EleMenTs IMAC G5 needs new OS

[HREleMenT]

HIYA ALL! I need some help with my IMAC G5. If there are any knowledgable mac users on here please read and reply. Im trying to put OS X Tiger into my G5 with a brand new HDD but when I go to load from the DVD, a flashing folder with a "?" appears and doesnt go away. If someone can give me a step by step direction on how to FORMAT, and load OS X onto the new drive it would be very helpful. I cant even boot off the original HDD b/c it crapped out on me. And apple wants a hefty price to do this for me. MAC forums dont seem to be helping either. So any help would be greatlly appreciated.

I never used a Mac, sorry, can't help- maybe someone else can.
