if data is that important, i would suggest you to seek professional assistance.
this could be very complicated if it is recoverable.

TIP.
stop using this hdd, do not power up or start windows, do not install any software on it.

are you from Pakistan or India?

I suppose the data loss is logical, I mean you have overwritten some folders and partition info, while the HDD itself is OK?

If so, then you can scan the drive, searching for files and folders, which weren't affected by OS install. Proven data recovery software with NTFS support will do. Start with Raise Data Recovery, it's quite easy to use and powerful to find the remaining data at the same time.

Be sure to stop using the source drive completely and save recovered data onto another hard drive.

When have you lost the files? Do not use your computer until the data recover, overwritten will cause permanent data loss.
200Gb data loss, I guess you may need to pay for the recover.
