Can't Boot from External Partition

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.
