BIOS Boot Device

Does HDD-0 refers to the 1st hard disk detected in order from primary master, primary, slave, secondary master, secondary slave etc?

Cause I have a CDRom Drive on primary master and my linux hdd on primary slave. But I have to set the boot device to hdd-0 in order to boot from the hdd and not hdd-1.

There are two different ways to set up disk addresses loose in the wild. One way is absolute addressing like Linux uses on IDE drives. The primary master is /dev/hda, the primary slave is /dev/hdb, and so forth.

A second way is relative addressing. The first disk encountered is disk 0, the second disk is disk 1, and so forth.

It sounds to me like your BIOS is using relative disk addressing and a CD does not count as a disk drive.
