    I just installed an SSD (and kept my hard drive). If I hold down the Option key at bootup, the hard drive and the SSD show up as boot options and I can boot to the SSD. However if I go into System Preferences->Startup Disk, only my hard disk shows up. Finder and disk utility also show the SSD.
    How can I boot to the SSD without going through the Option key each time?
    Mavericks on a mid-2011 21.5" iMac.

    Try this...

    Boot into recovery partition "holding CMD + R during boot"

    Open disk utility

    Choose SSD

    Repair disk (check if there is any error)

    Repair permission

    Quit disk utility

    Choose the SSD as start up disk

    Tried everything noted below. SSD still does not show up as an option for Boot Disk.

    Maybe zapping the PRAM or an SMC reset would have an effect?

    Otherwise maybe wipe SSD drive and re-install or re-clone the OS as the case may be?

    Tried both - no joy. I'd like to save wipe/re-install as a last resort since I've got quite a few installed apps including Parallels & Windows.

    It doesn't show up when you go to Start Disk after having booted from either of the drives?

    Did you "prep and test" the new drive BEFORE you installed it into the iMac, using an external enclosure or USB3/SATA dock?
