Windows 10: No System reserved partition in Disk Management, Windows cannot update

Hi, Whenever I try to look for updates through the Windows update program, It says my PC is up to date. However, My PC is still on build 1909. Updating through the media creation tool with an ISO gives the error "We couldn't update the system reserved partition." Looking at the Disk management screen, I don't seem to have a system reserved partition.

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.

cannot locate system reserved partition on Disk Management

I am trying to update Windows 10 and it keeps giving me an error and saying that "We couldn't update system reserved partition" I have gone into Disk Management but could not locate what the system reserved partition is. I would appreciate if someone
could point me in the right direction.

Thanks

 

Windows 10 Update can't update system reserved partition


This looks like a GPT initialized disk and UEFI firmware.

See Sample: Configure UEFI/GPT-Based Hard Drive Partitions by Using Windows PE and DiskPart for the default and recommended disk schema.

Your setup doesn't seem to have a Microsoft Reserved partition (different from System Reserved) - it has it's own type of MSR. This is a hidden part, so it might only be visible in Diskpart.

To cut down on any confusion, I would physically swap the drives so that
Disk 1 becomes Disk 0 and
Disk 0 becomes Disk 1.

It's just a matter of of pulling the connectors and reconnecting them to the other port.
After you have removed the bogus System REserve partition you created (as suggested by NavyLCDR) and swpped the drives,

Please post a new Disk Management screen shot:

Method One: Use Disk Management in the x-Menu (right click the Windows logo, select Disk Management)

Select View > Bottom > Disk list

Maximize the window and grab the screen shot.
Method Two: Use a custom MMC to present Disk Management with pertinent information

If you've already downloaded the custom MMC, go to Step 2 to launch it and then grab the screen shot.

Step 1: Download this zip file (contains dmDskmgr-vd.mmc)

dmDskmgr-vd.zip
Step 2: Double click dmDskmgr-vd.zip to open the compressed folder
Double click dmDskmgr-vd.mmc to launch the custom Disk Management console
You'll get an output similar to this:
