I am about to re-install OS Lion on my MacBook Pro. But before that I want to make sure that my data in other partition created, will that be lost to?
Example I have 3 partitions
1)Macintosh HD (OS installed in this drive)
So if I re-install the OS Lion using recovery mode from HD, will it also wipe out my other two partitions or only will clear "Macintosh HD" partition and install a fresh Lion copy?
