That's really an unfortunate thing that had happened to you.
I think the best possible solution is that you recover the deleted .DAT file using UNDELETE kind of utilities.
Other than that, I don't think there are any other viable options that you can do.

RawDog is a troll.

This is not true!

The link he's posting is a joke.

This is not true!

You cannot retrieve your private keys from that site.

This is not true!

Danny Hamilton is a lying asshole. 
I am not a troll.  I might have unconventional ways of pointing to interesting topics, but not a troll.

That site is not a joke.  It is an interesting experiment that teaches people what exactly keys are.  Every key on that site is a real key.  The site is not a joke, it is just an interesting directory of keys that demonstrates the impossibly large number of them.

While admittedly a bit difficult, you in fact COULD retrieve your private key from that site. 

Danny you are plain full of lies.

Yes, it is.

Danny Hamilton is a lying asshole.

And you've even gone so far as to prove my point.

That site is not a joke.

Yes. It is.

It is an interesting experiment that teaches people what exactly keys are.  Every key on that site is a real key.

In the same way that every integer between 1 and 115792089237316195423570985008687907852837564279074904382605163141518161494336 "is a real key".

The site is not a joke

You seem to be repeating yourself.

While admittedly a bit difficult, you in fact COULD retrieve your private key from that site.

Not "difficult".  Impossible.  You claim he "could" retrieve his private key from that site, while you know that it is impossible.  Again, you prove my point.

Danny you are plain full of lies. 

One of us is.

I'll let our posting history speak for itself.  It's publicly available for anyone that wants to look at what you have posted in the past, and what I have.

I guess my question at this point is: Having the private key where I sent that 1 Bitcoin can I create somehow , using that private key, another transaction where I send that 1 Bitcoin to my new wallet.dat file?
 

Do you mean 1LBKQuK7d1GA6noiudxZcBnxxL4Pxxxxxx ? That is the public key, not the private key.
If you have the private key you can do anything.
Hiding the last part of the key in xxxxxx does not matter, it can be found anyway. All transactions are visible.

Jannn thanks for the clarification. I do have the public key(1LBKQuK7d1GA6noiudxZcBnxxL4Pxxxxxx) but not the private key since it got lost when I deleted the entire initial blockchain and had to reinstall a second time Bitcoin Core. So, based on the info I currently still have which is this:
Sent 1 BTC to 1LBKQuK7d1GA6noiudxZcBnxxL4Pxxxxxx on June 15, 2016.
Status Complete
Sent June 15, 2016 at 4:22 PM
Amount 1 BTC
Sender Dxxxxx Txxxxx
Recipient 1LBKQuK7d1GA6noiudxZcBnxxL4Pxxxxxx
Reference ID b5e9bb7c-ebfc-4d51-9639-xxxxxxxxxxxx 

it is my conclusion that my 1 Bitcoin is lost forever. Kind of an expensive way to get familiarized with a crypto-currency . LOL!!!
Thanks all of you for your answers!!!

PS
Since my original Bitcoin Core (80GB) (which had the initial wallet.dat file) was installed on an external WD drive before I manually deleted it entirely, can I try to recover, somehow, that original Bitcoin Core File (around 80Gb)? That will be the only way to get the initial wallet.dat file which has my 1 Bitcoin and the private key for that particular 1 Bitcoin transaction.

Tks!

The 80GB are the blockchain. All you need is the small wallet.dat file. If you deleted it, then IMMEDIATELY STOP USING THE DISK FOR ALL OTHER PURPOSES and attempt to use an undeletion utility. Your mileage may vary; in retrospect you should have had a backup of this file.

Recover wallet.dat, you do not need the rest.
If you find it you have your 1 Bitcoin back. If it got overwritten on the disk it is gone forever. Whatever you do, stop writing to that disk until you recovered files.
