Reverting a CoreStorage Volume I broke an installation of Deep Freeze on a Macbook by upgrading it to El Capitan. I'd like to get Deep Freeze to work again, but "This version of Deep Freeze cannot be installed on a Mac that has CoreStorage volume". There are many guides to reverting a CoreStorage volume on the internet, but the steps aren't working for me.

I open terminal and type "diskutil cs list" and get the list of volumes on the Macbook, the revertible area tells me "Yes (no decryption required)". When I type "diskutil cs revert [logical volume UUID]" I get the error "The given UUID is not a valid CoreStorage Logical Volume UUID. I erased the hard drive and installed El Capitan fresh making sure to uncheck FileVault when I was setting it up, but I'm still getting the same error. Is there another method for disabling CoreStorage on Macbooks that I'm not aware of? Appreciate any help regarding this.
I ended up stumbling across the answer to my own questions (although David is right, I could have avoided it by following his steps). The guides I found all pointed to the first UUID, but it's actually the 4th one after running the disktutil cs list command. Simple, but took me forever to find. Thanks everyone!
