    I have a hd with win10 and win7. Cannot delete win7 partition

    I have a dual boot with win10 and win7 on the same 1TB HD. Disk management will not allow me to delete the win 7 partition. I need that disk space back! Delete is greyed out. How can I get around this problem?

    First, please post a screenshot of disk management and make sure to drag the columns wider so we can see all the data in the columns:

    It might be that your boot files are also on the Windows 7 partition.

    Have you tried a third party tool, like the free version of MiniTool Partition Wizard (MTPW)? But first, as NavyLCDR says, you must make sure that you won't be shooting yourself in the foot, and making your system unbootable if you do delete that partition. Because you're messing with boot stuff (the easiest pathway to an unbootable system, when things go wrong), make sure you've got a current image backup and a bootable recovery device or DVD prepared before you start messing about.

    Your computer is currently booting from the Windows 7 Pro x32 partition. Delete that partition and you will break booting. Use EASYBCD to move the boot files to the Windows 10 partition. The System and Active flags inside the parenthesis of the Windows 7 partition is what indicates that is where the computer is booting from.

    Changing the Boot Partition

    After you change the boot partition, reboot the computer. Go back to disk management and make sure the Active and System flags move to the Windows 10 partition inside the parenthesis. Then delete the Windows 7 partition.
