    How to Delete "Windows 8" in your Dual Boot with Windows 7 or Vista

    information   Information
    This tutorial will show you how to delete Windows 8 in your dual boot with Windows 7 or Vista when Windows 7 or Vista was installed first and Windows 8 installed second. This will leave you with only having Windows 7 or Vista installed afterwards.



    Part One

    Here's How:


    1. Start or restart your PC, and boot into Windows 7 or Vista. (see screenshot below)

    2. In Disk Management, delete the partition that you installed Windows 8 on so that is is now unallocated space. (see screenshots below)

    3. If you like, you could either create a new partition to use with the unallocated space, or extend the Windows 7 or Vista C: drive into the unallocated space to add it back to the C: partition. (see screenshot below)
    NOTE: This will vary depending on how you have your hard drive setup though.

    4. When finished, restart your PC and only have Windows 7 or Vista installed and listed in the Windows Boot Manager screen.

    Part Two

    When you have your Dual boot on a PC with a uEFI setup.

    Probably a dumb question but.. does the unallocated space join back with the main OS partition or do you have to manually do it somehow?

    You do it manually.

    Rt click the win 7 partition and select Extend.

    You can extend or create new partition.

    Would this tutorial work with VHD partitions too? I followed the tutorial here to create a VHD:Windows 8 VHD - Create at Boot to Dual Boot with
    I'm assuming to remove Windows 8, I just have to delete the VHD it's installed on.

    Hello Nonpasaran,

    When you delete the Windows 8 VHD or partition from within Windows 7 and restart the computer, you do not need to do that since it is removed automatically when you restart.

    OK.

    I asked because 1 month ago I was use Window 7 HP and Ultimate as dual boot. Accidentally I deleted the Ultimate partition and after then unable to boot Home pre.
    With 3 or 4 startup repair could fix it

    Thank you Bring

    Thanks for the answer. I was wondering, What are the benefits of installing Windows 8 on a VHD instead of a normal partition? I just installed it on a normal partition.
