Can't boot from Snow Leopard DVD I bought a new hard drive for my 2011 MacBook Pro and did the following steps:


Backup using Time Machine
Replaced the hard drive
Put in a Snow Leopard DVD (10.6 from ~2009)
Booted holding down the c key


I can hear the DVD spinn for a while but I never get past the Apple logo in the boot, no error message.

Why isn't it working?
Your MacBook Pro requires a more recent version of OS X (A least 10.6.6). Mac OS X versions (builds) for computers on Support.Apple.com
