I am using a Mid-2010 MacBook pro 15 inch. I currently have 229.2 GB of free space out of 319.21 GB. I am running OSX 10.8.5 Mountain Lion. After the initial install when my computer restarts for the initial installation, after a couple of minutes my computer shows me an error. OS X can not be installed be a recovery system could not be created. Go to www.apple.com/support/no-recovery/. please restart computer. I have no clue what to do. if you do great. I have gone into recovery and reformated partition, verified disk, recovered disk....etc.
