Now that Macs are not able to boot into "classic" (ie OS9), X and classic must be installed on the same partition. You can't even start-up norton Systemworks from the CD anymore b/c it is an OS9 system. Essentially, if you want to be able to unmount a system disk (as is done with SpeedDisk and DiskDoctor when problems are found and other utilities), you must install a system on TWO partitions, both with OS X and Classic, and boot from one and optimize the other, then boot to the other and optimize the first one. If you have three or four partitions or more, then all you need is two of them with a system. It really sucks, but we can just hope that Symantic and other companies that make bootable CDs are going to find a way to get a stripped down version of OS X on a CD along with their programs, and we also must hope that they are willing to put forth the resources to do this.
