I have read many forums with the same title. Yes I'm aware it's usually hardware issues but please bear with me.
Issue: after install bios shows no bootable device. If I enter boot menu and tell the bios to manually boot my hdd it works fine. Reboot and back to no device found
1. Verified all csm and uefi settings tried changing it all per posts on the forums no affect. (Still required manual boot from bios bootmenu)
2. I have used this drive on an Ubuntu install it worked fine, installed truenas scale no automatic boot (if i, installed Ubuntu it worked. Reinstalled truenas. (Not the hdd)
3. Verified /dev/sdb2 (efi partition on boot drive) had the appropriate files present
4. Moved truenas hdd to newer computer with more uefi support settings to troubleshoot. Still required to boot from f10 bootmenu.
Conclusion:
Must be something during installation. Unlike other forums my installer doesn't give me the option to select boot environment manually (both partitions look to be present though). Installation media will not boot via legacy bios only mode. But boots automatically with uefi turned on. Once booted all works fine.
