Hi, I had ubuntu installed on my mac and I erased it and now the hard drive looks like the attached thumbnail. When I try to install windows via Bootcamp, it doesnt let me make a bootcamp partition because it says that the hard drive should be 1 partition, but in mine there is some free space. I've tried draggins it to occupy the whole rectangle and clicking apply but it wont let me. I've also tried repairing disk permissions and it doesnt solve any problems. What can I do? Thanks.
