    System Reserved?

    Hi All
    Have been trying to find out, in Disc management why I have one HDD showing it System Reserved. I think it was my old system drive and may have had Win 7 on.
    Many Thanks for any help

    System partition and boot partition - Wikipedia, the free encyclopedia

    System partition and boot partition are computing terms for disk partitions of a hard disk drive that must exist and be properly configured for a system to operate correctly. There are two different definitions for these terms: Microsoft definition (used by Windows) and the common definition used by every other operating system.
    Microsoft defines the terms as follows:

    • The system partition is a primary partition that contains the boot loader, a piece of software responsible for booting the OS.[4] This partition holds the boot sector and is marked active.[5]:970
    • The boot partition is the disk partition that contains the operating system folder, known as system root or %systemroot% in Windows NT.[6]

    A single partition may be both a system and a boot partition. In case they are separate, however, the boot partition does not contain the boot software and the system partition does not have the system root.[5]:971
    Before Windows 7, the system and boot partitions were, by default, the same and were given the identifier "C:". After Windows 7, however, Windows Setup creates, by default, a separate system partition that is not given an identifier and therefore is hidden. The boot partition is still given "C:" as its identifier. This configuration is suitable for running BitLocker, which requires a separate, unencrypted system partition for booting.
    If you want to fix this, and you know what you are doing.

    Step One:

    Delete the System Reserved partition. edit: In this case, wipe the entire disk.

    - Boot the computer using the Windows 7/8/10 installation media.
    - On the first screen, press SHIFT+F10 to bring up the command prompt.
    - Run the following commands at the command prompt.

    list disk (this will give you a listing of the disks on your system)
    select disk # (select the disk you want to clean)
    clean (running the clean command will delete all partitions on the disk)

    Step Two:

    When I loaded win 10, I only had the 250Gb ssd drive connected, if I leave it as it is, I loose a full 500Gb drive?

    It looks like that system reserved partition on the last disk is where the BCD store is located, because it is marked active. What I would do is shrink the partition to 350mb then create your data storage partition after it to use the rest of the space.

    From your screen shot. If you disconnect disk 4 from the PC, you will not be able to boot up Windows. Here's how you can fix this problem.
    Download : EasyBCD - NeoSmart Technologies
    Install then run and follow the screen shot below:

    Temporarily disconnect disk 4 then try to boot again. If it's working, connect disk 4 back and from Admin command prompt:
    1. diskpart
    2. select disk 4
    3. clean
    4. exit

    Now open disk management, create simple and format it. You'll have the whole disk for data.
    Hope this helps !!!
