So you had a drive with data on it?
And then you installed an OS on it, wiping the entire drive while you did this install?
And now you want the original data back?

1. This is unlikely to actually work. Most of it has actually been overwritten.
2. You'll need a whole other PC to maybe try this.
3. Possibly a partition recovery application. https://www.easeus.com/partition-recovery/index.htm

I wouldn't count on success, though.

dofesanket, CountMike is asking a very imortant question set:
Exactly what steps were taken just before you stopped the process? Data Recovery success also depends upon knowing exactly what was done by the install process just before you stopped the process.

See first in while booting i opened command prompt
then i wrote 'diskpart'
then i wrote "list disk"
then i wrote 'select disk 0'
then i wrote 'select partition 0' {my local disk C}
then i wrote 'clean'

I am always performing setup preparations like this.

but this time when i did like this
after giving command 'clean'
It came written 'cleaning disk 0'
'cleaning completed 100%'

after this i saw that it was written '498 of 500 gb unallocated space'
so i stopped there because i didn't want any data loss.
Help me guys!!

If only the MFT was, and not the data files themselves were, over-written -- data recovery will still be a long process but a much better chance for bits and pieces recovery. Piriform's Recuva, portable version, might be helpful here; of course, there are numerous other utilities to try. Required: an external, USB, media device to hold any/all recoverable files plugged in, ready to go.
