USB installer and uefi

Hi,
 
I used to create my usb key installer using dd of the usb file generated by distro_const on an xstream machine.
Recently I received a more recent NAS appliance with a uefi only bios and I can't find a way to show the usb key and boot from it.
Technicians of the appliance told me that this new motherboards do not support legacy boot and need the usb key to be uefi.
Any idea where the problem is here?

Thanks,
Gabriele

For uefi boot, you need partitioned “disk” with EFI System Partition (ESP) on it, created FAT file system on it and loader64.efi copied to efi/boot/bootx64.efi on it. Depending on firmware, it may require FAT32, for safe side, you may want to use ~34MB ESP so you will always have FAT32 on it.

Hi, hi found the solution.
I used this tool that works great:

https://github.com/AustinWise/SimpleDiskImager/releases
 
On the system bios I had to disable secure boot, remove any hardware raid, set the controller into xhci mode.
This way I can boot the key and install correctly with a mirrored zpool.
 
Thanks!
Gabriele
