I'm having some trouble with my system in my MacBook Pro. and after looking things over, the fellow at the Genius Bar recommended doing an archive and install first, and if that didn't work, then do an erase and install. When I do a reinstall from the recovery partition however, I'm not given those options, it just reinstalls the system. I did that, but the problem persists, so I guess I need to do an erase and install. Should I be able to do that from the recovery partition? Im not getting an option for that.
