    Windows 10 22H2 Installation Creates New Recovery Partition


    I recently upgraded Windows 10 Version 21H2 to 22H2 using an ISO file. A new Recovery Partition was added as Partition 5 as shown below. The two images are from Macrium Reflect and Windows Disk Management. The unallocated space is reserved for use by the Solid State Disk. The original Recovery Partition remains with 15.5 MB.

    Is there any easy way to remove the original Recovery Partition and allocate that space to the C: drive? I do plan to upgrade to Windows 11 sometime next year.

    Thanks for any help.

    Hi, that's a very easy thing to do with a free 3rd party partition manager for example.

    You would simply delete the first partition, move the EFI partition, and resize C:

    E.g. Minitool Partition Wizard

    However there will also be another partition, not shown by Disk Management (by design) - typically 16Mb to deal with.

    Here's mine, somewhat similar as viewed by that program- I've just never bothered to tidy it up.
    Note the 16Mb partition.

    Thanks for the help. I'll take a look at MiniTool.

    I read in another thread that the 16 MB MSR partition is not easily moved and might require a program like Macrium.

    If that is the case I may just stay with the existing partitions. I am only using a small fraction of the available disk space.

    You are correct. The MSR partition is not easily moved - but it is very easily recreated. Using MiniTool Partition Wizard, delete the recovery partition and the MSR partition. Move the EFI System partition to the far left. Apply all those changes. The recreate the MSR partition with:

    Code:
    diskpart
    select disk 0
    create partition MSR size=16
    exit
    exit
    Now you can go back into MiniTool Partition Wizard and extend the front of C: drive partition to fill the rest of the space.

    Thank you very much for the information. That process does not appear difficult at all.

    It sounds like the MSR Partition would not have data stored that would be needed. I first need to learn how to use MiniTool before attempting any changes.

    I would also back up the disk before proceeding.

    The Recovery partition use to be the first partition, now it is after the C: partition. On an upgrade, the installation shrink ed C: partition and created the actual Recovery partition. The first one (Recovery original) was left behind and it is useless.
    You already have all the partitions, including the 16G MSR.
    - As the first partition isn't used, use MiniToll to delete it.
    - Move the EFI partition (100M Fat32) and the MSR (16G RAW) to the beginning of the drive.
    - Use MiniToll to expand the C: partition to the Left till MSR
    - Use MiniToll to expand the Recovery partition to 850M

    You have 204G of unallocated space. You can use it to create a D: data partition.

    I completed the first part of this process using Diskpart and Reagentc. The extra and unused Recovery Partition has now been deleted.

    As a precaution, I ran reagentc /disable knowing that the partition numbers would change. I don't know if the disable command was necessary.

    I rebooted the system and ran reagentc /enable. The new Recovery Partition that was formerly Partition 5 is now Partition 4. Everything appears to be working normally.

    I have seen comments that it is safer to make certain partition changes from a boot device with Windows not running.

    As a result, I may hold off on the other changes for the time being.

    Thanks all for the help.

    You did not expand the recovery partition to 850M as I recommended. Soon or latter Windows will need more space and will create a NEW Recovery partition leaving behind the actual.
    You have a unallocated space on the beginning of the drive and at the end.

    Expanding the size of the Recovery partition looks pretty safe. I will try that tomorrow.

    The unallocated space at the end is set up by the Samsung Magician Software for use by the Solid State Disk. That space makes it easier to manage the read and write cycles, improve performance, and extend the life of the drive. I can remove that allocation temporarily to extend the partition.

    On the EFI and MSR Partitions, one option is to use Macrium Reflect which allows you to drag and drop partitions from source to destination as desired. That may be a safer approach.

    Run reagentc /disable, enlarge the Recovery partition and then reagentc /enable

    Space needed for SSD maintenance is much less than 20%. I would say that 20G is a good size but if you don't need the space, leave as it is.

    I have used Macrium Reflect to do it on mine.
