ok heres the issue, my HD crashed a few days ago so, i bought a new one and replaced it myself but theres an issue with snow leopard running now.. i can boot from the Snow Leopard disc and the Leopard disc to run Disk Utility, but it wont let me re install them! i boot from Snow Leopard and my comp tells me it wont install because it needs 10.4(Tiger), ok, tried that. Tiger CANNOT be installed on this system as of now. i re formatted my new HD to MacJournaled, and still, NADA! now im wondering if its possible to completely wipe out the remains of Snow Leopard from my logic board or where ever it continues to linger.. i want it out to re install Leopard fresh and brand new.. If anyone has any ideas i would greatly appreciate the help, ive been working on this for 5 days now!
