When I power on my iMac, it shows me the Apple logo for a minute and then a white screen with a circle with a line through it. I read on this site that this is due to a bad hard drive, so I replaced my hard drive with the recommended 2T Seagate (I am pretty handy). After hard drive replacement, I still have the same issue. I have tried holding down COMMAND R, and OPTION during power-up, but it doesn’t change anything. That is supposed to take me to the disk utility menu so I can restore from my Time Machine drive, but it doesn’t happen. Only the white circle with a line through it. What else could be wrong?
If you can’t start up from macOS Recovery Newer Mac computers and some older Mac computers automatically try to start up from macOS Recovery over the Internet when unable to start up from the built-in recovery system. When that happens, you see a spinning globe instead of an Apple logo during startup. To manually start up from macOS Recovery over the Internet, hold down Option-Command-R at startup. If you still can’t start up from macOS Recovery, and you have a Mac that is able to start up completely, you might be able to create an external Mac startup disk to start up from instead. https://support.apple.com/en-us/HT202796
Try creating a bootable USB and use that to get into the install, then you can get into disk utility and restore it.
Hi Curt, just to clarify since it is possibly a 2009 make it will not have internet recovery, so performing an time machine would be ideal if you have it. You can try all processes below, except it may be wise to reopen device and check all connections as if you were prompted with same error message could be the cable it self and not the drive as i replace many Mac and high possibility it is the hard drive or reseating the cable. Performing the cmd+r - will boot you into the utility menu and select time machine when it appears Though you can also press and hold the option key when your external drive is connected and be patient as it takes a bit longer than newer units. while holding the Option key only you will see three drives if any appear New hard drive, recovery drive (if any) and your external boot drive. I have a few 2009 iMacs here and works but takes a good 30-50 seconds sometimes longer depending how much ram you may have for performance. Finally if you have another mac or a friend with a mac you can download El Capitan 10.11.x OS X and create a bootable usb drive to boot from, but to be safe see if you have in purchases of the Mac App store or your friend to download the Mavericks version as some of the OS X’s require certain ram prior to installing on the Mac. Now this all depends on which model / year Mac that you have but a bootable Mavericks would do the trick going back to 2008 early iMac. Thanks www.MacOSGenius.com

Problem Solved. First, turned your troubled Mac into an external hard drive by pressing the “T” key while starting up. Connect your troubled Mac to a good working Mac with the same OS or higher (connecting cables will vary depending on the year and model of your troubled Mac). Open Disk Utility on your good working Mac then select the troubled hard drive. Click the repair button; DONE! That will solve your problem. No reinstalling no OS or reformatting anything nor using TimeMachine… BTW, once your problem is solved backup or clone your now working Mac. I prefer cloning. I hope this helps you, peace!
