My iMac (21.5-inch, Late 2009) running OS X 10.11.5 will not start up in Recovery Mode, Safe Mode or any other mode using keyboard commands on restart. Nor can I reset the PRAM etc. The Recovery HD is there (disk0s3 650mb) but it does not show in System Preference>StartUp Disk. I figured I'd reinstall OS X so made an El Capitan boot flash drive but even though it mounts on the desktop it doesn't boot from it when I hold down the option key at restart and it also doesn't show in in System Preferences as a boot option. I can't even boot to Internet Recovery. For all startup commands the Mac boots as normal to the login screen. Please help!
