clean install without USB drive... possible?

[Frozzie]

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

yeah.

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).

I just used the video at How-to Create MAC OSX 10.9 Mavericks Bootable USB Disk and download a free copy.

Here is the video:

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.
