Windows 11: WinRE update with error message because partition is too small – instructions from Microsoft [Update]

[Original 8.09.23]: Since June 2023, the recovery partition (WinRE) is updated via the monthly cumulative update for Windows 11 22H2 and later. Manual installation of updates is no longer necessary here. However, problems and error messages can occur if the recovery partition (WinRE) is too small.

The error messages during the update can be “Windows Recovery Environment servicing failed” or a message “system ErrorPhase of 2”

A look at the disk management by right-clicking on the Windows icon in the taskbar is sufficient. If Windows 11 has been reinstalled and Windows has created the partitions, then there is enough space available. Previously, only 100 MB was allocated for this partition. And today this space is too small for the update to be unpacked and updated. So if you only ever update from one version to the next, you may well not have enough space. According to Microsoft, around 500 MB is sufficient here. Of course, more is better.

So if you have more than 400-500 MB for this partition (better 700-1000) you can sit back and relax. For the others, Microsoft has provided instructions on how to enlarge them using Windows means.

[Update 10.09.2023]: DK2000 and I tried out the instructions and found that according to Microsoft’s instructions, the WinRE was created under C:Windows. So not in the partition actually intended for it.

Now DK2000 tried until the instructions actually worked. Thanks for that. I checked it again and it was fine. You can see the changes at NEW: in the instructions. The rest has been crossed out.

Now the partition will be set as a recovery partition

– Above detail part can check whether the hard drive is MBR or GPT. For example, if “Type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7” is displayed there, the hard drive is in GPT.
– MBR needs the command set id=27
– GPT needs the command set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
– And gpt attributes=0x8000000000000001

Now you can check whether the WinRE partition was created list vol. Diskpart can then be used exit be terminated. With reagentc /enable enable WinRE again. Now again reagentc /info Run to check if the WinRE is enabled.

As already said above, only a few are likely to be affected. When reinstalling, it is always better to delete all partitions on the Windows disk and then let Windows do its own thing. We have described this in detail here in the tutorial.
