Sorry for not being able to respond in Chinese. I don't think the optical disk will be recognised as invalid if you do not load the RAID driver. Instead the installer will not be able to recognise your HP logical drives created with the HP Storage Administrator utility. I am not 100% sure though, as I vaguely remember if you do not load the RAID driver the installer may halt at a certain stage.
The best practice in my view is to load the driver with "modprobe.blacklist=ahci inst.dd", then insert the USB stick you created with DD (typically on a separate computer and preferably with Linux), and confirm you load the driver (by entering "1 1 1 c" or something similar). If you are successful you should be able to see the HP Logical Volume(s) you created earlier (if you see nothing for your RAIDed volumes or AHCI drives instead of logical drives then the driver was not properly loaded).
If you install Linux onto a USB stick then you probably wouldn't need the driver at all.
One last note is to check your BIOS settings again before installing OS. If you altered any settings before, I'd recommend you reset your BIOS settings to make sure it is properly set to activate RAID.
