Missed the Kriah Hatorah of that week

An individual who missed the Kriat Hatorah of that week ,f or whatever reason, is not required to make up that Kriah. Even if you wanted to be stringent and take a Sefer Torah and makeup by yourself, you are not allowed bec3 you need ten men. However if you do find a minyan who is reading he missed Kriah that is OK even if part of the minyan did hear the Kriah.
The Mishna Megillah 23b : One does not recite the introductory prayers and blessing [poresin] before Shema; nor does one pass before the ark to repeat say the Shemonah Esrei; nor do the Kohanim lift their hands to recite the Priestly Benediction; nor is the Torah read in public; nor does one Haftara] in the presence of fewer than ten men.
The Gemara asks: Where do we know that ten people are needed in each of these cases, derived? Rabbi Ḥiyya bar Abba said that Rabbi Yoḥanan said: It is as the verse states: “And I shall be hallowed among the children of Yisrael” (Leviticus 22:32), which indicates that any expression of sanctity may not be recited in a quorum of fewer than ten men.

The Gemara asks: From where in the verse may this be inferred? The Gemara responds that it must be understood as Rabbi Ḥiyya taught: It is inferred by means of a verbal analogy [gezera shava] between the words Toch, Toch.” Here, it is written: “And I shall be hallowed among the children of Israel,” and there, with regard to Korah’s congregation, it is written “Separate yourselves from among this congregation” (Numbers 16:21). Just as with regard to Korah the reference is to ten men, so too, the name of God is to be hallowed in a quorum of ten men.
The connotation of ten associated with the word “Toch” in the portion of Korah is, in turn, inferred by means of another verbal analogy between the word “congregation” written there and the word “congregation” written in reference to the ten spies who slandered Eretz Yisrael, as it is written there: “How long shall I bear with this evil congregation?” (Numbers 14:27). Consequently, just as there, in the case of the spies, it was a congregation of ten people, as there were twelve spies altogether, and Joshua and Caleb were not included in the evil congregation, so too, here, in the case of Korah, the reference is to a congregation of ten people. The first several items mentioned in the Mishna are expressions of sanctity, and they consequently require a quorum of ten.
The question to ask is what if one does not have ten men. Does one need ten men who haven’t heard the Kriah. Can any ten men read the Torah or do you need it to be part of minyan?
The Gemara in Megillah 5a quotes an argument between Rav and Rav Assi if wen reading the Megillah on the fourteenth needs to have minyan or not. Rav says you can read it by yourself but if it not the the fourteenth then you need a minyan. Rav Assi says you need a minyan in either case. The Rishonim are split as to who we paskin like. The reasoning is whether Megillah is comparable to Torah reading. It would seem he Machloket between Rava and Rav Assi is only by Megillah but everyone agrees that you need ten by Kriat Hatorah.
The Maharsham however brings proof from the Ramban that you do not need all ten to be obligated in the Kriah to read the Torah, and so it seems from the Biur Halacha 143:1.
The Chaye Adam though is not certain if part of the ten men already fulfilled their obligation of Kriah if they can make a minyan necessary. So rules the Aruch Hashulchan that if most of minyan heard Kriat Hatorah already then they can’t help someone else fulfill his obligation.
It would come out that the Maharsham rules that you don’t need al ten to obligated and the Chaye Adam argues. So if you can get a minyan of those like you together it would be better.
