I just upgraded my laptop and I have no additional partition (see Partition Magic disk map below). Are you sure that recovery partition wasn't already present?

Hi Steve, I didn't get one either. I think the reason is that my recovery partition is 500MB and yours is 450MB. The OP had a recovery partition of 401MB. According to System builder deployment of Windows 10 for desktop editions

• If the partition is less than 500 MB, it must have at least 50 MB of free space.
• If the partition is 500 MB or larger, it must have at least 320 MB of free space.
• If the partition is larger than 1 GB, we recommend that it should have at least 1 GB free.

As Winre is (according to your picture) 354.21MB this might explain it - there wasn't enough free space for the required 50MB free space. This is only a guess though.

Anyway reagentc /info will show the registered Winre.wim and if the new partition (probably 5 for the OP) isn't being used it could be deleted. If it is then partition 1 could be deleted - you just don't want to delete the partition with the registered RE image really

You can check which recovery partition is registered with the command reagentc /info from elevated command prompt. You'll see something like this:

Code:

Microsoft Windows [Version 10.0.14393]

C:\Windows\system32>reagentc /info
Windows Recovery Environment (Windows RE) and system reset configuration
Information:

    Windows RE status:         Enabled
    Windows RE location:       \\?\GLOBALROOT\device\harddisk0\partition1\Recovery\WindowsRE
    Boot Configuration Data (BCD) identifier: 3d8f8337-bc56-11e5-a7c5-85493d747884
    Recovery image location:
    Recovery image index:      0
    Custom image location:
    Custom image index:        0

REAGENTC.EXE: Operation Successful.


C:\Windows\system32>

To find which partition the number above you need to check diskpart as disk management doesn't show all partitions (the MSR partition specifically which is partition 3 normally). Again from elevated command prompt:

Code:

C:\Windows\system32>diskpart

Microsoft DiskPart version 10.0.14393.0

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> list par

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Recovery           500 MB    20 KB
  Partition 2    System             200 MB   500 MB
  Partition 3    Reserved            16 MB   701 MB
  Partition 4    Primary             32 GB   717 MB
  Partition 5    Primary             55 GB    33 GB
  Partition 6    Unknown             23 GB    88 GB
  Partition 7    Unknown            619 MB   112 GB

Perhaps it made a new one as 401MB is not big enough - normally it is 500MB AFAIK.

That shows the new partition is being used as your recovery partition. You should not delete it.

You could delete partition 1 and move partition 2 and 3 to the left. You can't do it with MS utilities - you'd have to use something like Partition Wizard

For 401MB I'd not bother - it is not so much space really - but if you could.

thanks a lot Ix07 for your help
in order to highlight the matter it is worth to mention the following :
when I create a backup using windows 7 included program omits partition 1 ( WINRE 401 MB ....) although Macrium Reflect and Acronis True Image don't . So, when restore from a System Image (backup) windows 7 backup program
fails , but Macrium Reflect and Acronis True Image restore successfully .

Does not surprise me - the Windows 7 tool has not been developed for years (clue is in the name). The 3rd party apps are just so superior.

Quite so - and it was only in 1511 that it was recommended WinRE came after C. Always in the past it was recommended (had to be perhaps?) before C. Not surprising Win 7 backup gets confused.
