    reagntc Command Shows Wrong Win RE Partition after Windows 10 Upgrade


    I just upgraded from Windows 8.1 to Windows 10 and my system disk map looks like this:

    The reagentc / info command shows this:

    The Win RE location is partition 5 which dates from 2104 (W8.1):

    But the Windows 10 RE files are on partition 4:

    It seems the wrong partition is selected for the Windows 10 RE files. Why has the Windows 10 installation done this and how do I ensure the correct Windows 10 Win RE partition is selected?

    REAgentC Command-Line Options

    reagentc /setreimage /path F:\Recovery

    You will have to assign a drive letter to the recovery partition and use that drive letter in the command above. That resets the location of the WindowsRE file.

    If you can't assign a driver letter, The Recovery part might be a hidden partition.

    Command Prompt (Admin)
    diskpart
    sel dis 0
    lis par
    sel par 4
    det par
    det vol

    Post the output from diskpart

    You have a hidden partition > so verify partition layout..

    diskpart
    select disk 0
    list partition

    if sure win10 recovery is on disk 0 partition 4 then

    reagentc /disable
    Reagentc /setreimage /path \\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE
    reagentc /enable

    reagentc /info

    Yeah, I forgot about the MSR and asked only for det(ails) on par(tiition) 4

    Thanks for adding what Steve C needs to do after verifying the schema.

    par1: 300MB Recovery
    par2: EFI
    par3: MSR - hidden
    par4: System c:
    par5: 450 MB Recovery
    par6: 450 MB Recovery

    Steve C can probably eliminate the 300MB Recovery (par1) and the last 450 MB Recovery partitions (par6)
    They're only 750 MB in total - so you can leave them with no harm.

    Any thoughts Kyhi?

    Don't take any action Steve - there's not enough information about the partitions yet.

    Windows 3.1 to Windows 10

    or he can copy winre.wim from partition win10 re to partition 1
    and delete the last 2 partitions and gain the space back into c

    as PC appears to have been upgraded twice to win10 - thus the 2 extra partitions...

    Thanks to Kyhi & Slartybart for spotting I was counting partitions based on Disk Management and missed the hidden partition. The original installation was Windows 8 Pro then upgraded to Windows 8.1 Pro and to Windows 10 Pro yesterday. The full partition layouts from Diskpart and Partition Wizard are shown below:

    It looks like Windows 10 is using the right recovery partition - Partition 5 according to reagentc /info.

    Was Partition 1 which now has no Win RE files the original Windows 8 recovery partition?
    The idea of moving Win RE files to the first partition is attractive but I don't seem to have enough space since I only have 162Mb free. How would I do this without trashing my PC?

    An easier fix would be to delete partition 6 (from Windows 8,1?), move Partition 5 to the end of the disk then expand current Partition 4 [Drive C] to use the empty space.

    Seems like a lot of work to reclaim 450 MB of disk space at the end of the drive.

    I would relabel part 1 to Kaspersky Rescue, just to avoid any ambiguity
    Then delete part 6, leaving the 450 MB unallocated

    Who knows what the next Windows drop (Redstone 1 - 29 July 2016) is going to do? It might change the disk schema once again !

    Good point - I'll decide what to do after 29 July. Wasn't partition 1 created by Windows 8 and Kaspersky Anti-Virus has added more files to that partition?

    @Kyhi
    This won't work since partition 1 is 300MB and the WinRe.wim in partition 6 alone is 335.45MB.

    @steve C
    FYI, Each time you upgrade or perform in place repair, another 450MB Recovery will be created. The WinRE.wim for Win8.1 is removed from the 300MB partition and replaced by a new WinRE.wim for Win10 in the new 450MB partition.

    For Win 8.1 the GPT partition scheme is: 300MB Recovery, 100MB EFI System, 128MB MSR and C drive.
    For Win10, the GPT partition scheme is: 450MB Recovery, 100MB EFI System, 16MB MSR and C drive.

    If you wish, you can re-align the partition scheme as shown in this post:
