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


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

    warning   Warning
    You will need to have the Microsoft System Reserved Partition.



    Part One

    Here's How:


    1. Start or restart your PC, and boot into Windows 8. (see screenshot below)

    2. Open Disk Management by typing diskmgmt.msc in search bar. (see screenshot below)

    Click image for larger version

    3. In Disk Management, delete the partition that you installed Windows 7 on so that is is now unallocated space. (see screenshots below)

    4. If you like, you could either create a new partition to use with the unallocated space, or extend the Windows 8 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.

    Note   Note

    5. When finished, restart your PC and only have Windows 8 installed and listed in the Windows Boot Manager screen.

    Hello cycledoc,

    My guess would be because of the new Windows 8 boot GUI.

    I extend the old Windows 7 System Reserved 100mb partition, to be same as the new Windows 8 System Reserved 350mb partition.

    Windows 8


    I purchased a Windows 8 upgrade and presently dual boot with Windows 7. I am ready to commit to Windows 8, remove any windows 7 partitions, and expand the Windows 8 partition to recapture that disk space. This tutorial seems to be what I need, but I am concerned that the present Windows 8 partition is not Primary, and I fear leaving the system unbootable. I've used EaseUS to get where I am now as shown here:

    I'm not sure how to proceed. Thanks in advance for any help you might offer.
