    dual boot with win 7 & 8.1 - how to uninstall 8.1?


    I hated 8.1 after I installed it a year ago. Now want to dual boot win 7 & 10 - How can I safely uninstall 8.1?
    And then can I do a dual boot - 7 & 10, getting the win 10 download via the update?

    You could remove the partition for Win 8.1, then you should just have Win 7. Believe the letter of the law (EULA) you can't use Win 7 and 10 on the same license, there's been much discussion on that since physically a dual boot wouldn't allow you to run both at the same time. IMO MS never intended W10 upgrade to be a "two for one", it's one or the other. When you change to W10 your license is then associated with that OS.

    UPGRADE your windows 8.1 installation to windows 10

    Thus keeping the dual boot = windows 7 and now windows 10

    Better off upgrading using the ISO method..
