So my fiancee's macbook had harddrive failure, so I bought her a new 160 GB Hitachi HD. I popped it in, had the leopard install cd's (the 2 grey ones) and the computer boots up, goes to language select screen, I clik English, it goes to install and then says Leopard cannot be installed on this volume. OK I go into disk utility and it picks up the Hitachi just fine, I click erase and it erases. I verify disk etc. still nothing. I need help!!!!!!! And the disc won't eject. (I held down the mouse button and all.) Plz help guys Thanks!
