Q: Partition Error - target disk too small

On my 3.1Ghz iMac running OSX 10.8.5 I'm trying to Partition my Hard drive so I can setup a second boot.

Currently my Macintosh HD has 404.07GB USED and 707.75 AVAILABLE.

I'm trying to add a partition that is about 350GB. But when I do so, it gives an error that the Target Disk Is Too Small.

Why is this? How can I get around this?

I have included screenshots from my Disk Utility:

iMac, OS X Mountain Lion (10.8.5)

You can't resize a Core Storage logical volume. You would have to start up in Recovery mode and destroy the logical volume group (also destroying all data in the process), partition, and then restore the data from a backup. Almost certainly this is not a good idea unless you need to dual boot, but that wasn't your question.

Thanks for. The info. I wanted to install both Final Cut Pro 7 and X. But from what I understand they don't recommend installing them on the same partition.

I wonder if I could use an external drive to create a boot drive for version X?
