There has to be a reason why you can't and the installer is telling you. You're just not telling us.
Not enough room, damaged, it's the install CD, it's not the internal HD,
Gotta be something.
Do it again and read the error mess completely.
How many choices of drive do yo get
I`m trying to install panther on an 500 mgz imac, everything goes good until I get to the section where i got to choose where to install, my hard drive appears but it got a little red warning that says that I cannot install mac os or start my machine on that hard drive, any help? do I need a diferent hard drive? thanks.
