    Clean install - how to manually create the special partitions


    I want to clean install Windows 10, and I already did that before using the tutorial here.
    But last time I did not have Ubuntu install.
    And in the tutorial, you must delete all partitions in order for Windows to create the special necessary partitions (Recovery, MSR, MBR etc..)
    But now that I have a Linux partition that I don't want to delete, and according to the tutorial, Windows installation will not create these partitions.

    How can I manually create them? Is it simply allocating a space for them and naming them the proper way and Windows will know how to use them? Or there's more than that?
    Also, What happens if I do not have these partitions?

    Thanks!

    :)

  2. Needs two partitions to boot

    You don't need to create any partitions manually to install Windows 10.

    Windows 10 setup automatically creates a system reserved partition during setup for storing recovery files.

  3. Windows 10 - Create SYSTEM partition (update to 1607)

    Sorry, but you've got me completely wrong.

    I'm not asking about how to partition my drive to save some data (like discussed in refer topic), I'm asking how to
    simulate specific partition technic, usually performed automatically by windows installation media. Or which unusual specification should have manually created partition,
    to be recognized as windows "system" partition (like it's size, file system, flags, special records (mbr, bsd) etc.)

    Clean install - how to manually create the special partitions

    You don't have to delete all partitions. As long as you leave the partition unallocated (excluded UBUNTU partition) then Windows should create all needed partitions.
    NOTE: If you install Windows with UBUNTU already existed, Windows is not aware of UBUNTU. You would need to use EasyBCD to create a boot entry for UBUNTU for dual booting.
    Do you use Macrium to backup Windows ? If so, you don't need to re-install Windows. Just use Macrium to copy all Windows partitions back to the SSD/HD unless your Windows 10 does not function properly and you want to re-install.

    If the computer has an UEFI bios with secure booting, will that work?

    Never have any use for Secure Boot enabled so if it does not work, just temporarily disable it. I doubt if the OP has Linux installed on a GPT disk since it is more complicate to setup ie. creating extra partitions on Linux to set up to work with GPT disk.

    Personally, I don't use dual boot, always set up Windows/Linux on separate SSD/HD with its own Boot Manager and use Boot Menu to boot from.
