Running a MBP (mid 2009) 2.26GHz on OSX Leopard 10.5.8. I am trying to boot from the Startup disk (OSX Leopard 10.5.2) and when I stick it in a restart, I hold C and it hangs on the screen before where the Apple logo would appear normally, as if it's trying to load from the startup disk. The disk spins up and I hear it, but it just hangs there. Only thing I can do is a hard restart with the power button. I have started from the disk before, so I know it worked in the past. Also, OSX recognizes the disk when I'm logged in and I can even run the Installer (ask you to restart though). I recently turned on FileVault (have restarted multiple times since then) but not sure if this has anything to do with it. I am trying to set a password for the Firmware so someone can't reformat without a pw. Can anyone help? Anyone know why it doesn't want to boot from the startup disk? Thanks!
