I am using version 0.8 and I get that error when I try to boot windows from my external hard drive on a 15" MacBook Pro core 2 duo
.............
Firmware Version:
MBP22.00A5.B01 1.12f5
I'm having the same problem on the same version of the MBP C2D. I've come so far with this and rEfit is an incredible little app, shame we are all stuck at the Legacy Boot problem... I would assume that its a matter of updating rEFit to be able to handle the MBP C2D newer firmware.... Lets cross our collective fingers and maybe one will appear
