Clone Drive Doesn’t Boot

Currently running Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina on an Ivy Bridge desktop for over a year with no issues. I’m on OpenCore 0.9.4.

I want to upgrade to a larger HDD. Currently running on a WD SSD 250G, and moving to a Crucial 500G SSD. I have tried cloning with Super Duper and CCC. I copied my EFI contents to the new drive’s EFI.

When I boot and disconnect the old drive I only get a black screen and I even use boot options to ensure I select the drive. I have tried waiting, pressing space bar, etc to see if maybe it’s just graphics not loading, but there’s also no HDD activity so I doubt any processes are running in the background.

When I boot with the old drive connected it shows up in the boot picker and I can get into it.

I’ve read through the Dortania guide again to make sure I’m not missing anything and nothing sticks out.

Looking for advice. Thanks
