your 2011 macbook pro will not permit a downgrade because of the firmware your laptop is running. you are stuck with lion I'm afraid. the reason for this is due to lion installing a new locked firmware which protects the system. it's no longer open firmware like on a powermac, etc or earlier intel macs. I can telly you some disasters of users trying to roll back to snow leopard and it taking days to do a system recovery using the original software disks which came with the system.
