FreeBSD help requested!

Long story short: I have an important system failing to boot, and I've already broke something, and I would really appreciate someone giving some suggestions before I break it even further.

So I have a home server running FreeBSD, with a zfs-root SSD and a separate zfs volume with some spinning disks keeping all the data.

All of a sudden, the machine went down and failed to reboot. I connected a monitor to it and it was stuck with an error saying it was unable to boot an operating system, pressing a key got me to the "OK" prompt, and waiting for a reboot got me into the bios config.

It's been a while (and one upgrade to FreeBSD 14) since I installed it, and booting from the FreeBSD installer and using gpart to check the partitions shows that I have both an EFI and a freebsd-boot partition on there.

I tried to reinstall the bootcode using:

gpart bootcode -p /boot/boot1.efi -i1 nda0<br></br>

But this did not change anything.

Then I thought that perhaps I was using BIOS and used that instead:

 gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 nda0<br></br>

Well,.that was a bad idea. Now nothing boots, and the drive doesn't even show up in the bios settings screen as a bootable drive anymore.

At this point I realise I'm flailing aimlessly and probably shouldn't touch the drive anymore.

I'm pretty sure the zfs root is still there, as I can see it if I do zfs import, but I haven't tried importing it after booting from the USB drive.
