I was using El Capitan without issues till now. I'm starting to use Pro Tools 10 which is incompatible with El Capitan, so I will need to install a previous OS X version like Mavericks to make it work.
I really don't want to transfer all my files and downgrade my Mac, so I came up with the idea of dual booting my Mac. Is there any way to install Mavericks and use it like it was another Mac, even though it would be in the same physical drive?
I won't need to share any files between these two OS, so I will be using Mavericks when I have work to do on Pro Tools, and El Capitan for the rest of the time.
I think I can get Mavericks from Internet Recovery, as my Mac came with this OS X version. Using a new version of Pro Tools (now compatible with El Capitan) isn't an option for me now.
Thanks!
PS: Just found this community and from what I read it seems great!

What you need to do is to create another partition on your Mac, and install Mavericks on it:
If you have the Mavericks version of Internet Recovery, as you said you might, you can boot into it by holding Command-N at startup and clicking "Reinstall OS X Mavericks", and skip to step 10 and onwards. However, it is possible that with an OS X upgrade the process upgraded your version of Internet Recovery to the El Capitan version, for example.
