Before we start I have a 13" Late 2008 Unibody Macbook with 2 GB of ram. Alright guys so heres my problem. I wanted to have a bigger boot camp partition so I deleted my Windows XP partition and did Boot Camp assistant again. After it completed there was no new partitioned drive on my desktop and my Macintosh hard drive was mysteriously missing 10 GB. So I was trying to find where this missing space was and in the midst of it I deleted everything on my hard drive
(yeah i'm a huge idiot i know). Now the only install disk I have is for a 15" Macbook which I figured shouldn't make a difference. When I insert this CD and try to run installer it says "Mac OS X cannot be installed on this computer". I tried to go into disk utility and wipe the drive clean but it does nothing. And in the midst of all this I am still missing 10GB of hard drive. I was able to install my copy of Windows XP but thats it. If anyone has any suggest it would be amazing. I'm stuck in a really bad place right now. 
Thanks
