Won't boot from harddrive

I’ve been trying to install NomadBSD on a PC, which previously had FreeBSD. To be clear - I’m not trying to dualboot or anything - it’s a completely empty harddrive.

The PC boots fine on USB, the installer seems to do it’s job, but when I try to boot on the SSD, it sayes “No boot device” found - which is weird, because when I try to install FreeBSD, it works fine.

I’ve tried a lot of combinations: UFS/ZFS, Legacy/UEFI plus different partion tables: MSDOS, GPT, BSD.

Any ideas?
