    Help - Can't open Windows 10! (I have ubuntu 15.04)

    I tried boot-repair, it does nothing.
    When I choose windows10 on the start up, it gives me a blue error page.

    "Your PC/device needs to be repaired.

    A required device isn't connected or can't be accessed.

    Error code: 0xc000000f

    Press F8 to go to startup
    PRess enter to try again
    Both of those do nothing.

    It says winload.exe is missing or corrupt, i only have ubuntu atm.

    All help is appreciated :)

    i think that ubuntu overwrote windows.

    it sounds like it (ubuntu)did, you need to boot to win10 media and run the repair to see it it will fix the boot issue

    When you start Ubuntu can you see the Windows folders anywhere? Linux operating systems can see all your Windows stuff. If nothing from Windows is visible, then you probably overwrote your Windows operating system and will have to reinstall.

    No windows folders show up.
    I have a usb with windows 10.iso burnt on to it but when I set BIOS to run as USB it does nothing.

    Try booting from Windows 10 repair disk and running in Command Prompt:
    bootrec /fixboot
    bootrec /fixmbr
    bootrec /rebuildbcd

    This happens when you move the Windows partition or modify it some way, usually, but it could also happen if you replace the bootloader.

    I can't run any ISO.
    I've tried to but none worked.
    I don't have any repair disks

    Many people have broken dual boot systems by installing windows 10. Windows 10 does not recognise other non windows boot loaders.

    General advice is to install windows 10 to a blank drive, then install Linux afterwards.

    You can download windows 10, creating a usb stick from MS web site
