Windows Recovery partition missing from Volume list of Disk Management

Ooops!... That might explain it. Mine was OK in 18363.657 as I don't remember looking at it in 18363.697.
So it might be that MS broke Disk Management.

You could uninstall the last Win 10 Update.

I could...if it allowed me!

A windows update was just performed.
It is now 10.0.18363.720.







Diskpart displayed 6.98 GB
diskpart det partition displayed 7148 MB Fs RAW
reagent /c displayed disabled
reagent /c enable displayed The Windows RE image was not found.

So it appears for now that this new problem is related to Windows updates.

Isn't that wonderful... It seems that my "display" issue, is minor compared to this one, which displays Recovery partition correctly!

@ddelo
What I see with Partition 4 - which is clearly the Recovery Partition
WinRE is present and WinRE is registered....
With that said - the GPT Attributes listed by Powershell are slightly off for that partition
and should be > gpt attributes=0x8000000000000001
rather then current > gpt attributes=0x8000000000000000

change final digit to 1 and verify the results

Not sure if reason - but the partition is set to a different then normal Attrib
and I know that changing the 8 or final digit in the past had an effect..

As I said before...since Jimmy is here, if there is a a solution, it will be given!

As Jimmy suggested changing the last bit of the partition's attribute from 0 to 1 (made the partition Required), takes care of the problem.
The question is, why this should be done as the partition's attribute was never changed from what the Windows 10 installation set it and it was functioning perfectly before...but I guess that is something MS has to answer!!

Just to make clear what needs to be done, in case someone else faces the same issue:

Before:


After running the following diskpart coammands:

Code:

list disk
select disk 0  <-- the disk with the Recovery partition
list part
select part 4  <-- the Recovery partition
detail part
gpt ATTRIBUTES=0x8000000000000001

A huge thanks to Jimmy for his precious help!!!

And one last, more technical, note:
GPT attributes
- 0x0000000000000001. Specifies that the partition is required by the computer to function properly.
- 0x8000000000000000. Specifies that the partition will not receive a drive letter by default when the disk is moved to another computer or when the disk is seen for the first time by a computer.

For EFI partitioning det par displays attributes.
For MBR partitioning det par does not display attributes.
What should be checked in MBR?

Check the remarks in here
GPT and MBR attributes behave differently on volumes

And one final thing:

I will not mark the issue as "Solved" yet, until we see if this is an intentional change the Redmond geniuses have decided, (i.e. show the Recovery partition in volume list, only if it's "Required"), or someone screwed up with the latest update.

Something I noticed, in the screenshots above which probably shows that the problem, although seems to be solved by the recommendation of @Kyhi, is most likely a screw-up from Microsoft.

In the two screenshots above, in the first one the EFI partition and in the second one both the EFI and Recovery partitions show as 100% free space, i.e. not used at all.
This is not the case for both of them as they both have data written.


So it seems that it's not just the Recovery partition not showing in the Volume list, but a more complicated issue, which needs Microsoft's attention!
