Hi, my friend who fixes PC's and resells them bought an older iMac on eBay dirt cheap with no history. He brought to me, because I know my way around a Mac, certainly better than him, self admitted. His business partner put a Windows OS disc in the optical drive and it got stuck (lmfao). I got that out easily by booting and holding the left mouse key. Then, immediately I noticed no startup chime, so I did a PRAM reset lickedy split, fixed it. Now, trying to get to Internet recovery is not fun for me at all. Won't recognize my command, but recognized PRAM and ejected the disc and recognized the option key. I'm using a USB Dell keyboard and USB mouse. All I'm getting is the gray file with the ghosted ?...... Bad drive, bad ram, just keep trying??? I'm pressing and holding the Windows key and R, in place of command and the R..... Tried Alt and R, Control and R...... HDD SUPPOSEDLY WIPED!
