Simplex - Heads-Up!

[Megahertz07]

I've spent all the time I can on trying to get things working.
I despaired and have given up.
I want to thank EVERYONE who has responded to my Post for help.

I have begun with a Clean Install!
In doing so, I have learned several things I had misunderstood.
Once I have finished the Clean Install, I'll try and "correctly" list what I think I've Learned.

I do appreciate your time and advice.
Best regards,

To do a clean install on a 4T drive the system must be a UEFI-GPT and not Legacy-MBR.

Reset BIOS or load defaults.
Set Disk mode to AHCI, not RAID
Select OS mode = other + UEFI (depends on BIOS).
Disable fast boot and secure boot

Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
To install as Legacy-MBR you must boot the installation drive as Legacy
To install as UEFI-GPT you must boot the installation drive as UEFI.

If you have a UEFI BIOS, you should install as UEFI-GPT
Detach any other drives (SATA or Power cable) from the MB.

During POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name) if you want to install as UEFI-GPT or select USB (name) if you want to install as Legacy-MBR.
Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.
