I have to reformat my MBP in order to partition my Disc for boot camp (Pic 1). the apple store said for me to do a erase and install of leopard, run the boot camp assistant and install windows. after that, use migration assistant to bring everything from my time machine backup to my computer. one question i have is if its going to migrate EVERYTHING back. like all my apps. or do i have to reinstall all of them. i'm asking this because in the assistant it says its going to migrate back 7.3 GB of my apps when i rally have 12.05 GB when i click on get info of my applications folder (Pic 2) . and right now i have used 75.34 GB of my hard drive but the assistant says its only going to migrate 56.6 GB. what happened to 20 GB? PLEASE HELP!
