Ok, I'm in a conundrum. I tried to factory reset my iMac early 2009 24in computer.
I did the shift command r follow the steps to reinstall the OS x the last operating system I had was El Capitan. (I even tried shift option command r)
it won't install the operating system now and the hard drive is locked and unrecognizable.
I tried to go using the time machine backup but there's none found.
I can't mount any of the drives / partitions either.
How do I get OS reinstalled?
