I am using UEFI, and GRUB for my bootloader. I did update my post with a bit more information now.
I was not able to select boot order in BIOS because it wasn’t reporting properly, or my drives were “messed up” along the way.
I did not have the option for my Windows drive listed as a bootable option. It did however show a generic entry for my WD Black drive (which is what I installed Arch on) as a bootable entry, but it ended up booting to windows after forcing the machine down because Arch hung at initializing Ramdisk.
I had the afterthought to choose to install os-prober for grub within additional packages.
