I've got an late 2009 macbook pro 13' and yesterday I replaced the native hd (new hd: Hitachi; same form factor).
I choosed "Restore from Time Machine" in the options menu on the snow leopard install discs and waited several hours to complete.
After an reboot the mac shows up a white screen with apple logo and tiny loading animation. Nothing happens. After another restart; the same.
Now I cant boot from CD using the
C-Key and I have no idea how to fix that problem.
