Because before it starts it relies on BIOS to provide services (in 16-bit x86 mode), but after the kernel starts, it must use its own drivers (32-bit or 64-bit, depending on your choice) and it seems it doesn't have the right drivers. Most CD/DVD drives are standard and register as ATA or SCSI drives but, as you see now, there are those that require special support.
