[QUOTE="chas_m, post: 1024630"] This is the key sentence. You almost certainly interrupted the machine during a firmware or system software update (which can sometimes take a while), thus damaging the directory. If you were my client, I'd be on my way to your house with a copy of Disk Warrior, which would likely repair things at least to a point where you could boot. Failing that, however, I'd suggest you try hooking the computer up to another Mac via Firewire so you can do a backup via Target Disk Mode, then take it to a tech. [/QUOTE]
