Windows keys on a Mac keyboard
A Mac keyboard has many keys that function the same as keys on a Windows keyboard but have different names.

Thank you - I did exactly what @Fishrrman suggested above. Pressed the equiv keys for Mac windows + alt + R and boot into the exact same recovery mode screen as in the photo above.Windows keys on a Mac keyboard

I doubt your machine has an internet recovery as I know for sure that cMP5,1, which is a 2010 machine does not have it.I boot into the exact same screen in the previously attached photo
Thanks. Is it possible to use Mist on a Silicon M1 to create a Mavericks boot disk for the iMac 20" / A1224?I doubt your machine has an internet recovery as I know for sure that cMP5,1, which is a 2010 machine does not have it.
To force internet recovery use ⌘ ⌥ R (check the corresponding PC keyboard keys). And if you did not download in the past Mavericks from the App Store you won't be able to reinstall Mavericks there. You can install later macOS by creating a bootable USB and if you specifically need Mavericks there like I said before, partition that drive for Mavericks restore.
This application can download all macOS's in the past (except Mavericks) and create a USB installer. Only Mavericks will ask you to login.

Just downloaded Mist. I don't see Mavericks on the list to download on the Installers tab. I will try downloading El Capitain as this iMac is compatible with this version and make a boot disc...this is the step I've been stuck with in the past

You can use Mist to download an El Capitan installation app, but Mist can't create USB installers or ISOs for anything older than Big Sur when run on Apple Silicon hardware. To create a bootable installer you would run the createinstallmedia program included in the El Capitan installation app. createinstallmedia almost certainly has an invalid signature (expired) so you may need to remove the signature with codesign. I had to do this on Sonoma in order to create a Mojave install USB.Just downloaded Mist. I don't see Mavericks on the list to download on the Installers tab.

createinstallmedia is an Intel executable and those can be run on M1 systems after Rosetta has been installed. The OS should offer to install Rosetta the first time you try to run an Intel executable. As I mentioned before, Mojave's version of createinstallmedia refused to run on Sonoma until I stripped the signature.Thank you - i thought I cannot run createinstallmedia on an M1 - ?

The previous post by @gilby101 jogged my memory to suggest an easier way to get you on Mavericks if that's what you want. Download the Mavericks ISO from archive.org (be patient, it could take a while). Then download Etcher and install it on your M1. Use Etcher to write the ISO contents to a USB stick. You may need to give Etcher full disk access privileges before it can write to the USB stick. Now boot from the USB stick on your old iMac to install Mavericks.
Thanks - I do not need any data on the iMac, just want to start fresh. I have already deleted the partition via disk utilOP wrote:

What options do I have?"
Hmmm... that screen is what you're SUPPOSED TO SEE when you boot to internet recovery.
In your original post, you said you wanted to do "a fresh install", right?
We need to clarify that:
Do you want a "completely fresh" start (this means "erase everything and start over", restoring from a backup if you have one) ??
Or does it mean you want only a fresh OS installed (leaving the rest of the data intact) ??
What I would suggest is an erase and install.
Here's how to do it:
1. Boot to internet recovery, as you did before.
2. From the utilities screen, open disk utility.
3. VERY IMPORTANT -- you must check to see if there's a "view" menu in disk utility (older versions don't have it). If there IS a view menu, go to it and choose "show all devices". If there isn't a view menu, don't worry about it and go to next step.
4. Next, look at "the list on the left". The TOPMOST item in the list should represent the physical drive inside the iMac.
5. Click on the line for the drive, and click erase.
6. Although I don't recall seeing what YEAR your Mac was made, I'm guessing it's an older one, so erase the drive to "Mac OS extended, journaling enabled, GUID partition format".
7. When the erase is done, quit disk utility and open the OS installer.
8. Again, without knowing exactly WHICH iMac you have, can only guess at which OS the installer will offer. My advice is to accept whatever version of the OS you are offered. Remember the old saying, "any port in a storm".
9. Begin "clicking through" the install. The Mac will restart several times, and the screen may go dark for a minute or more with no other indication of activity. Just be patient.
10. When done, you should see the initial setup screen (choose your language). IF YOU HAVE A BACKUP, connect it now. Then "click through".
11. Again, if you connected a backup, setup assistant will ask if you wish to migrate from another drive. So "point the way" to the backup and give SA time to digest things. I suggest you just "migrate it all" and let SA do its job.
12. If you DON'T have a backup, then it's time to create a new account, etc.
Good luck.
To install Mavericks as suggested in my previous post, you'll need to change the date before the install will complete. This is because the installer's certificate has long ago expired. To change the date, use the Utilities menu in the top bar to open a terminal. In the terminal, typedate 100821002014
which will change the date to October 8, 2014. After changing the date, you can exit the terminal, use disk utility to erase the target disk, then install the OS.
That machine has no internet recovery. This screen comes later when you select reinstall operating system. The login prompt to your iCloud account is only required for Mavericks if not using the full installer, just because it is not freely available, but you must have downloaded it from the Apple Store in the past.Hmmm... that screen is what you're SUPPOSED TO SEE when you boot to internet recovery.
