I dont think this is a must but just saying what my configuration was. I left the second partition untouched, meaning unformatted.
NOTE: I reinstalled macosx before installing Linux and recreated the partitions table with two (using apple disk utility), since I had a 1TB drive, I split it into two equal partitions and reinstalled mac on the first (512GB was used). A monitor or two so you can see whats going on :).
Installing Ubuntu/Linux Mint on Macmini is easy, but getting it to work the way you normally want a PC to run is a bit difficult (meaning, run smoothly and making all peripherals work) :) I am trying to cover all the issues I had with linux installation process and getting Apple hardware t o run happily with Linux.
