Evening folks. Think this one is for the more experienced users cause I can't pursued mine to do it, perhaps you've have? Here's the setup: Currently my MBP17 (alu) has two HD's installed but they're not RAIDed, the other unit is simply there are added storage. For many years I've never had the need to install Windows until now and since there's no internal optical drive I've been installing everything from the external Lacie Blu-Ray drive and it's been fine; up until now - but maybe it's because I've not tried it before? Problem: Anyway... Does anyone know would it be possible to install Windows from a external optical drive connected via Firewire? Because whenever I try, all I get a flashing icons (the usual grey apple logo then a no access mark followed by a folder with a question mark in a folder). What I do: 1. Start bootcamp, select Install Windows. 2. System restarts 3. Press and hold option key on boot up. 4. then select the Windows DVD After, the system shows flashing icons. a. grey apple logo b. circle with a line through it c. grey folder with a question mark. d. (repeat from a) Anyone have any suggestions? Does the optical drive need to be an Apple supplied unit?? I seriously have no idea. All I know, this drive can install windows on the MP without a glitch.
