What is the error message you are getting?
Well, for fresh installation, I strongly recommend you to buy a brand new memory card first. Then, in BB installation, there should be an option asking you to make a start-up memory card, this is where the new memory card comes in.
Then... (Too long time ago... Really can't remember... T_T) There should be an option asking you to format and then install BB onto your HDD.
Anyway, tell me what the error message is so I can help more easily. ^_^
