14.04LTS installation problem

[Bashing-om]

That to me looks as if all we are looking at now is installing grub onto the EFI partition (sda1) .
As the disk is formatted 'GPT' will require that grub be installed there.

Unfortunately, I am not familiar with 'GPT' and do not know off the top of my head how to check/install grub to the EFI partition.
If between now and then, oldfred - or another, does not advise, I will find out.

and we will carry on

Some old BIOS do not correctly see new multi-TB gpt partitioned drives.

Also with really large drives much better to have a smaller system partition (/ root) of 25GB or so and then partition rest of drive as /home or data partitions.

You show a bios_grub partition. That is for BIOS boot not UEFI boot. If an old system, you will not have UEFI boot. The bios_grub only needs to be 1 or 2MB but must be unformatted.

would it be plausible to take the old 120 GB HDD and use that as a master and have the OS boot from there, and have the 3 TB as a slave drive and cut my losses on the 2nd 3 TB drive?

[oldfred]

Does BIOS see 3TB drives correctly? If so you should be able to use them. But keep a smaller / partition at beginning of the drive.
If not they may not work as data drives either.

I have been looking around about the problem and from what I can understand, It has something to do with the start sector not starting on a track that is not a multiple of 8. and how would I make the / partition smaller?

If you use gparted or gdisk to create partitions it will do it correctly.

sudo apt-get install gdisk

First, understand that most partitioning tools have moved to a policy of aligning partitions on 1 MiB (2048-sector) boundaries as a way of improving performance with some types of arrays and some types of new hard disks (those with 4096-byte physical sectors). See article by srs5694:
