I am trying to install OS onto the Hard Drive after a full restore. The Hard Drive says it is full!
When I erase or partition the drive it fails every time. First aid conpletes but I am struggling to get it back to fresh.
When trying to select the drive for OS to install on its not showing. (Maybe because its full?)
Thanks for any help you can provide.
Questa è una buona domanda?

If you have a good TimeMachine backup you should be able to delete the current partitions and then reformat the drive with a fresh partition. But you'll need to create a boot disk to do this right. So you'll need a 16 GB USB thumb drive then from a working Mac follow this guide: How to create a bootable macOS Sierra installer drive
Then boot up using your install drive. When you here the Bong, Press the Option key to get to the Boot manager so you can select the USB drive. But before you run the installer, run Disk Utility to test the drive (Disk First Aid) again and then delete the partitions. The OS installer will setup the partitions for you and install the newer system firmware so you can gain Internet recovery services.
Once the OS is installed (it may take a bit of time so I would start it up and let it be for the night) see if the partitions are correctly sized. Then do your TimeMachine restore. If not your drive may need to be replaced.
Be careful here, as your system uses a special drive which has an internal thermal sensor configured per Apples specs so you'll need to use this: OWC In-line Digital Thermal Sensor for iMac 2011 Hard Drive Upgrade which replaces the internal with an external sensor so you can use any HD or even a SSD! Here's the IFIXIT guide you'll need to follow: iMac Intel 27" EMC 2429 Hard Drive Replacement

For some reason ot wont let me open up boot manager by option key.
I've made a video to help show you the problem...
@alxmac - I think I see the problem! You are trying to run the installer from a disk image which was mounted from the HD directly.
Your facing the cobblers conundrum! He can't fix your shoes when your in them.
You'll need to find a friend with a Mac system to help you create a bootable installation drive. I would recommend getting a 16GB USB and flow this guide: How to create a bootable macOS Sierra installer drive. That should fix your access problem.

What does the 'About This Mac' say? It should clear up the confusion as thats from the logic board its self.
Did you get your system serviced before?
