Installed Yosemite on main partition.. pls help :(

-

i stupid download , install public beta of yosemite on main drive, overwriting mavericks.. thought easy go mavericks after testing little.

can please tell me how can install mavericks again? :)

don't have timemachine backups, stuff on external drives.

have tried cmd+r when booting installer, can install yosemite again.
 

unless yosemite has changed this, when enter recovery mode should able choose internet recovery, downloads software mac came with. last time did it downloaded mountain lion, , there upgraded mavericks again through app store.

also: if choose install startup disk install recent version (i.e. yosemite) while internet recovery downloads entire original os apple's server.
