    Dual boot Win7 & Win10 on same HDD - How to eliminate Win7?


    I had a single hard drive with Windows 7 on it and then created another partition and loaded Windows 10 on that resulting in a dual boot setup.

    I want to eliminate the dual boot setup and delete the partition with windows 7 on it leaving a single partition with only Windows 10.

    How can I do that without totally messing up the MBR and the booting process?

    Thanks!

    command prompt:

    diskpart
    sel vol c:
    act
    exi

    bcdboot c:\windows /s c:


    Then reboot your pc.

    next is the interesting bit. You will be able to delete the win 7 partition in disk management, but you need a 3rd party tool to extend the win10 partition to the left.

    Partition Manager Software: Partition Magic Alternative for Windows PC and Server | AOMEI Partition
    Assistant


    Install the free version of aomei, get it make boot media and use the boot media to do the partition extending.

    Worked like a charm. Command used was "bcdboot C:\Windows /s C:"

    Thank you so much!
