@mm2margaret I did not know how to take screenshots of BIOS thank you for teaching me that. Much better than taking them with my phone and uploading.
I am not seeing my SSD in the Boot menu. But I do see it as an attached drive. I had to format the SSD drive to APFS in order to install HS. Should I format it again to MacOS Journaled with the GUID Partition Map?

I set the CSM to Auto.

Here are the USB options:

So, Benjamin, it's clear that the only UEFI drive you have connected to your system is the Flash/Thumb drive. Your Samsung drive is not listed as UEFI which means it does not have a UEFI partition on it, which also means that it probably does not have macOS installed on it.
You have said you thought you had successfully installed macOS on that drive, but I don't think so. Sorry, but that's pretty clear. If you had, you would have seen the "UEFI Samsung..."..in the list of drives. Until you see that, with the Samsung drive with the UEFI designation in front of it, you'll probably never boot from it.
But, what is more important is the you DO NOT have a 2.5" Samsung SSD at least according to your bios. The Samsung drive in the bios says it's an M.2, which suggests its an NVMe. Didn't you say that your Samsung drive is an 2.5 Samsung SSD and is NOT an M.2 NVMe? Didn't we cover this in a previous post?
If you boot from your flash/thumb drive and you don't see the Samsung M.2 so you can successfully install macOS on that drive, I can only surmise that your flash/thumb drive is not working correctly. Because if you can boot the flash/thumb drive, you should automatically be loaded into the installer and then you should be able, using the installer's disk utility to format it and install macOS on it. Then, in the bios, it would be identified as a "UEFI Samsung..." drive.
Note that your flash drive is listed twice: once just as a flash drive, and once as UEFI flash drive. This means there is a UEFI partition on the flash drive, and it's probably because Unibeast installed something on it.
My recommendation is as follows: try once more to boot with the flash drive. The macOS installer should start. You should be able to start disk utility. In disk utility, if you see the Samsung drive, format it. The most important thing is that just seeing your Samsung drive by the installer's disk utility is all that really counts. Whichever Samsung drive is actually in your Hackintosh system.
If the installer doesn't start, that means your Flash disk is either corrupt, or faulty. If that is the case, on your "real" Mac, you're going to have to try and recreate the installer on your flash drive.
Then reboot (this step may not be necessary), and try again to install macOS on the Samsung. Hopefully, your Flash drive is actually working - if not, it's time to find another flash drive and re-create the installer on it. Unfortunately, there is a small possibility that the Samsung is faulty - but I think that's relatively unlikely.
By the way, you don't have to use Unibeast. There are command line strings that will create the installer, provided you have the "Install OS High Sierra...." app in your Applications directory on your "real" mac. The cli versions are a little more tricky, but that's the only thing I use. Unibeast is okay, I just don't care for some of it's idiosyncracies. By the way, I am assuming that you created the original flash drive macOS installer on your "real" Mac.
More details would be useful:
1. I am thoroughly confused: your bios identifies your Samsung drive as an M.2 960 Pro. This is NOT a 2.5" Samsung SSD. It's an NVMe drive. A picture you showed in a previous post was a 2.5" Samsung SSD. What is connected on your motherboard? A Samsung M.2 NVMe drive or a 2.5" Samsung SSD? Did you swap the 2.5" Samsung SSD with the M.2 Samsung NVMe? Why does your bios list a M.2 Samsung 960 Pro (a NVMe drive) if that is not is what is in your Hackintosh?
2. What version of macOS is on your "real" mac? Is it 10.13.3 or 10.13.4? Whatever version that is, that is the version you would end up installing on your Hackintosh....
3. What is your "real" Mac? Is it an older Mac Pro? An iMac? A Macbook Pro?
4. And, one more thing. You can't work with a bunch of different people giving you different troubleshooting instructions at the same time and expect a good result.
The business about USB settings and other bios settings are useless until you have good valid flash drive installer to work with, and a successful UEFI install on your Samsung drive (or another good quality hard drive). You will note that your Samsung drive is SEEN in your bios - that means whatever settings you are using, the bios sees the drive. Why it's not working is that there is no UEFI partition on the Samsung drive that contains some aspect of the macOS on it.
So think on this, and consider it, and all the best. Hope this has been helpful.
