Failure to install lion. Hard drive irreparably damaged
Have 10.6.8, 4 gigs ram. Dl'd and ran Lion install rebooted to message that hard drive was damaged and could not be repaired. Now cannot reboot my machine without that message. Put my original snow leopard in drive but can't get anywhere. Also, I cannot hit the continue or any button with my trackpad.
