But when I try to select the hard drive to install SL on, it has that yellow exclamation point and says 'Mac OS X cannot start up from this disk.' What did I do? What do I do to fix this? Has anybody dealt with this before? I have no other options available short of the top menu. I then selected the hard drive in the side menu and erased the disk, yadda yadda. I did the Command+R bit and selected Disk Utility. I'm running into trouble, however, when I try to return it to factory settings. failure or whatever a few years back and I'd replaced it with a 320 GB Western Digital hard drive.
