I am new to this forum and just lost my post. So here a short version: I need to remove Boot Camp and restore the disk space to OSX. There are some issues: it is a Mac AIR with no optical, CD or other external drives, it is a gift so the user is EXTREME intimidated by the machine, I am helping remotely and the best is that there is NO space on the OSX partition even after removing the data and leaving only the programs. I have followed the help provided by simsaladimbamba yet at step 4 we get a different screen with has two options and only the 'Download latest Windows support software from Apple" not 'Install or remove Windows 7' (grayed out). I believe the computer is using Tiger or Leopard (not Snow Leopard) as we want to upgrade and can't due to disk size. Need the space badly. Thanks in advance.
