    How to expand System Reserved partition to accept Windows 10 1709.


    In an effort to get 1709 update to install, one of the "solutions" that has been suggested is that is should expand my current 100 MB NTFS System Reserved partition from its current 100 MB to 550 MB ( the cause of the Oxc1900200 error). However, when I research how to expand a partition, I find that it states that there must be unallocated space into which to expand the partition. I have no unallocated space. My drive is as follows:

Views:	75 
Size:	92.8 KB 
ID:	181222

    My current drive is Disk 0.
    I tried taking some of the room (450 MB) on the eMachines (C: ) partition which could be combined with the System Reserved partition to make 550 MB System Reserved. However, when I took some space (450MB) from eMacines (C: ), for a new partition (F: ), the drive crashed, would not boot. I ended-up rescuing it copying a clone to it.

    So my question is: How do I make space on my disk 0 so that I can increase the System Reserved partition to accommodate the installation of Windows 10 Pro 1709?

    I'd boot my PC from e.g. Minitool Partition Wizard's boot disk.
    Then decide if I needed to keep the manufacturer's recovery partition. If not, delete that, and adjust the other partitions accordingly.
    If I wanted to keep it, then shrink C: and expand the System Reserved partition.

    When you say it failed to boot- in what way?
    You might find it tries to run Automatic repair to sort itself out.
    If that doesn't kick in, then boot your PC from Macrium Reflect's boot disk and use its Fix Boot utility.

    I wouldn't have two presumably bootable disks in my PC at the same time.

    When you say it failed to boot- in what way?
    When I ran the Aomei Partition Program's command to do the partition, it ran for 23 hours and then crashed. The disk would not boot, no matter what I tried. It locked-up and I had to shut the power off.

    I wouldn't have two presumably bootable disks in my PC at the same time.
    I do not. What you see in the screenshot (Disk 1) is a clone sitting in a USB dock. The power was "on" to the dock when the screenshot was taken. Normally, the power is off and it would not show up in the Drive Management program. For the purpose of this discussion, you can just ignore the existence of Disk 1.

    I'd boot my PC from e.g. Minitool Partition Wizard's boot disk.
    I do not have one of those. I would prefer to use Windows 10 Drive Management system.

    Then decide if I needed to keep the manufacturer's recovery partition. If not, delete that, and adjust the other partitions accordingly.
    How would I know if I wanted to do that...or not? I need more information...not an abstract.

    If I wanted to keep it, then shrink C: and expand the System Reserved partition.
    A step-by-step would be helpful. When you give an abstract (a summary), you have a frame of reference in your mind (can envision the steps in what you are saying), I do not.

    That's where you are mistaken. To do this, use a boot disk from a 3rd party partition manager, or use a 3rd party partition manager which will apply the changes when your PC is restarted.

    Experts here state they would never attempt to use Disk Management to make changes to Windows partitions.

    Read the guide /help for the one you use.
    Using such things is usually a matter of dragging sliders- the picture of the partition boundary.
    It might take a couple of steps.

    It's your choice!!!!
    If you ever want to restore your PC to the state it was in when you bought it, keep it.
    If you don't want to restore your PC to the state it was in when you bought it, delete it.

    1.Shrink your C partition ( from the right) by about 600 mb.
    2.Create a new partition from that unallocated 600mb.
    3.Give your newly created 600mb partition a drive letter, e.g. S.
    4. Give the 100mb partition a drive letter, e.g. Z
    5. Open an elevated command prompt type:
    diskpart
    sel vol z:
    inact
    sel vol s:
    act
    exi
    bcdboot c:\windows /s s:

    1.Shrink your C partition ( from the right) by about 600 mb.
    Using what program? I assume it has some kind of slider bar?


    2.Create a new partition from that unallocated 600mb.

    3.Give your newly created 600mb partition a drive letter, e.g. S.
    Right...will name the new partition drivel letter "S".

    4. Give the 100mb partition a drive letter, e.g. Z
    Will change old 100MB partition (System Reserved) to drive letter "Z".

    5. Open an elevated command prompt type:
    Right-click the start button, click on "Windows PowerShell (Admin)".

    diskpart
    Type "diskpart", hit "enter"?

    sel vol z:
    Type "sel vol z:", hit "enter"?

    inact
    Type "inact", hit "enter"? (makes vol z: inactive)...Whoa! "vol" z:?! Not "partition" Z:?

    sel vol s:

    act
    Sets vol s: to active. But there is that "vol" thing again...volume or partition?

    exi
    I assume you meant "exit"?

    bcdboot c:\windows /s s:
    I am sorry, but your instructions are too imprecise to trust. Bad instructions are worse than no instructions at all. I cannot be sure that you know what you are doing...sorry. I don't want to mess up my computer.

    When I bought the computer (refurbished/used/from a reseller), I came with Windows 10 Pro. I have been told that the reason for my partition arrangement (15/100/C: ) is that it was upgraded by the refurbisher to Windows 10 Pro from Windows 7. My wife's computer has a 350 MB System Reserve partition, indicating (I was told), that hers was likely upgraded to Windows 10 Pro from Windows 8. I anticipate that I will have to upgrade Windows Pro, beyond the 1709 build at some time in the future. Therefore, I do not anticipate ever going back to the 15/100/C: arrangement inasmuch as some have told me that 1709 needs more (550MB) than a 100 MB System Reserved partition to operate.

    Hi,
    Just use mini tool :)
    Reduce the 15gb partition if it has free space.

    Evidently, it seems too much to expect an explanation (Is a Recovery Partition not needed?) and then a step-by-step process.

    Let me start over. How should I partition my drive to be able to install Windows Pro 10 build 1709? That is, what size, what should they be named.
