I am new to macbook os .so I got little confusion on restoring/reformatting macbook to os x mavericks . My question is does restoring deletes all the partitions i had created? I have created 4 partition in my macbook 3 partition with 100gb and 1 partition(macintosh hd) i.e. where os x is installed with 200 gb so my question is can i only restore macintosh hd for clean installing os x??? without loosing datas on other drives Thanks in advance.
