Cannot see SD partition as startup disk
 

Hi,

I have been backing up my MB Pro HDD using SuperDuper for a while now and have successfully booted from that partition. I upgraded to Leopard a few days ago and am experiencing too many issues so thought I would restore to my SuperDuper partition with the previous version of OS X, however I cannot see that disk as a Startup Disk in the System Prefs.

It was there (even after installing Leopard) and I can see the disk itself from the OS and open and explore it - just seems that it's not recognised as bootable. I had to force reboot (power off) my laptop quite a few times this morning - not sure if that had something to do with it.

I have run a verify on all disks. The odd thing is, in Disk Util, it seems bootable drives allow you to 'Verify Disk Permissions' while non-bootable ones only allow 'Verify Disk' - my SuperDuper partition allows 'Verify Disk Permissions' which would suggest it is bootable.

Can anyone advise how I can boot from this partiion please?

Many thanks

Darius

I'd try Option+Power On and selecting the drive in that chooser, Darius.

Just tried that and it worked, thanks. Am now in the process of restoring Tiger onto my internal HDD. It was far too soon to upgrade...

Thank heavens for SuperDuper.

Glad we could be there for you.
