I have a IMac A1225 model and just recently replaced the hard drive due to ongoing issues. The drive is brand new and blank with no data I need to reinstall OS X how do i do that? I have no discs etc as i purchased the iMac second hand 4 years ago. Can some one please explain the steps required to get this running again.
Follow the instructions at > How to reinstall macOS - Apple Support
Make sure to study the instructions carefully first, because you need to "Format" the new drive "GUID Partition Map / Mac OS Extended (Journaled)" with Disk Utility, before you can install macOS onto it.
Here is the list of models that could be upgraded to use recovery:

So, yours doesn't appear to be one of those which means you will need an install disk. Call Apple with your serial number and ask for replacement disks. Apple sells OS 10.6.3 in the Apple store for $20 - that may be another way, but it will only work if yours originally came with something earlier than 10.6.3 which Apple should be able to tell you.

It depends on the exact model/year of the Mac - any Mac manufactured up to mid 2010 came with install media and some - depending on age - will not work with internet recovery. It makes no difference when you bought it. If that is the case, you would need an install disk. Can you check your serial number with Apple (it's on the bottom of the stand) to find out exactly what model/year this machine is.
That means it cannot find what it needs to boot up. As I said, your Mac is too old to work with recovery. You need an install disk - there is no other way.
If you had cloned your system to the new drive before installing it, it would have been easy. But, you installed an empty drive, so you need to start from scratch.
Thank you for the reply but is this going to work as the disk installed is brand new with no previous OS on it basically blank disc.
Ok i have started the process and i went with the Command-R but all i get is a grey screen with a round circle and a line through it then the system shuts down.
Try Internet Recovery by holding down Command + Option +R. You should get a spinning globe and it will take a while.
Ok the EMC is 2267 and Model is A1225 by memory its a 2009
Ok when i do this option it comes up with a flashing folder with a ? in it
Thats okay i managed to purchase the discs and should have them later this week. I will post up once i get them
