Fluid spill kiilled my late 2009 17-in core duo 2.8 GHz. HDD survivied. Bought an early 2010 refurbished 15-in core i5 but it only has a 500GB HDD and I have a terebyte HDD with 800GB used. Can I just install the old drive in the new MacBook Pro and will it boot, or will it be missing drivers? I have a complete Time Machine backup, but I don't want to reformat the 1TB HDD as I will lose everything from my Windows Bootcamp partition the was NOT backed up. Old HDD has Snow Leopard 10.6.8 What is the cleanest way to get up and running?
