Hi All, Recently upgraded to Mountain Lion and decided that I would do a clean install today which I've done before under Lion (on the same machine) without any issues previously. It's a 2011 2.2 MacBook Pro with SSD. However, this time I am receiving the following error (I've also included a pic of my setup using the disk utility). Does anyone know what I'm doing wrong? The Mac is connected via Ethernet by the way as I changed my SSID before doing the install and forgot that the Mac wouldn't have any wireless until I reconnected. Rob.
