    Reinstall Mavericks
    I have an iMac with Win 7 and OS X bootcamped. I am trying to install Mavericks after my OS X partition was corrupted. I have downloaded the Mavericks Installer on my MacBook and have transferred it to a flash drive. When I boot and hold down the option button, I assume it will detect the flash drive and give me an option to install Mavericks. I want to make sure that my Windows partition is not damaged in the Mavericks install process. Will it give me an option of which partition to install onto? Do I need to format the corrupt partition first? Some pointers would be appreciated.

    How did you "transfer" it to a flash drive? You need to create a bootable installer like this Creating a bootable OS X installer in OS X Mavericks.

    I downloaded Mavericks OS from the app store, formatted a flash drive, called it "Untitled" and ran the following command from a terminal prompt:

    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

    Ok, when you start up your mac hold Option. This will give you the choices you are able to start up from. You can insert the USB drive now and your mac will see it. Select the USB drive and start up from that. From there go into Disk Utility and format the partition you want to install Mavericks on.

    Thanks. I am reinstalling because I had trouble updating to Mavericks and the "solution" I found was to delete and merge the recovery partition which is now sitting there blank.

    Should I merge the small (620MB) recovery partition with the main OS X partition or should I just leave it there?

    Thanks. All good. Was able to successfully install from there.
