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.

Not sure why you used AOMEI if you were already using Reflect for backups and I told you how to deal with this using Reflect, but to set the Recovery partition up correctly again, go to diskpart, select disk 0, then the Recovery partition and enter these commands:
set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
gpt attributes=0x8000000000000001
Then open an elevated Command Prompt and type “reagentc /info” and make sure Windows RE still shows as enabled and points to the correct partition number.

hello jphughan - MY BAD.
Please clarify - Are you saying that I need to open two command windows with the elevated permission?
On one command windows, I will enter diskpart commands and on the other command windows, I will enter reagentc /info. Is this correct?
Thanks.

jphughan,
Do I really need a recovery partition? Because you have posted your comments below. Essentially, Windows will create a new RECOVERY partition when it needs. THANKS.
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.

Windows will create a new one automatically only when you upgrade to a new Windows 10 release, not automatically whenever it’s missing. The Recovery partition allows things like Automatic Startup Repair and BitLocker. It’s not absolutely necessary if you don’t care about either of those things, but it’s worth fixing anyway because if you just leave it there, you’ll get the new one between your C drive and current Recovery partition later, which means the one you have now will be dead weight at the end of your disk, and if you try to reclaim that the same way you just did, you might end up breaking the new one the same way you broke this one. I guess you could try deleting the current one entirely and just waiting for a Windows upgrade to make a new one, but then you wouldn’t be able to recreate it manually until then. When Windows creates a Recovery partition, it MOVES a WinRE.wim file from the C drive over there. If you disable WinRE, Windows moves that file back to C so that it can be re-enabled later (and potentially on a new partition), but if you just delete the Recovery partition while WinRE is enabled, then that WIM file is gone until you get a new Win10 release or you extract it from an Install.wim file on Windows installation media.
Anyway, you would use the first Command Prompt for the diskpart commands to fix the Recovery partition, then the second for reagentc to make sure it works again after the diskpart changes. But actually, I just realized that the easier option would be to just restore your Recovery partition from any of your Reflect backups onto that incorrectly configured partition. In the Restore wizard, drag the Recovery partition in the source row onto the defunct Recovery partition in the destination row and leave everything else alone. I’m not sure why I didn’t think of that earlier. After the restore, try the reagentc command fo verify it works again.

jphughan - I have learned a lot about this UEFI/GPT-based hard drive partitions. Thanks to you and others on this post. Since I am a command line guy, I would use your command line solutions.
