[SOLVED] Cloned OS to m.2 SSD, cannot format C Drive

[RecreationalUse]

Hello there, first time posting after lurking here for some time whenever I find myself stuck.
I recently bought an Adata XPG SX8200 Pro (1TB) to move my windows 10 home install to from my barracuda 2tb, as well as some other information. I only had only used 400gb on the barracuda so i figured it wouldn't be too difficult to clone my C: drive and then wipe it clean after moving the OS and other information over to the m.2 drive.

I used EaseUs ToDo backup to clone it and had no issues booting from my SSD. I had even unplugged my other drives and booted solely from the SSD and didn't see any concerns. My issue is when I attempt to re-format my C: drive, I get "you cannot format this volume, it contains the version of Windows that you are using. Formatting this drive could cause your computer to stop working"

I'm unsure how I could go about cleaning out my C: drive to maximize space, or if I should be trying something else out to correct it. I also have some applications it seems still within the C: drive through ProgramData > Microsoft > Windows > Start Menu > Programs.

Any help would be greatly appreciated.

C: drive is one, from which windows is loaded.
if you have booted from new one, your old drive should have a different drive letter.

Can you show screenshot from Disk Management?

Here you go. SSD drive is labelled D:

You need to change your boot order in bios, and remove the barracuda completely from the boot menu.

It would seem when your old drive is connected its taking boot priority over the nvme drive and booting that windows installation instead.

Boot order in BIOS is changed, I got the D: Drive as the first boot with the secondary boot option disabled, But I will doublecheck it.

Boot options at the moment are Windows Boot Manager (m.2_2: adata SX8200PNP) With the secondary boot option disabled.

You got it wrong.

SSD 1TB is labeled C: "Piece of <Mod Edit> drive".
D: - is on your old 2TB HDD.

BTW - they do not seem to be clones. C: has 44GB of data and D: has 293GB of data.
