Help plz! Having made two backups (one Time Machine and one bootable SuperDuper), I would like to secure-erase my late 2009 iMac's HD and start afresh with a clean install of Mavericks. I did exactly this recently on my 2010 MPB having also made a bootable copy of Mavericks on a USB stick, and it worked perfectly. Not so with the iMac!
Until last night I was running Snow Leopard. The option to erase the machine's HD was greyed out in Disk Utility. I tried to boot in recovery mode repeatedly (cmd-r) but it would not let me, and just restarts as normal. Is my recovery partition missing? So next I booted in holding down the alt key and was able to install Mavericks over the existing. I still have no options to erase HD and still cannot boot in recovery. Over to you!
