delete my partitions

I am sure this question has been addressed many time but I just want to make sure.

I have upgraded my C drive from SSD drive to NVMe drive; therefore the Image partition(volume 6) is no longer useful. 

Essentially, I just need to keep volume 0 (C drive) and volume 4 (boot partition); I can delete all other partitions, is this correct?

Side note - I am using Macrium Reflect v6.3.1849 (UEFI) software to do all my backup.

The following is my C drive's partitions:

DISKPART>
  Volume #  Ltr  Label                 Fs        Type        Size     Status     Info
  ----------  ---  -----------        -----  ----------  -------  ---------  --------
  Volume 0     C   SamSung-960  NTFS   Partition    203 GB  Healthy    Boot    
  Volume 1     M   M-PARTITION   NTFS   Partition   1126 MB  Healthy            
  Volume 2     N   N-PARTITION   NTFS   Partition     11 GB    Healthy            
  Volume 3     O   O-PARTITION   NTFS   Partition   2037 MB  Healthy            
  Volume 4          ESP                 FAT32  Partition    500 MB  Healthy    System  
  Volume 5          WINRETOOLS   NTFS   Partition    462 MB  Healthy    Hidden  
  Volume 6          Image              NTFS   Partition     11 GB   Healthy    Hidden  
  Volume 7          DELLSUPPORT  NTFS   Partition   1148 MB  Healthy    Hidden 

Thank you.

RE: delete my partitions

The image partition is not needed IF you have made a recovery image AND you have tested it.  The other partitions ARE REQUIRED to boot the system -- particularly the ESP partition.  If you delete that you will end up with an un-bootable system.

Before you do delete the image partition, be sure you make AND TEST the recovery media under Reflect.

RE: delete my partitions

hello ejn63 - thank you.  

Are you saying that I need to keep all partitions except the image partition?  Maybe I am not stated my question clearly.  I want to reduce number of partitions to TWO - ESP(volume 4) and  SamSung-960(volume 0).  Please let me know if this solution will work.

This is how I am going to test:

(1) Backup all my nine volumes to an external hard and my internal D driver(disk 1) using the Reflect's "image this disk" option.

(2) After the above backup is done, I will use Reflect to verify the image file.

(3) I will then delete all partitions except ESP and SamSung partitions using the windows 10 disk manager or diskpart software.

(4) Reboot the system, if it failed to boot, I will restore the drive with the recovery media Reflect USB jump drive.

Any comments?

Thank you once again.  

Happy holidays to all!!!

RE: delete my partitions

I would carefully read the documentation on what's required for a UEFI system before you do anything.  Some of what you're proposing to delete is required for the system to function.

You CAN remove the Dell factory image now -- everything else has a function and is needed.

RE: delete my partitions

ejn63 - thank you for the document link.  Yes, I will read the document carefully next and make sure I understand the UEFI system well before I do anything drastic.

This document is from Microsoft.  Do Dell provide another information on how they configure their partitions?  For example, do dell provide the tools to re-image my partition after I changed my hardware?

After my read, I will add my comments on this issue.

Thank you once again.

RE: delete my partitions

With one exception -- the Dell diagnostic partition -- everything else is standard issue in the drive setup.

I would strongly suggest you NOT delete the diagnostic partition -- it will be needed if under warranty you need to work with a technician before hardware repair.

RE: delete my partitions

I am not really sure exactly what you are asking.  Your title for the thread is basically how Dell suggests setting up partitions.  The answer to that is to look at the way Dell set them up.  Each partition has a specific purpose.  The Recovery partition with the WinRE Tools is for recovery options, the larger one will hold data needed to rebuild your system.  The System EFI is essential for booting.

Your initial post has a Diskpart listing showing Volumes.  It would be better for the discussion if you were to select a specific drive and they do a lis par command to get the partitions showing in the correct order.  The other way is to take a snipping tool picture of the Disk Management window and expand the columns so the descriptions can be read.  You can attach a picture using the Rich formatting option.

The OEM partitions on the drive are there for a reason.  If you do not EVER desire to take advantage of their purpose you may not need .

Just for the heck of it, open an adminstrative command prompt and type reagentc /info and include the listing.

If you wanted, you could do a bcdedit /enum all command and follow where and how the partitions are being used.  Some systems can start a diagnostic utility from within Windows.  If the partition involved with that was to be removed, you would lose that ability.

If you don't use the Dell OEM utilities then the best thing for you is to do a clean install.  Even that will put 4 partitions on the drive.  I suggest to use a new drive and kept the original one safe.

RE: delete my partitions

ejn63 - totally agree on NOT deleting the Dell diagnostic partition. My laptop is still under the warranty.

Which one is the Dell diagnostic partition? Is volume 7 with the label DELLSUPPORT?  Thank you for your suggestion.  

OK, I will only delete Image (volume 6) to reclaim its disk space but leave other partitions intact.   I will continue my reading on this subject.  I think I can eventually delete volume 1, 2 and 3 (see below).

Volume #  Ltr  Label                 Fs        Type        Size     Status     Info

 ----------  ---  -----------        -----  ----------  -------  ---------  --------

 Volume 0     C   SamSung-960  NTFS   Partition    203 GB  Healthy    Boot    

 Volume 1     M   M-PARTITION   NTFS   Partition   1126 MB  Healthy            

 Volume 2     N   N-PARTITION   NTFS   Partition     11 GB    Healthy            

 Volume 3     O   O-PARTITION   NTFS   Partition   2037 MB  Healthy            

 Volume 4          ESP                 FAT32  Partition    500 MB  Healthy    System  

 Volume 5          WINRETOOLS   NTFS   Partition    462 MB  Healthy    Hidden  

 Volume 6          Image              NTFS   Partition     11 GB   Healthy    Hidden  

 Volume 7          DELLSUPPORT  NTFS   Partition   1148 MB  Healthy    Hidden

Saltgrass - thank you.  I am going to take a break now and will circle back to this subject later.

RE: delete my partitions

You can absolutely delete the Dell diagnostic partition since the diagnostics are now stored in UEFI firmware. Maybe you’d need it if your system used Legacy boot mode, but you’re not. I’ve wiped my whole drive and I can still boot into diagnostics from the F12 boot selection menu.

On a UEFI system, you need the following partitions:

EFI (aka System or ESP, usually 100-500MB)

MSR (aka Reserved, usually 16-128MB)

Windows Recovery (usually 450MB-1GB in size)

OS

The sequence can be different than what I listed, and in fact it’s best to have the Recovery partition after the OS partition since that allows future Win10 releases to expand it as needed by shrinking your C drive a bit. If the Recovery partition is somewhere else when an expansion is needed, Windows will shrink the C drive by the amount needed to create an entirely new Recovery partition, make one there, and leave the old one sitting there as useless dead weight.

You seem to be missing an MSR partition though. That needs to exist after the EFI partition and before the OS partition and be at least 16MB in size; by default it’s immediately after the EFI partition and 16MB. Diskpart can create one using the “create partition MSR” command, but you’d have to get it created in the right place.
