The Tutorial:
Intro note: Here it is folks! In 10 easy (but dreadfully long) steps! Also remember, this is specifically for Macbook Pro’s that want to triple boot Mac OS 10.5+, Windows 7, and Backtrack 4 Linux.
1.
First thing you’ll want to do if you haven’t done so already would be to install rEFIt from their main web page on sourceforge: http://refit.sourceforge.net/ After its done installing you mount the image and install the application. After its done installing you might want to change its default timeout of 20 seconds and set it up to be the default boot menu. Do so by bringing up a terminal in your Mac environment and typing:
/efi/refit/enable-always.sh
Then navigate to this directory in your HD: /efi/refit/ After that then you can open “refit.conf” up in a text editor. Change ‘timeout 20′ to ‘timeout 0′ then save and close.
