Triple Booting an Intel Mac the Right Way
Miah Clayton writes "In the past, installing Mac OS X, Linux, and Windows on an Intel mac meant that you were forced into only having 3 usable partition slots due to the MBR/GPT hybrid limitations. Steven Noonan figured out a way to avoid dealing with the MBR partition limit and have a Linux install that isn't performance-crippled by having a swap file instead of a swap partition."
Since Windows even now only recognizes the Master Boot Record (MBR) format
This is untrue. 64bit versions of Windows support GPT, as do versions newer than Vista.
Also, I don't have a problem using a swapfile. I see no performance difference at all.
