My hard drive recently died on my aluminum 15" g4 powerbook, 1.5ghz. I decided to replace it myself, it seemed like an easy enough task; simple pull and plug. The installation of the hardware was simple a 7200 rpm hitachi ata 100gb; compatible from what I read on OWC.com. I Basically need to know how to get an OS on a Brand NEW Hard Drive. My specific problem is below: When I turn on my machine, I get a small folder in the middle of the grey screen that flashes between having a "?" icon and the finder "Face" icon. I figured I need to install from the mac os x CD. I don't have the Panther CD that came w/ my comp so I borrowed the tiger CD from my sister who just got a MacBook. With the disk 1 of 2 in my computer it loads to a screen with a large power button icon and a notice to restart the machine in 4/5 different languages. Overlayed on this screen is a code script with little english but some understandable stuff saying I don't have the right driver(s), that it is "hanging in", "Panic". Can I only load Panther on it? I read something about some installers using 4 discs? Any ideas would be helpful PS: despite my profile I don't have any OS on the hard drive right now.
