Welcome to the forum, and Thank You for your service to us and your country!
Since you are a soldier, I know you can take what I'm about to tell you... the only thing you've done is over thinking things, and wasted your time, sorry to say.
Then again, you were led down a dead end path by the dang DVD driver disk, that was the start of your road to nowhere. You tried to follow directions that were completely unnecessary, and in the end caused you to ruin all your good work installing Windows.
The message you saw from the driver DVD is not a standard part of its Windows driver installation procedure. The "Driver Disk Preparer" program that was run from the DVD disk, is trying to create a "Windows pre-install driver" that is stored on a USB flash drive, but unfortunately still uses the obsolete terms "driver diskette" and "floppy disk" (which can be used with Windows XP only.) The USB flash drive is used to install this SATA driver just before the Windows installation begins. That is the main and usually only purpose of that driver. The bad news is, you don't need to install this driver.
Since you had Windows completely installed, you already had a standard Windows SATA driver installed that works with your board. You can install another one later, but that can be done from a different driver installation program on the DVD, or downloaded from your board's download page.
So all your work, particularly wiping your drive, was not necessary, unless your Windows installation was damaged. What happened was when you rebooted your PC, your DVD drive was the primary boot device, since I assume your Windows 7 installation source was a DVD disk as well, correct? Windows knows better than to boot from the installation disk again after an installation, but the ASRock driver disk does not. You opened that ASR disk in Windows to install the drivers, but on the reboot you booted from the ASRock disk, whose default action in that case is to create the driver installation USB drive, since it assumes you have no Windows installation to boot from, why else would you boot from that disk?
Which leads me to, are you familiar with a mother board's BIOS/UEFI interface? That you start by pressing the Del or F2 key when you turn on the PC? It is described in your board's manual, which I highly recommend you use, particularly for a first time PC builder. The BIOS/UEFI user interface has several screens or pages, one of them is called Boot. It has a setting that selects which devices (disk drive, DVD drive, etc) the board looks at to find something to boot from. It also allows you to select the order that the devices are checked for something to boot from.
Your DVD drive was first or higher up in the order of devices checked for something to boot from, instead of the disk drive you just installed Windows on. If that disk drive was first or before the DVD drive in the boot device order, your entire ordeal would have not happened. The board would have found your Windows installation on the disk drive, and booted into Windows. You would have never seen that message that was really from the ASRock DVD driver disk. Just giving you the facts/reality of the situation, understanding is more important than candy coating the truth IMO, and I think you would prefer things that way. I hope this makes sense to you, if not ask anything you'd like to be explained more or better.
Regardless, time to start over and forget all this. Here is what I suggest you do this time to install Windows:
Since your SSD will be the drive you install Windows on, do not connect any other disk drives to the PC when you install Windows. The DVD drive must be connected if you are using a Windows installation disk, that is fine, but your HDD should not be connected when you install Windows. Actually, all you need to do is remove the SATA power cable from the HDD so it won't be on. I'll skip the details about why this is better, but not really required, for now. Trust me, it is the best way to do the Windows installation.
I don't understand how your drives were set to "Dynamic mode", was that in Windows? That is unnecessary, if it is what I think it is.
Your SSD needs to have nothing on it from your earlier installation. I don't know how you "wiped" your drives as you mentioned, but it is not good to do some of the HDD-style "wipes" on a SSD. Explain that to me please. You can start fresh with your SSD during the Windows installation by clicking on New on the screen where you choose the drive for Windows, which allows you to format the SSD.
Install Windows as you did previously, and then use the driver DVD to install the drivers. But you need to stop the driver disk from booting when you restart the PC, like it did last time. You do that by starting the BIOS user interface when the PC restarts, and setting your SSD as the first/primary boot device. Or when the PC is just beginning to restart, eject the driver disk from the DVD drive. It won't hurt anything if you do that.
You do not need to install the driver on the USB flash drive, per the instructions you found. Forget about that. That might be required only if you have your SATA mode set to RAID. If you don't know what RAID is, then you definitely do not need that driver, I promise you. If you were missing a basic SATA driver, your first Windows installation would not have worked, but it did, right?
