, black screen with blinking underscore

    Windows 10 won't boot, black screen with blinking underscore


    So my pc stopped working on Monday I've spent the past couple of days trying to figure out how to fix it but haven't found anyone else that's having the same issue as me. Monday morning I booted up my pc and was got a black screen with a blinking underscore at the top left. I have my most important stuff already backed up so that's not an issue.

    ​My problem comes from not being able to use most of the "commands" in the startup menu. So I can't follow other threads and fix my problem.

    Continue Startup, Diagnostics, Boot Menu and network boot all lead to the same black screen with the blinking underscore at the top left corner. Diagnostics gives me another option "dps self- test" It can detect my hardrive and the tests said that everything was fine.Utilities lets me set the time and date and "flash system rom" though I can't actually scroll down to that second option. I also can't scroll down to the "Run UEFI Application..." Pressing ctrl + s and F10 take me to computer setup though i'm not sure what I can do with that.

    ​My computer specs are

    ​hp Compaq 6200 pro sff pc
    ​Geforce 610
    ​Intel (R) Core (TM) i5-2400 CPU @ 3.10ghz
    ​Running windows 10 though it originally ran windows 7
    ​Satao 250 GB, Hitachi

    ​I usually have a second hardrive for my steam library but I've disconnected that, as well as everything else other then my mouse, keyboard and monitors.

    a blinking underscore at the top left.
    Typically that means you have no access to your hard/system drive.

    Try booting your PC from a boot disk and see if you can see anything of your drive.
    E.g. Kyhi's very useful boot disk - available from the top of the Software and Apps section here (Win 10 + utilities)
    Have a look inside and check the connections- wiggle any relevant connectors.

    Hopefully you have full backups - and if you follow our constant recommendations, use disk imaging routinely.
    If you've been doing that, and you need to get a new disk, you can restore a disk image to it and be back up and running quite quickly.
