Archive and Install Mavericks?

[Cave Man]

EDIT:Ugh - I forgot about the recovery boot. I am losing my mind....

I think I'm losing my mind. I need to do a fresh install of 10.9.5 on my Mac Pro, but after booting from a USB installer of Mavericks, I see no Option button on the "Install OS X" window. The drive I need to install to is there and it's selected, but in previous versions of OS X my recollection is once you clicked on the drive an Option button appeared that provided the Archive and Install. Am I misremembering this, or has something changed with Mavericks? I don't want to do a clean install because I have 1.5 TB of data to transfer and that will take 12 hours or so with Migration Assistant.

That option is gone, a default Mavericks install is in effect archive and install now and will replace (update) the OS but will not erase your personal data.

Reinstall OS X keeping your files and user settings intact

OS X Mavericks: Reinstall OS X

Use the built-in recovery disk to reinstall OS X while keeping your files and user settings intact.

Important: You must be connected to the Internet to reinstall OS X.
Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
If you’re not connected to the Internet, choose a network from the Wi-Fi menu (in the top-right corner of the screen).
Select Reinstall OS X, then click Continue.
Follow the onscreen instructions. In the pane where you select a disk, select your current OS X disk (in most cases, it’s the only one available).
