How it didn't want to boot, did you enter the GRUB or just stuck in UEFI or something else? I'd guess you stuck at UEFI stage and can't enter GRUB.

If it makes any difference, I can't recall if I plugged it into the same SATA port on the motherboard. It's a board with 6 sockets,
For most motherboards, this will not affect if you have removed the old disk, UEFI will search for available EFI partitions.
But you need to recreate boot entries via efibootmgr or grub2- install.
I was hoping that when I used dd on the whole drive, that doing so would have created everything it needed on the drive.
Or is this a case of UEFI needing to be set for the right SATA port?
