iBook G4 Wont Mount New Internal HD

[NDgamer]

Hi!,
i bought a ibook G4 off of a friend and knowning it needed some repairs it needed a new Harddrive. He had a 100Gig Seagate replaced in it before me and I tried a new 60Gig when I got it.
either one of us couldnt boot either HD, we can not find the new Internal HD with the Mac. I can boot off a External HD holding down ALT. And i already tried clearing the P-ram many times. Also when i go to load a 10.3 OSX disk it loads and either gives me a red circle X or like sorta artfacts and shifts the apple screen to the side of the page. Ive spent hours trying to fix this and have no luck. do i need a 10.4 or 10.5 disk? i did add 256MB ram to it so heres the specs. I have no clue what to do. ALSO! when i boot the external under the specs it wont show the HD under disk utilty or the about my pc info...
thank you!!!!!

When you're at the Welcome screen of the installation, go to the menu and select to launch Disk Utility. From there, you're going to select to format the drive in "Mac OS Extended" format. Once it's formatted with that filesystem, you can quit out of Disk Utility and you'll be taken back to the installation. The installation should now proceed just fine and you should be able to select the hard drive to install unto.
