    the cause to your problem is probably a corrupted MBR or BCD file. so you have to fix MBR or rebuild BCD.
    you have two ways to fix:

    Command Prompt:

    boot computer from your recovery drive, select “Troubleshoot”> “Advanced options”> “Command Prompt”. then type below commands in return.

    BOOTREC /SCANOS
    BOOTREC /FIXMBR
    BOOTREC /FIXBOOT
    BOOTREC /REBUILDBCD
