It's possible that the OS installer does not even see your internal HD because it is not formatted in anything that it can recognize.
Run the installation software again and after about the second step you will see the menu bar appear at the top of the screen.
Choose Utilities (or words to that effect) and then Disk Utility.
Initialize the drive as HFS+(Journaled) with a GUID table.(It will probably default to this table)
Restart and go through the install process again. This time you should see the disk as a destination option.
Of course, the other option is that the drive is totally messed up and does not work at all.
I have a 13" macbook with an intel core/ 2.1 GHZ/120 GB hard drive/2 GB memory. I got it with OS 10.4, but then got the leopard upgrade dvd free when it was released. Recently through a series of unforeseen events I ended up with my hard drive scrubbed clean of everything (OS et. all) I figured it wouldn't be that big a deal. I can just pop in the restore dvds that I got with my mac and I'll be good to go.
Problem: I go through the installation process until I get to the step where it asks me to select what 'volume' I'd like to install everything on except that it won't give me any options. It doesn't show my hard drive. It gives me a blank and so I can't continue.
I'll confess that I don't really know all that much about troubleshooting with macs... I'm not exactly a recent convert, but since I've never really had any problems with it I haven't exactly had the chance to learn. (a little ironic, but mostly annoying)
I bet it's something really obvious....it always is.
thanks in advance
