    Delete my W10 Partition

    Do you want to safely delete your Windows 10 partition and use only Windows 7?

    If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :

    Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
    Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.
