    For a number of reasons I need to reformat my computer. I have a 2011 Mac Mini so I can't pop in a CD. I'm in the restoration menu, and when I try to reinstall OS X, it says the 500GB HD is locked.

    Do I have to erase it before?

    YES. IF you got to the restore menu it should allow you to go to disk utility. reformat the disk then install windows
