I have a system that shows the first Partition as EFI System Partition

Is it possible to create and restore images of this system with IFL or IFW (3.43)?

I have spent hours trying without success.

I tried IFU, but I can't figure out how to mount a drive to save or restore the image (USB or Network).

I tried to install BIU 1.22, but it appears to install, but gives Missing Operating System when restarting.

For anyone else's information, yes, IFL/IFW can save and restore Windows 10 with EFI System Partition.
The issue was BIOS setting for RAID was different between the two systems.

timg11,

Do you have BIU installed now? Or still having a problem?

No, I have set aside the dual-boot for the meantime. I have been able to get Windows working and that will meet my immediate requirements.
Eventually I will get back to dual boot and try to install BIU again.
Now that I know the RAID setting was the issue with Windows, it seems likely that it was also the issue with BIU not installing.
I found an article to convert Windows from RAID to AHCI, which I will attempt, followed by installing BIU and then attempting dual boot to Ubuntu.

I gather you have an image of the Ubuntu system. Is that an Entire drive image? If so it contains an image of the ESP which contains the Ubuntu folder. Having this folder should make setting up the dual boot much easier. But having the folder isn't essential. One can be created.
