You must use the 64 bit Win 7
But there is no support for UEFI on the Win7 install disk ...
so here is what you do.
This also works for old installs, that needs to be transferred.

Take a temp disk, any size, and install the Win7.
You will have a MBR disk and boot, and all disk above 2T will not be accessible.
Create a modest size Windows partition, to make things easy further on.
How about 60G ?

OK. Your old Windows-64 is now on some disk, and we shall transfer to a new disk, like 4T size.
Start by removing disk cables to absolutely everything....as a precaution.
Now attach the new empty disk. This will be erased.

Start on a Win7 recovery disk, and go to the recovery console.
Or start on the install disk, select keyboard, and press
Microsoft-secret Shift-F10 to open a console.

Start Diskpart, and erase all data and partitions on disk.
Please kindly select the right disk !!!

DISKPART
LIST DISK
SELECT DISK 0
DETAIL DISK

Please kindly select the right disk !!!
Delete partitions:
LIST PART
SELECT PART 0
DELETE PART

LIST PART
CLEAN
CONVERT GPT


Now you have an empty disk.
We now create the boot partitions, but do not fill with any data:

UEFI Boot:
create partition EFI size=100 offset=1
format quick fs=fat32 label="System"
assign letter=S

LIST PART

Nice!
Next!

create partition msr size=128 offset=103424 
LIST PART

You now power down, and connect cables.
copy your Windows partition onto free space on your new disk.
Do not copy the small Windows boot partition.
Your copy software will create a new partition (like 60G)
on the new drive.

I do this using AOMEI Backupper.
There are many kinds of software and utilities, that can do this.
But we have no UEFI boot.

Note that Microsoft install disks self-detect if the install DVD
was booted on UEFI or not, keep this info secret, as usual, and then
install an MBR or UEFI boot. So you must struggle with making your
DVD drive boot in UEFI mode...

OK.
To install UEFI boot you need an Windows disk that support UEFI boot.
Your Windows 7 disk is unusable.

So, I took an Windows 10 install disk instead.
Start the disk, and (um, preferably, umm ) press Sift-F10 just after
you selected your keyboard layout.

You now have a console window, that support UEFI.

DISKPART
LIST DISK
SELECT DISK 0
DETAIL DISK
LIST PART


... so we are on the right disk ...

Arrange the correct drive letters:
SELECT PART 1
ASSIGN LETTER=S
SELECT PART 3
ASSIGN LETTER=C

LIST VOL
EXIT


If you have your windows elsewhere, change the C letter.

Now the magic:
bcdboot c:\windows /s s: /f UEFI


Reboot, change boot in BIOS to UEFI.
Remove all cables except to the new disk, and reboot.

You can now easy change the size of the C: Windos partition,
add more partitions, copy over data to your now disk.

To copy disk including user/security settings, use the ROBOCOPY
utility using the /MIR switch.

ROBOCOPY D:\ F:\ /E /DCOPY:T /XO /W:20 /A-:SH /XJ /R:1  /XD $RECYCLE.BIN /ETA  /XD "System Volume Information" /MIR
