    I bought and installed SSD to Mac Pro but it failed so I took it out for replacement. BUT, I formatted previous HDD and even I tried OPT+power on, it doesn't show anything. What am I suppose to do? Do I have to wait till I get new SSD to install OS X?

    From the the limited information provided, it seems to me that you should be able to install the OS on the old formatted HDD the same way you were going to install it on the SSD.
