Somehow i managed to not be able to re-install OS X on my macbook. I went ahead and wiped my hard drive and installed Ubuntu 9.04 on my Unibody MacBook. Now, I need to triple boot (OS X, Win7, and Ubuntu) and i'm having some serious issues. I know that normally you go ahead and wipe the hard drive and install OS X then use Boot Camp to re-partition the hard drive and then install windows leaving space for your ubuntu installation. Well i can't even install OS X. It tells me that it cannot be installed on the computer.

Please help. School is starting soon and i need my OS X and Windows partitions back....

Thanks!
