Hello,

I'm trying to upgrade my MacMini 1.1 (now 2.1) to Mavericks
I created the USB disk using the latest MacPostFactor and installation went ok.

The only issue I have is when the Mac boot, it automatically start on the OS X Manager partition with the options Install over an existing one / Rehack OSX / Do a Clean Install
But not on Mavericks OS...

- I did the same with Mountain Lion : It also boot on the MacPostFactor partition.

- Last test : I replace the SSD with a brand new one : same issue on the first boot.

I suspect the Maverick partition has to be flagged as boot disk.
Is there a Terminal command ?

Thanks
