    Is there a way to download OS X Mavericks from the app store and put dmg file into like a isolated partition and boot from it instead of using a USB drive? Interested to know thanks

    you could just make a partition and put it on that instead.

    but a usb would be better because

    1. you won't lose space on your drive.

    2. you could reformat the whole drive from a usb (which you won't be able to do from a bootable partition).

    You could also use another computer's drive via target disk mode (firewire or thunderbolt). Once you've made the bootable installation, change startup disk in system preferences.
