I have a summer 2001 iMac G3 which currently has Mac OS X 10.1 installed. I want to install Mac OS X 10.3 on it, but I want access to 10.1 as well. I know to do this I have to partition the disk, but when I open up Disk Utility to do this I know that I won't be able to make any changes to the startup disk. Is there a way to boot up to Disk Utility so I can make the partition? Or will I be able to make the partition directly from the 10.3 disc? Thanks!
