Hello there,

I have installed WD Blue SN550 250GB NVMe SSD to My Dell Vostro 3480 Laptop (Intel i3 – 8th Generation,1TB HDD and 4GB RAM, Windows 11 OS -Microsoft Official Update)

Now, First of all, I made the connection properly after that, I have given a Name to my SSD (D- Drive) and then Migrated (CLONE- Whole C Drive Data such as OS Files and Softwares! After Successful completion, I set up the Boot Loader to NVME SSD (WD) and Now, My Laptop is Running from WD SSD New Drive (D- Drive) and not C- Drive but what to do the space of C- Drive? 199GB is there and “We already know that we cant format or delete C- Drive” Now, tell me how to do it? or any other relevant suggestions!

You can format your C drive safely if it is not the boot drive. (there is no such thing as you cannot delete c drive, the rule is you should NEVER FORMAT YOUR BOOT DRIVE ) which can be anything.

To delete your old hard disk partition.

Right click on your computer icon ( This PC) in windows 10-11 and click manage, then go to disk management, check and verify the hard disk for the partition you want to delete(199gb in your case). Verify that it is not marked as boot in disk management (if it is marked as boot then you are booting off hard disk and not ssd, fix it) If is is not marked as such then you can just format it and it will be fine.

(Do not format any drive you can’t see in your file explorer and you are not sure about)

If you want more help just upload a screenshot of your disk management page and we can exactly tell you what drives are safe to format.

So from you screenshot I can see that your SSD is your boot drive and the C: partition is your actual boot drive which you cannot delete.

Your D: is your old hard disk boot drive which you can delete safely and use it.

Refer to the image below.

C drive for a pc is the drive from which windows is running from at that moment so at this time your ssd drive which you initially named D is the C drive from laptop’s point of view & the original C drive in your hdd is currently D drive in laptop’s eyes because windows is not running from there & you can do anything to this D drive just like any other normal drive.

So, you mean C Drive (OLD HDD) and D Drive (New SSD) OS Files exchange and the file which I should delete is D (OLD HDD Right?)

Do not delete the C drive that is showing in your pc, that is now your new ssd boot drive.

You need to format the drive which is now showing up as D (which is your old hard disk c drive that you wanted to delete.)

Check my previous comment and refer to the image on what you can delete.

Yes, the D drive is your old C drive.
C is your system boot drive on your new ssd.

in simple terms. (what you have in you system as per your screenshots)
D: is safe to format.
C: DO NOT TOUCH

No, don’t do anything. It seems something is using D drive at the moment so until you find out what it is don’t do anything. Use task manager & resource monitor(see at bottom bar of task manager in performance tab) to see which process is accessing D drive currently.

I Did it!
Nothing happened! confused
It is working fine!

Now, the New issue is I also want to delete the DISK 1 – 747MB (Recovery Partition) and 100MB (Healthy EFI System).

But Disk MANAGEMENT is not showing any option apart from DELETE!

you can format without issues,
but if you want you can
Right-click on D
click change drive letter, then remove the drive letter.
This will disconnect your drive from windows without affecting any data.
Restart your system, check everything works fine. If all works you can just format that dive else you need to check what app is using it.

Delete them, it will show up as unallocated.
Then right-click on D drive again and it will show an option to “Extend Volume” the drive and you can add unallocated space to increase your D drive size.

Recovery partition & efi system partition are created by windows install process automatically & since you already deleted the windows drive from hdd so these partitions also lost their meaning. These partitions are not formatted(aka fat/ntfs) & that is why you only see the option to delete such partitions.

You have to rename the windows folder from your old drive to windows.old

I always prefer a clean install of windows with a new SSD. I will never clone an HDD to an SSD until it’s absolutely necessary or I don’t have time for a fresh install.

You can get rid of your old hard disk recovery and EFI partition from the windows installation menu while doing a fresh install.

If you don’t want to format and windows do not allow you to delete it then you can use any 3rd party partition utility to do so (i prefer EaseUS Partition Master)
You need the paid version (google is your friend)
or try to use an external hard disk case and format it using that.

Cool, and anyways the 2 partitions are only 800mb combined so not a big deal, you can leave it for your next format.

Also, google ‘optimizing windows 10 for SSD’ as you only have a 250GB SSD and windows does some stupid shit not good or useful for SSD.

Those EFI and Health partitions from your old drive which cannot be deleted from Disk Management tool can be deleted by below commands.

Run Command Prompt as Admin:
diskpart > list disk > select disk # > list partition > select partition # > delete partition override

“Be extra careful while typing partition numbers in commands.”

Or go with another easy but lengthy way.
Insert a windows boot USB and delete partitions by selecting Custom Installation
