    Windows 10 without system reserved partitions


    Hi can anybody please explain these two questions:
    A- How many are the partitions that windows 10 automatically creates during installation, what are they for and what is it stored in them?
    B- if I choose not to have them (for example by creating the windows partition with another software before installing windows 10) are there drawbacks, does windows run exactly the same as having them?
    thank you!

    :)

    cannot locate system reserved partition on Disk Management

    This Windows 10 upgrade error is usually caused by insufficient space on the System Reserved partition. When you install Windows to a partitioned MBR disk, Windows will create an additional partition without drive letter labeled as System Reserved, which
    stores important boot files and normally locates before the system partition (often known as C: drive). On Windows 7, it often takes 100MB disk space, 350MB on Windows 8, and 500MB on Windows 10. Since upgrading to Windows 10 needs more space on the System
    Reserved partition, Windows 10 will not upgrade unless it detects that the System Reserved partition has enough space. If you fresh install Windows 10 to a specific partition, you won't receive this error. By the way, the System Reserved partition first appearance
    was on Windows 7, so you won't have this error on previous versions of Windows.

    To solve this problem of being unable to update System Reserved partition, you can increase the size of System Reserved partition using third party free partition software like AOMEI Partition Assistant Standard, which can manage your disks and partitions
    without data loss.

  3. No System Reserved Partition After Free Upgrade and Clean Install of Windows 10 Pro x64

    I don't think the proposed solution applies to my problem. The Windows 7 system upgraded from didn't have system reserved partitions. So the system reserved partition can't be inadequate it didn't exist. Also, the system partition was formatted during the
    clean install so any existing system reserved partition would have been deleted. No errors were encountered during the upgrade and Windows 10 seems to work fine.

    What I'm trying to do is determine is how to add a system reserved partition for the Windows 10 system without one. From what I've read each Windows 10 system should have a system reserved partition. Do I just need to redo the clean install?

    Thanks.

    Here's the typical Win 10 UEFI partition layout:
    UEFI/GPT-based hard drive partitions

    The System partition -16Mb
    What is the System Reserved Partition and Can You Delete It?

    The Recovery partition - 450Mb- supports automatic repair and Advanced Troubleshooting tools.

    EFI partition: (shown as MSR above) - 100Mb

    These are small - why would you go to the trouble of thinking about removing them anyway?

    Note the partition layout for legacy BIOS based Windows 10 is different.

    Some people have had problems with Windows Updates failing when they have not had the standard System partition they were booting from.

  7. I use a legacy BIOS and I have only one partition. Windows creates a recovery partition but I delete it and extend drive C:\. If I recover anything I use Macrium Reflect to do it.

    Windows 10 without system reserved partitions

    This question is unanswerable, because it starts with a false premise. The number of partitions created by Windows varies depending on the type of BIOS and/or type of boot being done. If you boot using a legacy BIOS, only one partition will be created. If you boot from an EFI bios using an EFI boot, then it will create 3 by default. A 4th partition is possible, for recovery, but it is not automatically created by default.
