Finally found the availability to go through this one again and for good.
Old Kingston was no good, bought a new Sandisk and no joy.
Eventually got it working with a very old usb flash drive.
"efi_load_pe: Invalid DOS Signature" was gone.
Reinstalled it but got into a new problem where ada0 was not recognized.
Boot loop where only usb would work.
Support was GREAT!
They helped me and did a remote session and they nailed it with a "setenv pfsenseboot" command.
At some point I believe we were even tricked by " being different from ' not sure to be honest, we did it a lot of times.
But we got it!
Reinstall to 25.07.1 worked well at the end.
Did a new environment and tested my restore. All good and no surprises!
Restored and rebooted and halted a couple of times to test if ada0 would kick in every time, which did ever since.
People in the forum say the support is great, I can confirm!
Thank you to those in forum.netgate and those at portal.netgate.
Thanks!
P.S. I will now try to fight again with unbound that insists to be delayed by either openvpn or pfblockerng :)
