The new "reinitialized" wallet isn't going to help because it has an entirely different HDseed that will generate entirely different set of keys.
What you need is a backup of the old wallet.dat that you've used to receive the bitcoins.

The only solution I can tell is to use a "file recovery software" to try to restore the old deleted wallet.dat. And hopefully it's still useable.
The main factor that lowers the chance of recovery is if you've been using the drive since it was deleted.

For the file recovery software: you'll have to find a reputable one, the procedures are different per software;
and I'm afraid I can't help you with that (use the software's tutorial if it has one).
By the way, is your Bitcoin core fully synced?
What do you mean by "reset your wallet", because I don't see any option to reset a wallet aside from manually deleting it from the data directory.

You can't... if you don't have a copy of the original wallet.dat, your chances of retrieving your coins are zero.

Do you have any sort of backup of the original wallet.dat? If not, then as nc50lc says, you'll need to try some sort of file recovery software to see if you can recover a previous version of the wallet file.

I don't think OP would make a conscious decision to navigate the filesystem and delete their wallet.dat (1 BTC was worth more than $350 back then so you can imagine how valuable 75BTC would be, not to mention the datadir is in a hidden folder by default.

Maybe OP just created a new wallet from the File > New Wallet command and the recent wallets history was cleared somehow. The "lost" wallet should still be in the folder. Follow the instructions at https://bitcointalk.org/index.php?topic=5308461.0#post_WalletLocation for your OS to find the location of Bitcoin Core's files and then verify if you see your wallet there (it could simply be called "default/wallet.dat")

This is not clear I would like to know if how did you reset is it the PC or the Bitcoin core wallet?

Actually, there is no reset button on the Bitcoin core wallet so I guess it was your PC?

If it was your PC then it won't be easy to recover the wallet you might need to use some 3rd party software like Easus file recovery.

Can you try to install everything and use that thing to search on "wallet.dat" let's see if it can find two wallet.dat on different folder.

You don't want to install anything on that drive.
You don't even want to boot up that machine anymore.
Every time you boot up that machine and or install software on it you risk overwriting your old wallet.dat and that will definitely send your coins down the black hole without the possibility of recovery.
I just can't understand why people give the advice to install stuff like recovery software onto that drive it's the worst possible advice you can give someone that is trying to recover their lost funds.
We have seen cases where the user installed easus recovery on top of his old wallet.dat and the act of installing the recovery software overwrite the old wallet data which made it impossible to recover the funds.

A better way to recover your funds is to boot up that machine from a dvd or usb stick and mount the drive read only so that you can be sure that the data is preserved.
Then you can run a recovery software to look for the file.
The problem is usually that the USB stick will be too small to save all the files that the utility finds.
So a better solution is to remove the drive and hook it up to another computer that has enough disk space to save the recovered files.
Also windows is not your friend for this task.
Linux is free and has the best recovery tools available, which are also free so don't think about spending one buck on recovery software because it's no needed at all.
