I believe I've currently updated, flashed the BIOS, while using McAfee AV+.
As I understand, back in MS-Win Pro 64 bit legacy, partition management occures in 32 bit: Where's the ?????x86.efi boot file?. Does HP/InSyde offer UEFI MS-Win 7 Pro 64 bit disk management software? What Partitioning, Windows installation is required to boot into a full 64 bit UEFI managed GUID (GPT) Windows partition? I would have to learn how to write the *.efi files?
Granted minor questions for this fast of a computer; but, how may I get it right???
Thanks for any of your time,

I'm no expert and will be away for a week, but to get the discussion started, it would be good to know where you are now and what you would like to achieve?
The traditional MBR style partitioning does not use an EFI partition as the boot process is entirely different. There is a small boot loader area which only has room to load the next phase of the boot loader in a chained fashion. The traditional BIOS has no other role in the boot process.
In UEFI, however, there is basically a platform independent language that the boot code is written in and which the UEFI system executes to start the system. The whole system is built to scale and to offer protection agains tampering. A single GPT partition can handle, well, lot of data. 2 to 64th power of blocks to be exact, which with 512 block size is 9,444,732,965,739,290,427,392 bytes, about 8.5 billion 1TB disks worth to give a bit more tangible scale.
You would not normally have to write the code, the operating systems come with the tools that generate it for you and populate the EFI partition and non volatile memory so that the UEFI boot manager can start the operating system.
The support is improving all the time, so you are better off with Windows 10 for example than with Windows 7 64x SP1, which was the first Windows version with UEFI support AFAIK.
There is also backward compatibility built in so that the UEFI systems can also boot from MBR volumes, often with the help of a built in CSM (Compatibility Support Module) which emulates the necessary BIOS functions.
If you have a hard time falling asleep at night there is a lot of reading about the subject in Wikipedia to begin with:

from factory USB and see what happens.
Thank you for your time

From what I have read, it has often been a bit of rough sailing to get Windows 7 to obey during UEFI installation.
Hopefully some useful threads to get started:
