That is exactly how a UEFI-GPT should be.

What drive image software you use (Macrium Reflect)?

I used Macrium Reflect to make an image of the legacy C drive and Media Control Tool to create the USB stick. I also used AOMEI to create an image of my C legacy drive. All of that stuff is on my legacy drives.

Did someone mention my name?

I think the next step would be to make the computer boot from the EFI SSD into the new EFI Windows install, with both SSDs connected. Then set up dual booting to ensure that the legacy Windows will boot from the EFI SSD. I've already done proof of it here:
Dual booting legacy BIOS (MBR) and UEFI (GPT) - proof

I added the second Windows to each BCD with a simple bcdboot command.

I would hate to copy the legacy Windows install to the EFI SSD only to find out there is something wrong with the legacy Windows install that will keep it from booting in UEFI mode.

Have you been able to boot in UEFI mode from the EFI SSD with both SSDs installed yet? If not, I would install both SSDs and go into BIOS settings and look at the boot priority list and make sure the EFI SSD is first in the boot order. CSM should be completely disabled.

Navy - Yes I've got booting into EFI working. The bad news is that I had to disable CSM which I need in order to boot into legacy mode. I've got both drives in the PC, but at the moment I have to go into BIOS and make changes to boot into one or the other. So far I can't have both. I also cannot connect one of my SSD drives as when I do, I can no longer boot into EFI mode. I select to boot the EFI drive but the legacy drive gets booted. So it's not all good news, but hopefully we'll get there. I'm done for the night. G'night to all.

You should be able to efi boot with csm on. Check the bios settings. You might need to turn secure boot off.

Secure Boot cannot be turned off in this BIOS. It's greyed out. But I've been reading that it can be turned off by deleting all the keys. I would do that, but I don't know what effects that will have and if I need to reinstate them, can it be done easily?

Please don't do anything. I'm preparing a post with images on how to replace the C: partition.
Be patience. I need 3 hours. I'll be posting before 11:00 am

G'morning, mHz. I posted 3 apps I have used for manipulating imaging. Yes I have Macrium and have used it. Also AOMEI and MCT. I have no preference because I've never done anything like this before 3 days ago. So I'll await your instructions. Thanks for doing this.

Did you have Macrium Reflect installed?
Did you generated a Rescue Macrium Reflect drive?
