Moving or recreating EFI partiton
After a recent upgrade to Win10 from Win8.1 I decided to add an new SSD as the primary disk and reinstall a fresh copy of Win10 to it.
I installed the new SSD and kept the old one in there as well. After the installation was complete and I was satisfied that I had everything from my OLD SSD I decided it was time to remove it. Now I have discovered that my PC is booting using the EFI partition on my old SSD and the new Win10 install did not create one on my new SSD. So I've had to keep the old SSD in there in order to boot.
How can I non-destructively create an EFI partition on my new SSD so I can remove the old one?

What partition did it create then during new install? only C:?
In any case - if you decide to install Windows 10 from scratch then it is a good idea. But before you do this - disconnect the old SSD or change at least their priority in BIOS.
Manually creating partitions will bring you only headaches.

Hi All,
Thank-you everyone for your comments. I think I'll erase and reinstall fresh with the old SSD disconnected.
As a matter of interest I had moved the original SSD to a different SATA connection (slower, as I wanted the new SSD on the fastest) and changed the Boot Order in BIOS before booting from the USB stick with the installer on it.
I thought the new install would create all of the necessary partitions on the new SSD but it didn't.
Cheers,
Erik
