After having some issues after upgrading to Mavericks I have decided to clean install all my systems.

I needed to clean install Mavericks on my old laptop but would be too slow to use USB. Also could not be bother to connect external harddisk. The solution, create a second partion and use as setup as startup disk. Process was modified from here and here.

  1. Download Mavericks Installer
  2. Create an 8 Gb Mac OS Extended (Journaled) partition
  3. Run creatinstallermedia from installer and point to partition
    sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction
  4. Restart holding down the option key
  5. Select the disk named “Install OSX Mavericks”
  6. Select Disk Utility in OS X Utilities and erase the disk you want to onto
  7. Quit Disk Utility and select Install OS X
  8. Select the disk you just erased and install as usual

On my old MacBookPro I partitioned my internal 500 Gb HDD and installed onto my 64 GB express-card SSD.

To tidy up I just deleted the partition named “Install OS X Mavericks” and expanded the remaining partition back to the full disk space.

I also need to clean install my Retina MacBookPro so will also work out how to do this from single SSD.

One word of warning, don’t try this with an iMac with a Fusion drive. There are lots of reported issues with partitioning Fusion drives. Will explain more when I Clean install my iMac.
