On fresh system just booted from CD/CF when making manual hard disk installation using setup-disk -v the script shows the error:
/sbin/setup-disk: line 861: extlinux: not found
As result a system can not boot from hard disk.

The workaround is to install syslinux package manually before running setup-hard: apk add syslinux
