I was just wondering if someone was sucessful in creating a triple boot of OS X, XP, and Vista without using outside programs like rEFIt or bootpicker. I tried all weekend with no avial. All the times I installed, when booting, XP or Vista said they were corrupt or missing a file, and that I needed to reinstall. I would like to install XP and Vista for some high performance computing. Most of the articles I have found are 2 years old and wonder if there is a better (easier) way. Please give me some insight and direction. Thank you.
