Windows 10 version 1809 update fails saying "We couldn't update the system reserved partition"

HP Recommended
Z240 SFF
Microsoft Windows 10 (64-bit)

Hi, when  windows update attempts to install the 1809 update on my PC, it fails as below. A google search suggests the system resersnip_20181003134505.pngsnip_20181003134544.pngved partition could be not large enough.

I've done the troubleshooting (both HP and MS) and no difference. I've also tried the instructions at [edit]

Any thoughts please?

Not only do I heartily support the recommendation that @erico made (to NOT continue to try to install the 1809 Upgrade); furthermore, I would so so far to recommend that even if MS comes out with a revised Upgrade today (which some pundits are predicting will happen), you wait a week (or more) to see how that plays out.

The rumours were that MS was informed IN ADVANCE of the problems with file deletions through the Feedback Hub that Insiders use -- and they chose to ignore those warning and go ahead with a premature release of the 1809 Ugrade anyway!

Which means, you would best being overly cautious with this Upgrade to see if a newer version actually fixes the issues and if it causes even new problems.  The improvements in the 1809 Ugpgrade are trivial, at best, and not worth risking your PC being trashed in the process.

Thanks. I'm not sure what the hidden system partition is, or the system reserved partition, but the image below shows the current status of the disks. I've tried many times to have Windows Update try and install the update but the same error message keeps coming up.snip_20181003215923.png

Microsoft has pulled the update to version 1809 due to the deletes files issue. 

 

It is highly recommended you  stop trying to update to that particular version.

Hi,

 

Also agree with WAWood and erico.

 

I am running 1809 on a Z370 MB with no problems.

 

But I have an 1803 installation image on external backup in case something bad happened.

 

Regards

An a habitual early adopter I did it again this time, and got lucky (so far), with 5 workstations "upgraded" to the 1809 version.  Wish I had waited, however, and will in the future.

 

Regarding that "system reserved" partition the amount the installers reserved for whatever that partition does has steadily increased.  If you do a clean install of W7 you'll see it was pretty small.  Then W8, and now W10 have raised the size quite a bit.

Clean installs of W10 will give a proper large system reserved partition.  Upgrades of prior OS to W10 does not, and that is how you can hit this issue.

 

There are utilities to shift partitions in size, taking from one and giving to another.  I have a utility that has a check box for doing the partition adjustments optimized for SSDs, which virtually all of us are using by now.  I'll dig that out and update here.
