<<SOLVED>> Program to move boot manager to use for a GPT OS 4TB HD?

[kingknightrider]

So I cloned my 2TB WD BK OS drive to a 4TB WD BK using EaseUS Partition Master 11.

And as everyone knows that puts a limit on drive total size of Windows 10 OS to 2TB.

So ... a lot of unallocated space is inaccessible -that as I understand can only be accessed in GPT format.

I tried converting the 4TB to GPT before cloning the 2TB OS -with and without partitions -converts back to MBR format (in hindsight should be a duh).

At reboot all of these tries are not detected and not seen in the BIOS -no UEFI BIOS I found out.

I read somewhere that if I could get the computer to boot off another hard drive then the GPT OS drive could boot.

 

So that brings me to the question:

Is there a program to change the Hard Drive for boot manager to use for a GPT 4TB OS Hard Drive?

Found a program to do this:

EasyBCD.

 

And following this tutorial managed to succeed in getting back full hard drive size:

Easy BCD allowed me to copy over the boot manager info to a partition I made on another disk. Though when copied something over it seems to have created an EFI partition on the main drive (the one now in GPT format) though it is missing a drive letter:
