FreeBSD 11.2 will not boot after zfs install

[DTD]

The system is an HP Pavilion 580-137c with UFI BIOS. First I tossed windows and 
did a Guided GPT install setting up partitions as I normally do. I got this 
system as a Poudriere build system. So I installed Poudriere + necessary ports 
and built a repository. All this worked fine. So as I had "little" invested in 
this system I thought I would install zfs. I used the install zfs root option 
taking all defaults. After that the system would not boot. The only difference I 
could see was bsdinstall no longer offered ACPI as an option and the console 
came up with a higher resolution (1024x768 I think). From here I tried all sorts 
of BIOS setting, secure boot on/off and some other variations. In all cases, the 
install went without error and the system would not boot giving no messages, 
just a black screen.

So I went back to the guided GPT install. Using the livecd I ran fsck on each of 
the ufs slices and then mounted them. This all worked fine but still booting 
from disk gave only a black screen. so line I tried:

    gpart set -a active /dev/ada0
    gpart set -a bootme -i 1 /dev/ada0

Currently I have:

/dev/ada0p1 looks ok: in efi/boot
    ls -l
   -rwxr-xr-x  1 root  wheel  393216 Apr 16 10:12 BOOTx64.efi*
   -rwxr-xr-x  1 root  wheel      12 Apr 16 10:12 startup.nsh*

however now booting from the disk gives the following:

    Boot Device Not Found
    Please install an operating system on your hard disk.

This is formatted as white on blue in a centered box. I assume is from the BIOS.
