HELP!!!! Boot Camp and new Hard drive...

[dnance21]

Many of you will think i am an idiot for doing this....

Months ago I installed boot camp on my Mac (OS 10.4). I never went through with isntalling Windows or Linux on the dual boot option. Every time I turn on the computer I have to hold the option key down in order to choose what drive.
Yesterday, I replaced the hard drive in my computer (MBPro). I thought that I could simply hold C down when I turn the computer on and reinstall Mac OS on the new hard drive.
I cannot.

Here is what is happening to me - When I restart the computer I am getting the same blank screen, and have to hold option or "c" to boot from disk. The install is not recognizing the Hard drive as one that can receive the Mac OS install.

My question is this: How do I remove the option to dual boot on startup?
-AND- What do I need to do to the Hard Drive to have a clean/fresh install?

My other hard drive is in an enclosure and I CAN boot from it via usb.
thanks,

You have to format (erase) your new hard drive before you can install OS X.
Insert your installer disk in the drive, and restart to that disk holding the letter C.
The first screen is to choose a language, then at the next screen, open Disk Utility from the menu (probably the Utilities menu)
Click on your new hard drive to select it, then click the Erase tab.
Name your new drive, if you want to, and click the Erase button. When that completes (should only take a few seconds), then Quit that Disk Utility.
You will return to the OS X install screen. Continue with that, and you should be OK.
After installing OS X, you will be able to reinstall Windows using Boot Camp if you need to do that. If you are still using Tiger (OS X 10.4.x), that Boot Camp version has expired, so you would need to be upgraded to Leopard (OS X 10.5) to use Boot Camp.
If you have multiple boots, the option key is the quickest way to choose which OS you want at startup.
Set your default booting OS in your System Preferences/Startup Disk pref pane. You can always change that, if you prefer. If you normally want to use OS X, then set that as the default in Startup Disk. Choose a different OS by holding the option key at boot, and you already know about that. If you don't hold the Option key, then your Mac will boot to whatever you have set as a default.
