    Remove Extraneous Partitions on HDD Boot Drive Windows 10


    So I used the Windows 10 installation media to put the Windows 10 installation files on a flash drive, and the installed Windows 10 onto my Samsung Series 7 Chronos laptop (it's old, it originally shipped with Windows 8; not 8.1, 8). After the installation, I went into the Disk Managment and noticed this:

    Notice all of the partitions on the C drive! I don't know how they were created and which ones are important, but I'm fairly confident that most of them DON'T need to be there.

    Unfortunately, Disk Management will not let me remove any of the 6 partitions directly, and I'm pretty sure that it should only have 3 partitions, one for Windows Boot Manager, one for my files, and the other one created by Samsung for system recovery. Unfortunately, I have NO idea which partition corresponds to what (except the 900 GB one being for my operating system, obviously), and I honestly don't know how to remove the extra ones that I don't need.

    How can I determine which partitions of this hard drive that I don't need, and how can I actually get rid of them?

    For reference, my specific laptop's model number is NP700Z5C-S02UB if that helps.

    Hi, it's not worth bothering about.
    An EFI configuration normally consists of 4 partitions (one of which is not shown by Disk Management). Of the smaller Recovery partitions, one will be the current one. The large one will presumably be your factory reset partition.

    The saving in space is not worth the trouble, unless you wish to delete the manufacturer's factory reset partition.

    You can identify the current recovery partition using the following commands (this is an indication only) from an admin command prompt:

    reagentc /info
    and
    diskpart
    - and its subcommands.

    Manipulating these partitions can best be done with a 3rd party tool such as
    Minitool Partition Wizard
    or
    Aomei Partition Assistant

    If you are unfamiliar with these tools ensure you have a current disk image before doing anything. (We constantly recommend Macrium Reflect (free) + external storage for routine use by almost all users).

    It seems you have multiple MS recovery partitions and an OEM recovery partition. Use MiniTool Partition Wizard to peruse the file dates of the MS recovery partitions and delete all but the latest one. Else you can use reagentc /info to locate the current recovery partition e.g.

    In my case it's partition 3 - but double check with MiniTool Partition Wizard.

    I decided not to bother with my OEM recovery partition and deleted that too since I use Macrium Reflect for system backups / recovery.

    Once you are done deleting partitions then you can use MiniTool Partition Wizard to move / resize the main C: partition. Please backup up your system before you start fiddling with partitions.
