error while installing MacOS Monterey

There are reports appearing on the ASC Forums regarding failed installation of Monterey on older Qualifying Apple Computers. In most cases this is related to having a NON Apple Original internal drive ?  

The EFI Boot ROM included in Monterey is verifying for Original Apple Drive and if not found , may Balk or fail to upgrade to Monterey. 

Reports indicate the EFI BOOT ROM is Required to Flash the Computer and is a  requirement for a Successful Monterey Installation.

What is the exact wording of the error message?

Where in the update process are you getting that message?

Possible problems:

You need an Apple disk installed to upgrade to Monterey since the upgrade includes an update to the Mac's firmware. That update looks for an Apple disk and write to the dick to do the firmware update. The install will terminate or freeze if no Apple disk.

Do you have enough free disk space?

• If upgrading from macOS Sierra or later, your Mac needs 26GB of available storage to upgrade. If upgrading from an earlier release, your Mac needs up to 44GB of available storage.

Do you have any antivirus or clean apps installed? Id so uninstall them udding the app's instructions.

To see what disk is installed,click on Apple icon in upper left and select About This Mac>System Report>Hardware>Storage>the internal disk>and the manufacturer would be under Physical Drive>Device Name. An Apple drive says Apple.

If possible to get an Original Apple Drive and flip out the After Market drive and pop in the Original drive - format etc and run the Monterey Installer to that drive. Then, reverse the previous step and run the Monterey Installer again to the after Market Drive.

Presto - Monterey should install.

Same problem here. I just checked my Storage and it's Apple Hardware but, even so, I can't install the new OS.
