To be doubly sure: * Do you have a bootable Thunderbolt, FireWire or USB drive you can plug in? If not you could create one from another system. Can you boot up from the external drive? * Or, you could boot your system in Target Mode connected to another Mac via Thunderbolt or FireWire cable. Once connected can you access the HD on your system?
