A few years ago I bought a Samsung Series 9 laptop with Windows 8. Then I updated to 8.1. Now, when my SSD have a few free space I check my SSD partitions. I get:

DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Recovery           500 MB  1024 KB
  Partition 2    System             300 MB   501 MB
  Partition 3    Reserved           128 MB   801 MB
  Partition 4    Primary            215 GB   929 MB
  Partition 5    Recovery           349 MB   216 GB
  Partition 6    Recovery            20 GB   216 GB
  Partition 7    Recovery          1024 MB   237 GB

using diskpart I discover that partition 1 is for Windows RE, partition 6 and 7 are labeled as SAMSUNG_REC. partition 6 has a filesystem NTFS while partition 7 is FAT32.

Partition 5 do not show label, it is NTFS.  I checked the web and found that it is another Windows RE. Is this correct?

It is safe to delete this partition so I could expand C: ? Why do I end up with 2 Windows RE?

Partitions 6 and 7 are the Windows image for recover, correct? if not, what are they?

If I have made a System Image on a USB HDD, It is safe to delete those partition so I could expand C: ?

Regards,

Partitions 6 and 7 are the Windows image (SAMSUNG_REC.) . I think you make a complete backup and proceed ac

If your disk type is GPT with Windows 8, when you update to Windows 8.1 it creates a new recovery partition. This does not occur on MBR disks.

Windows 8.1 currently makes it so you cannot use the original recovery partition that the OEM placed for you to recovery the original Windows 8, presuming it is stock MS winre. If you were to run recovery now it will complain about not being able to find a recovery image and to insert the 8.1 DVD which you do not have. Third party recovery implementations may not have this problem, but make sure you create or have the Windows 8 recovery DVD made or acquired before removing the recovery image partition.

first ,you should understand, everything have risk,so before you delete partition to expand C drive ,you should first backup some important data, files and system image. as i know,the system drive that includes the running OS can not be deleted by Disk Management or other third party software. In this case, the only solution is to start another OS that you want to save to delete the one. If you just have one OS, and you want to delete it. You can mount the computer to another one to complete the operation. more detail you can follow this : http://www.disk-partition.com/delete-partition/cannot-delete-partition-windows7.html

Hi,

For the factory recovery partition, once you delete it, you will fail to do the factory restore. 

But you can create a system image to help to recovery your system:
