Install mavericks / yosemite without media

[K-Line]

hi

my scenario is: a macbook pro with a fresh new hard drive
with the previous hard drive it was installed mavericks
I don't have that drive anymore and i don't have any cd or dvd to install os x from those.

I'm wondering which way is the best to install mavericks or Yosemite on my macbook pro, and if i need or not the media with the os or I can do a network installation

thanks

How old is your Mac? Most new(ish) macs can boot right into the recovery mode even on a fresh drive.

Short of that, you'll have to buy Snow Leopard somewhere since that's the last version of OS X distributed on disc. I think Lion had a USB installer, so that might be an option if you can find it.

Hi,

you should be able to use Internet Recovery.

Your model supports it : http://support.apple.com/kb/HT4904

Restart the computer and hold Cmd + r on chime.
This would launch the Recovery System if you had a Recovery partition.

If your drive is blank, this will launch Internet Recovery : after a first download, the "Utilities" window will show up.
Select Disk Utility to format (Mac OS extended journaled) your drive.

Then quit Disk Utility and wait for the ~5 GB download and install.

Connect your Mac via Ethernet if possible, and disable the wifi.
