    If you post a screen shot of Disk Management then I'll be able to help you:

    So I tried this, and this is what it says.
    “Startup Repair couldn’t repair your PC”
    “Press ‘Advanced options’ to try other options to repair your PC or ‘Shut down’ to turn off your PC.”
    “Log file: C:\Windows\System32\Logfiles\Srt\SrtTrail.txt”
    And it gives me two buttons to press: Shut down or Advanced options.

    Your EFI System contains the Grub Boot loader. We need to rebuild this partition to get back the Windows Boot Manager.
    Download: MacRescue.iso - Google Drive
    Format a USB stick with FAT32 then extract the ISO to the stick using 7-zip. Boot up with the USB.
    Open Admin command prompt on the bottom left and type:

    diskpart
    select disk 0
    select partition 1
    format fs=fat32 quick
    exit

    From Macrium screen, click on fix Windows Boot problems
    Click Next
    Reboot

    NOTE: This screen is from the old version. The new version looks similar.

    Google Drive can't scan this file for viruses.

    MacRescue.iso (251M) is too large for Google to scan for viruses. Would you still like to download this file?
    Download anyway not working.

    What do you mean it's not working ??? This MacRescue.iso was created from Macrium Reflect. Double click on it, it should mount to a virtual CD/DVD.

    BTW, instead of using 7-zip to extract the file. Just copy the content to a USB stick then boot up from it.

    Here's the screen shot of MacRescue.iso:
