In System Preferences select the external as Startup Disk and restart.
Download Mavericks and FCPX to that drive and run it.
Anytime startup into your original Boot-drive.

Apr 23, 2014 7:19 AM in response to nolanscottby Nick Treharne,Hi
I spent around 6 hours clearing out some crap from my original boot drive, bought Super Duper, cloned the drive to an external drive, booted from external drive, downloaded Mavericks, tried to install and got this... [see screen] (!!)
I tried to do as it says but can't changed the partition as it's the boot drive. What now?? Thanks

Apr 23, 2014 7:32 AM in response to Nick Treharneby Tom Wolsky,Do you have the 10.6.8 installer? Run it and install on the external drive. Boot to the external and update in the App Store to Mavericks. Install FCPX.

Apr 23, 2014 7:41 AM in response to Tom Wolskyby Nick Treharne,Thanks for the reply. I'm booted on the external drive with 10.6.8 OS, and trying to update in the app store, but Mavericks will not install on the external boot. Says "Doesn't use GUD partition". I followed the on-screen instructions, but Disk Utillity cannot change to GUD partition as it's the Boot Drive.
Apolgoes if I misread your answer. Suffering from acute Noobism.
Thanks

Apr 23, 2014 7:43 AM in response to Nick Treharneby Tom Wolsky,How did you get 10.6.8 on there if it isn't a GUID partition? You'll have to boot off the internal and erase and rebuilt the external as a GUID partition then reinstall 10.6.8.

Apr 23, 2014 7:55 AM in response to Tom Wolskyby Nick Treharne,Super Duper cloned the original intertnal drive to the external drive. So I have to basically have to Erase the external and add GUD then clone again?

Apr 23, 2014 8:04 AM in response to Nick Treharneby Tom Wolsky,Do not clone unless the cloning app can set the drive as a boot partition. CCC can do this. I don't know about SuperDuper. Create the GUID partition and install from the installer if you can.

Apr 23, 2014 8:19 AM in response to Tom Wolskyby Luis Sequeira1,What this story makes apparent is that Mavericks is more picky than SL about the partition map.
SL can boot from a drive which is partitioned using APM, while Mavericks cannot.
You can still clone with SuperDuper, but you'll have to erase and change the partition to GUID first.
In Disk Utility, select the drive, click on "Partition", choose the desired number of partitions, and then click the Options button. It should look like this:
