Often, these errors go unnoticed until the problem becomes visible: your Mac might refuse to boot, crash unexpected, or worse, critical data might disappear from the Finder.

Install Mac OS X 10.5 Leopard With An External Hard Drive. Ok so this helped a lot, I was trying to install snow leopard on a 2006 macbook pro 15.4 because my mac hd had failed and would not boot, so I had to format and re-install, lost the original disc. got a disc 10.6.whatever that came with my brothers new 13 mac pro 2011, and of course got the cannot install on this mac message while trying to install.

Anyway like suggested I used the snow disc to get to disc utility menu, got a hold of a 10.5 leopard .iso install file, used a partition on an external hard drive and turned that into a mac cd installation drive (using your instructions) but then even though it showed up as a boot disc when choosing disk to boot and restart off of, it would not actually come up when the comp restarted.

I did try that first off: I put it into Target Disk first thing to get the data off of it - since I had no idea whether I was going to be able to get it going on its own, or whether the drive was going to die a horrible death, at that point it seemed to be the number one priority.
