Hi Alan, Yes, I wanted your to Reset the PRAM and then follow my original instructions of reinstalling Mavericks. I thought my intentions were always clear from the start, and my instructions were clear - My intentions were to get your 2009 iMac working correctly again ;-))
Don't connect the external drives until you are absolutely sure everything is working as it should. If it is, do a bootable backup, so you then have a current backup to fall back on if the external drives cause problems again.
