How can I ensure that hard disk is first, at every boot?
You cannot. The kernel will enumerate the devices in the order it becomes aware of them, which is not deterministic. To get reliable device names you should use /dev/disk/by-*/* which are guaranteed to be stable between boots. Alternatively, as Reindl suggests, both the kernel commandline and fstab (and probably others) support specifying devices by UUID=, LABEL=, PARTUUID= or PARTLABEL=, which correspond to the /dev/disk/by-* entries.
