    I recently bought a new rMBP and wanted to do a clean install with an external hard disk I have previously used to install Mavericks onto my old Macbook unibody.

    However, when I press the option key and select the disk on which I extracted the installer, I get to see a grey screen with a stop sign. What is this supposed to mean?

    You can't install on a new Mac that came with Mavericks installed the Mavericks you downloaded from the App Store : this is not the same "Build".

    To do a clean install of Mavericks on the new MBP, use a Cmd + r boot, or option key boot and boot up from the Recovery HD.

    Thanks Bruno, I didn't do that, but used the internet recovery option instead, which worked out fine.
