Question Can I recover an accidentally deleted windows 10 partition?

[AspectSaber]

Now this might sound weird and not smart on my end, but is there a way I can recover a windows 10 file on a computer? I had an old computer that did not work anymore and I don't know why. However it had a 1 to ssd in it that I decided to put in my pc for quick storage. However it had the windows 10 OS in it but I just went to disk management and deleted the partition and it seemed to work because I got a terabyte of storage. I am wondering if there is a way I can somehow recover the OS? The drive currently is being used and has only 400 GB left in it but I can delete everything in it.

You can try this :

If TRIM hasn't wiped your data, you can use the free version of DMDE to restore the partition. Normally it's just a couple of clicks and a couple of minutes.

From 1TB disk you've overwritten 600GB. There is no point even trying. Even if you recover the partition almost everything will be scrambled. If you want to boot - no chance.

1TB drive.
Then you deleted the partition
Then you put 600GB data on it

Is this correct?

No, you cannot retrieve that entire previous Windows partition. You've literally overwritten some or all of it.
In addition to the TRIM function doings its thing.
