Hi everyone, I have recently replaced a failed HDD in my mid-2011 iMac. Physical installation was easy, but cannot boot into macOS/OS X. I understand that my iMac shipped with OS X 10.6.6 Snow Leopard, so it can only be installed on to a new drive with that specific version. I hunted around for the original installer disk to no avail. Next I tried finding .dmg installers so I could boot off of a USB, again to no avail (I currently only have access to Windows machines so ISO disk images are useless). I have no current way to reinstall OS X 10.6.6 on my Mac. Is anyone able to help me obtain either an original SL installer disk for a mid-2011 iMac, or an OS X 10.6.6 .dmg file?

SOLVED!!!!

I completely disassembled my iMac, gave it a much required clean, removed the video card, and baked in the oven at 200 degrees celsius for 8 minutes. Applied some homemade thermal paste (will probably have to change later) and reassembled. I then plugged everything in and booted from the OS X 10.8 InstallESD.dmg, which to my delight brought up the recovery options, I am now happily installing Lion.

Issue: HDD failure and faulty graphics card.

Solution: Replacing HDD and Baking video card in oven at 200 degrees celsius for 8 minutes.

PS, I am aware that the oven baking of the video card is a temporary fix. When I next go into the Mac to apply some proper thermal paste, I plan to swap in an SSD too.

Thank you everyone for your continued support, and help throughout this process, especially to those who supplied me the .dmg files.
