Therefore you claim to know HOW God knows there's nothing [he] doesn't know [he] doesn't know, then?
Not at all. I'm not God, I don't know what it would be like to be God, and I can't grasp the totality of how reality works. I can only make finite conjecture.
What I can do is make axiomatic presumptions and or follow yours in order to formulate logically cohesive guesswork. Which I have done.
I'm not going to go over it again when you can reread what I've posted in answer since you've yet to comment upon it with counterpoints.
I'm not making a claim; I'm examining the question HOW God can know know there's nothing [he] doesn't know [he] doesn't know.
You yourself admit a claim.

"What you have done is make a claim that omniscience is unsustainable."
In response...
"Yes, IF its supporters can't answer the question, How does God know there's nothing [he] doesn't know [he] doesn't know? Otherwise okay until some other problem may arise."
Seems in anti-theists over zealous rush to prove theists logically weak minded or just plain "nuts" they often forget or avoid admitting that they themselves often make claims which need to be justified but aren't. Why? I think its because once an anti-theist admits to making a claim they get cornered into having to defend it and often find they can't. This puts a dent in anti-theists thinking that theists fail because of their lack of absolute proof while ignoring their own. They demand an answer but upon receiving one its often ignored because of one excuse or another.
Here's an example...
Unbeliever: Why do you believe in God, there's no proof.
Believer: Why don't you, there's no proof God doesn't exist and I feel interpretively compelled internally and externally to believe.
Unbeliever: There's no evidence that God exists and I feel interpretively compelled to believe God doesn't exist.
Believer: Fair enough. One of us must be right but which one is as yet undetermined.
Unbeliever: Absolutely undetermined perhaps but there's plenty of evidence that God doesn't exist, what evidence have you that it does exist?
Believer: The evidence you speak of is interpretable, not incompatible with a God existing viewpoint, and some evidence makes it statistically more likely that some kind of super intelligent, supernatural being exists which has involved itself in creation.
Unbeliever: Hogwash, you've made an unsubstantiated claim that bares the burden of proof!
Believer: I've made a claim that is interpreted as statistically substantiated without a proven counter claim and whose counterpoints are themselves interpretive.
Unbeliever: God doesn't exist because there is no proof that it does!
Believer: Is that a claim?
Unbeliever : NO! I make no claims!
Believer: Then God might exist and I've chosen to interpret the evidence which allows for that possibility as evidence that it does.
Unbeliever: Oh shut up, you've proven nothing and apparently don't understand.
Believer: Whatever dude.
A touch of humor...
The word is Latin for 'all-knowing'. We're focusing on each of the two elements.
Yes. Indeed. But lets examine what is meant here, there are subtleties that at first glance many simply take for granted.
For instance its not possible to know what it would be like for a contradiction to actually have effective existence in reality because contradictions cannot exist in reality effectively. They are meaningless. Yet we can describe them. So does all-knowing include contradictions? Only in contradistinction between what is meaningful and what isn't. So all-knowing does not include knowledge of what cannot exist in reality simply because there's nothing existent to know.
Lets say nothing existed. Is there any meaning in non-existence which could be known? Of course not since if nothing exists, nothing would exist to be known. So when we say "all" we don't mean those things which are without meaning such as contradictions. We can't "know" meaninglessness. We can only know the terms we use to describe the boundaries between the meaningful and the meaningless.
Likewise we can't know infinity. We can only know the terms we use to describe its meaning. Its important to note at least 2 differences here though. That is, there is no known reason that infinity and all the information it may contain may not be known given infinite capacity to do so and there is no reason infinities cannot exist in reality.
WE can't know infinity simply because we are finite and haven't the capacity nor can we originate such infinities, but God as defined can.
Lets conjecture a scenario in which there is a one to one correspondence between Gods awareness(G) and the smallest unit of reality(r) which can carry meaning and since creation originates from God in this scenario reality consists of God and its Creation and nothing else. Or (G) and the set (C).
Lets further say that this one to one correspondence between (G) and all (r)'s contained within the set (C)reation is represented by an unknown number of elements (I)nformation which represents this correspondence between the knower(G)od and the known(r) within creation.
If reality consists of (G)od and the extension of Gods creative act into reality which we call (C)reation, then all knowable elements of (C) and (G) can be representationally summed by the following (a-temporal) -meaning its summation is taken to be a instantaneous process, not accumulated or summed over time - formula...
This says that if we take the smallest unit of meaningful reality (r) - multiplied by the Informational content contained within the direct correspondence between Gods awareness and (r) - summed to infinity the result is Gods omniscience.
God can know it knows everything because there is simply nothing that can exist beyond an infinite one to one informational awareness between God and meaningful reality.
Again...we establish our existence via our self awareness. Along the lines of Descartes's thinking - Our self awareness proves the case since existence is required for self awareness to question its own reality. We self evidently exist.
Similarly, we think. And because we think but don't truly "know" anything beyond what is self evidently impressed upon us we are self evidently aware of our limitations. And it is because of that awareness that the case of our limited knowledge is proven.
Likewise Gods existence is proven (in this scenario) self evidently by its self awareness.
However, unlike human beings, God doesn't "think" but Knows and knows infinitely and is consequently, self evidently aware of its own unlimited knowledge. Since this self aware infinity cannot know self limitation without contradiction such described limitation would be a contradiction and cannot effectively exist within reality. Thus God through its own unlimited knowledge of what can meaningfully exist in reality also self evidently knows that there is nothing that can have meaning that it doesn't know. IF infinity can know itself then there's your answer. Infinity leaves no rooms outside of itself for the unknown. Therefore the unknown cannot exist for a being of infinite capacity.
Now....lets be honest here. This is pure conjecture for the sake of discussion. I cannot possibly know the actual answer to your first question. I can't even be certain that your question has meaningful content since it seems to be attempting to extend beyond its own reach for an answer.
Omniscience = All-knowing
By definition one of Gods attributes is omniscience.
Then you ask how omniscience is even possible, even further than that, implying that omniscience isn't possible by posing a seemingly contradictory question concerning it.
The problem is your question is only meaningfully apt for the occasion if you can show why all meaningful things cannot be known. Easily demonstrated for finite creatures. But not so easily demonstrated for proposed beings with infinite capacities.
