I read to use the install dvd but my CD drive is broke and wont take cds. I did manage to hook it up to my dads computer with target disk mode so i can access files. his computer is a windows though. i do have a copy of the Leopard install cd saved as a DMG on his computer and a 8gb flash to boot it but i cant format the flash drive to be mac extended journaled GUID from his computer.IS there a program to do this???I dont know what needs to be fixed or where i can get this acpi driver? can anyone help because i dont have any money to get this fix and i need my mac for college which im starting soon.This is the error message
