I'm running my PowerBook as it came from the factory. I'd like to create a new partition to install Tiger to play with it. Since switching two years ago, I've never had a reason to create a new partition so therefore I'm a little unfamiliar with it exactly how it's done. I know that in order to create a new partition I must boot from my Panther install disk and go into disk utility and create the new partition. However, will this wipe out my current OS & data on this partition or simply reduce the size of it? Installing Tiger is not that important if I have to do a complete backup and reinstall of Panther.
