the machine's owner said she had lost the install DVD. So this is what i did:
-I downloaded a tiger OS X install dvd image through torrent
-I replaced the old hard disk for a new blank hard disk
-I've been trying to load the OS from CD/DVD drive pressing C at startup so it can install on the new HDD, but nothing happens. It starts to seek the OS in the drive but after a while it stops and the question mark appears.
I have tried with .dmg and .toast image files, should i try with .iso format?
I also downloaded a 7.5-GB leopard OS install dvd image, but its too big to fit on a regular blank DVD. Could i install it through USB?
Like I said before, i'm new in Mac and i would appreciate alot your help
