    Windows 10 missing after installed Windows 7


    Today the day became worst when i format my windows 8 to installed windows 7, then i found i am not getting the dual boot option for Windows 10. I tried startup repair through windows 10 dvd but it is only showing win 7 for repair, no windows 10??

    Both OS partitions were different C and D. I can see Windows 10 files are still in D drive.

    How can i get back my Windows 10 again... i lost it somehow.....

    Hi, from what I understand from other's experience of this, Win10 startup repair will not work in such a scenario.
    Try this:
    Dual Boot Repair Tool: Repair BCD Boot Configuration Data
    and some have used this:
    BCDEDIT - How to Use - Windows 7 Help Forums

    Run the following commands at the command prompt.

    diskpart
    list volume NOTE: Note the volume letter where the Windows OS is installed.
    exit

    bcdboot X:\windows NOTE: Replace "X" with the volume letter of the Windows OS partition.

    The following is an example if you have a dual-boot system installed.
