I am trying to upgrade myMacair book from 10.5 to Leopard 10.6. After the installation, instead of running as  a program, I was given 
choices of either transferring from anothe Mac, anothe volume,Time Machine, or Do not Transfer. Tried Do not transfer and it justs keeps
going back to rebooting, tried from another Mac with a firewall cable, nothing, also now my optical drive is not being recognized. Its as
though there is no program installed. Any help greatly appreciated
