The install of El Capitan, at least what I thought was the installation, took a while. A screen shows up with the 10.11 logo stating to install click continue, agree to terms and install OS, I got the option to use disk utility, time machine or recovery or click the install button. I clicked, installation (from bootable flash drive) it stated to restart, with this done a message came that there was installation media on the destination volume, try again.
I restarted and got a progress bar (Apple logo above) which never fully finished, or it did but nothing happened. After walking away for an hour or two, I powered the machine down, restarted it with the option button to get the start up disk manager but only got the apple logo and progress bar, again. I tried to start in recovery mode, also in safe mode with the progress bar appearing after each attempt.
Obviously, I cannot access the drive to remove whatever install media is present on that disk. What options do I have at this point?
Thank you
I
