The most typical instances of this issue involve external FireWire drives that are used as backup or auxiliary boot volumes.
#HOW MAKE A PARTITION BOOT AGAIN WITH DISK GENIUS 3.7 MAC OS X#
In other words, for some users, when Mac OS X 10.3.7 is installed to a volume other than the current boot volume, the secondary drive will be non-bootable.

Mac OS X 10.3.7 may not properly boot when it is installed on a drive that is secondary at the time of installation. Mac OS X 10.3.7: Secondary volume booting problems Here is one report:Tuesday, Janu 03:00 AM PST If anyone remembers what this might be, please let me know. I've done this for years, on many OS release, and haven't seen a problem. Perhaps you can help me by explaining where the safety clone actually resides syncing the boot user files with the backup. The options in the dialog box becomes more than confusing with the explanations. Since the backup all files thing doesn't actually clone the user files by places them in third location ? to keep them simultaneously updated on both drives? I'm wondering if I actually am making a clone at all. I think I misunderstood the literature when I got SuperDuper. The problem is I now have no backup of my Tiger system on my boot drive, which I want to clone to a secure backup before I attempt the partitioning. I now have more active and needed files on the 800 than are on my internal drive, and I have backed this drive up to the 400. So, to make a long story long :-), I was trying to drag files back and forth/backup to reformat the old external 400 without losing files in the process. I am migrating from an old FW 400 to a FW800 as my main backup external, and both disks are 160 gig, which are bigger than the internal 60 gig boot drive. I wanted a secure backup which is bootable and an exact clone of the system and user files. I have used Carbon Copy cloner in the past, but i was getting disk corruptions, so I bought SuperDuper as a currently updated program.

If I partition the 1st backup, I'm going to be given some choices.

I am going to backup the external to a third drive used only for backup. Backing up something onto the external and then partitioning it won't really protect you, since the external is what would need to be protected. Understood, but I'm suggesting partitioning the external drive, not the internal.
