Can't Boot from External Partition

This isn't something I've hit before, Goldie, so sorry if there's a bit of hunting in the dark!

Actually the version of the OS I installed off the disk is 10.3.3
The version on my internal drive is 10.3.8
Didn't occur to me to update the external partition OS.
I figured it was just a test to see if I could actually boot from either of the external partitions.
Is it worth my while to update that external OS & try again?

I don't think I can try the Smart Updating as I only downloaded the basic trial version of SuperDuper. I wanted to check that it all worked for me before paying for the full install.

Understood. The version of the OS shouldn't matter, but I figured it was probably worth checking. But regardless, the partition should clearly show up in the Option list.

How did you create the partitions in the first place? Can we try recreating them under your current OS?

If you'll send the information to support, along with name/email, I'll send you out an evaluation key so you can try Smart Update, should you need to.

I only created the partitions last week.
I'm still on 10.3.8
Actually I am trying to get my back up procedure sorted before I update to 10.3.9

Previously I had no partition, just the 250GB external that I was cloning my internal to using CCC.
When I made the switch to SuperDuper I had a rethink & decided to partition the external.
So it's pretty recent & done under my current OS.

I will get that info & send to you.
Many thanks for your assistance.
